[@charlesgreathouse7376]

@Harry. B. Renner. jr. I don't care about computer efficiency. Electronic sensors fail. I want old school simplicity.

[@erikturner5073]

@Harry. B. Renner. jr. no todays cars are not easier. Scanners point you in the right direction, thats it. Without that scanner to see which system has the problem or if it's the communication network, your screwed. Also you still have to track down the electrical circuit and check to make sure there are not any other systems tied to that circuit(flow chart needed). You still may need to do your leg work with drivability and electrical. Today's cars are very intricate and can be very difficult even for a master technician, and THAT'S THE TRUTH. I'm speaking from experience. I could do EFI on my builds, but I love carbureted old school. There is nothing wrong with old tech if you know what your doing and you get great results with far less money. Plus with a basic setup it's actually much easier!!! No computers, sub systems excessive wiring and communication networks, etc. With old school cars you can figure out without a scanner with and understanding of what your dealing with.

[@erikturner5073]

@Harry. B. Renner. jr. try diagnosing today's cars without interfacing with a scanner!! It not happening buddy! I've been doing this for 26 years and today if a system develops issues you won't effectively know which direction to go without taking that first step after checking the basics. With old school all you need is a fundamental understanding of the system and a manual (repair book) and your all set. No high dollar scanners needed!! Sorry to burst your technology loving bubble but these are the FACTS!!!!👍 Especially in a grid down situation, no internet means no All data, or Mitchell on Demand!🤣😂 An old school carbureted sys with electronic ignition, or points you can get up and running with the proper BOOK style manual and the knowledge of the system. No scanners needed. Old school is easier and can be efficient with the proper know-how. Of course not many people have old school knowledge and most of them at the same time criticise not knowing what they are talking about.

[@killer2600]

@@erikturner5073 You can get service manuals and repair books for today's vehicles. Also you don't need a high dollar scanner, many get by with low-end scanners. As far as which is easier, old vs new, new is hands down easier. Computer diagnostics speeds up the diagnostic part of repair. Got a misfire, the computer will tell you what cylinder to look at. Before computers, you checked all the cylinders one by one.

[@SweatyFatGuy]

You started showing up in my feed recently. I'm an old guy too, build carbs, engines, transmissions, entire cars, plus I do EFI and other modern tech, often putting it in my 40+ year old cars. daily driver is a 65 GTO with a 455 that runs solely on E85 and E100 in it. I make E100 from tree sap and cattails, 10 cents a gallon lets me run my huge V8s with 13:1 around on the street all summer. Here is more info on the modern gas. The reason why it is boiling over far easier than it used to has to do with the multiple components that make up gasoline, the stuff that comes from oil. Ethanol has a 173F boiling point at sea level, it goes up with pressure like most other boiling points, but that is not what is causing the problem. Ethanol is somewhat counter intuitive if you know gasoline, its very different but raises octane considerably. That 10% ethanol they mix in raises the octane from 60/70 in the base gasoline to 87/93, depending on the mix of the gasoline components. The boiling points for what constitutes ethanol free gasoline has boiling points that range from 80F to 450F, flash points are equally varied and all over the place. Octane for each component tends to go up with boiling and flash points. So what they can do now is mix in the very light parts of gasoline that have a naturally low octane, and get it to run without knocking by adding 10% vodka to it. So that stuff boils in the lines or tank on a hot enough day. Where I live its rarely above 80F, so we get the really crappy stuff up here, and they charge us a fortune for it. That is the reason I got into making vodka to run my cars, because 87 octane gas was $5 a gallon until 2015, and now its nearly $3 a gallon for 87, and I am not even close to California. The gas you buy in Georgia or Texas is different than the gas we get in the far northern reaches of Michigan. We get the light crap, you get the slightly heavier stuff, but its all lighter than it used to be. They can sell you the worse crap because ethanol improves is so much. They used to use tetraethyl lead to raise octane, and that just might be why the boomers and their parents have such a huge problem with Alzheimers. Though nobody will look into it because the class action would kill the oil companies. That caused cancer and all kinds of other problems, so it was discontinued when I was a little kid. Then they tried MTBE, and that too was very carcinogenic and harmful. Meanwhile ethanol is consumed by millions world wide daily, used in de-icers and to remove water from fuel systems, so its harmless as long as you aren't addicted to it or drink too much and pray to the porcelain god the next morning. It cleans the hell out of your fuel system, removes all the varnish gasoline leaves behind, also it allows you to burn any water that condenses in the fuel tank rather than sitting on the bottom, causing corrosion and then making the engine not want to run when it gets sucked into the pick up. Ethanol when burned only makes Co2 and H2O, runs cooler, and can handle more compression or boost than gasoline can, all the while making more power. Its fun stuff in your car in high percentages, essentially a race fuel for the street. I have almost 1000 miles on the oil change in the 65 this year, and it is still clean. That engine has never been run on pump gas since I rebuilt it back in 2011. I have to run a 195 thermostat in it to get it warm enough even cruising around Nebraska in 105F weather. Nothing special in the engine and fuel system, its all basic parts store stuff and 1967 vintage 72cc 400 heads on a flat top 455 with an additional .04 stroke, and my Qjets run great on it, the FiTech EFI did very well too. No problems with vapor lock, even with mechanical pumps, here in Michigan or in Nebraska where my family lives. Yeah I road trip the thing too and have other cars I run on E85/E100. When they found they can sell the really low boiling/flash point stuff for profit, they took advantage of it. I do not blame them, but where I take issue is how they then blame ethanol for the problems the gasoline is actually causing. Business is business though, you do what you must to make a buck. I don't think its the companies themselves spreading that, but people who simply do not know much about it. Before 2007 I was building everything to run pump gas, race gas got too expensive in 2005 so I dropped compression in most of them. Then when gas got to where 87 was $5 I looked into making my own fuel just so I could drive my cars and not be stuck in a modern appliance. I got quite adept at tuning for pump gas, getting 20mpg from one of my 455s on a 1500 mile road trip, 2004R, 2.93 gears, 27" tall tires, Qjet, and enough wheaties to push that 4100lb GTO into the high 12s with the stock converter and those gears, on 87 octane with 8.8:1 compression. It was an engine I spent all of $1900 rebuilding with cast pistons and a mild cam. I love 455s. Cars that quick have a hard time getting a mechanical pump to feed them, so most of my 400 and 455 powered vehicles have electric pumps by the tank. That really helps with vapor lock, and I never had a problem with it. So yeah the ethanol is causing the problem in that it allows the oil companies to sell you a not nearly as good quality gasoline, but on its own, it is not a problem. The additives they put in the 10% stuff are also an issue, Jeff Smith from Hot Rod Magazine and Summit Racing wrote an article about that. www.onallcylinders.com/2018/05/25/ask-away-jeff-smith-e85-pump-gas-additives-not-ethanol-cause-corrosion/

[@donkEEpunch85]

That was a great read! Wish I could pick your brain for a few days. I always hated EFI but that was mostly because I didn't understand it. I've learned a bit more in recent years and am now looking to install a Holley Sniper kit on my 4x4 bus project (Ford 351w/C6 Trans/3.73:1 gearing/32" tires) mainly for the reliability, also for the tuneability and gas mileage. Overall, cool stuff you're doing up there!

[@SweatyFatGuy]

@@donkEEpunch85 There is always more. I plan to start making some videos about cars, ethanol, producing energy yourself, and many other things I have found interesting over the years. I am not a hippy or tree hugger, more of a gearhead hot rodder. I got into ethanol fuels because it is 1 cheap and easy to make, and 2 makes more power than gasoline 3 runs cooler. Im working on building my house right now, and that takes up most of my time. I do everything myself, rarely have anyone to do things for me, but will pay them to help me out. If I need to do or make something, I learn how to do it. Every job I have had has been a dirty hands on technical job, and many things apply though they seem to be disparate. Once the house is done, I will start making videos and putting them on here and maybe some other platforms, since youtube has a penchant for censorship of late.

[@LgSutterby]

An old farmer’s trick to avoid vaporlocking - clip a few wooden clothespins to the fuel line between the pump and carb (only works if it’s a metal line). The wooden clothespins act as heatsinks of sorts to draw the heat away from the fuel and keep it from vaporizing. I know it works because they’ve been on my ‘71 C10 for years and I’ve never had an issue after installing them!

[@MFE92]

I bought a '69 Lincoln Continental a few months ago. They are known for vapor lock, and people go to all kinds of great expensive lengths to cure it. Some go electric booster. Some go in-tank electric. Many insist on using an older style 3-port fuel pump that has a return line, but those pumps aren't available anymore, so it's a game of find and send out for refurb. It just so happens that the new pickup/sender I installed on it had a 3rd port, which I had capped off. Then I saw this video, and installed one of these filters pro-actively on the '69 Lincoln Continental before it got hot here in Phoenix. I ran the line back to that unused port on the pickup/sender. I am now driving this thing in 100-degree weather with zero vapor lock issues. Bravo, Uncle Tony!

[@OverlandOne]

Back in the 70's my 1970 440 magnum Plymouth Fury used to vapor lock on hot days when I parked it for a short time. All I did to cure it was to wrap my fuel line in aluminum foil. (From the pump all the way to the carb.) They ran those lines really close to very hot things and this insulated it by reflecting the heat from the line and it never happened again. It was not my idea, I think I read about it in Hotrod magazine or Popular Science or somewhere. I ran Ammoco 93 octane in it all the time and it had lead (ah, the old days) and no alcohol.

[@karljay7473]

You can also insulate the fuel line and run a heat shield under the carb. Some used to use a "turkey pan" that had the carb in what looks like a jumbo air filter box. Old Fords had a small cooler used for the power steering pump, looks like a tiny cooler, you can use that inline as well. Glad to see older cars being kept alive, they have real character.

[@av8tor261]

My 70 Cuda-440 had factory design anti vapour lock system as OEM. Great vid Tony. Thanks.

[@cobadogeats]

Blocking the exhaust crossover under the intake helps a ton too

[@frankconrad7323]

Yes. Plus back in the 60s we would put a lot of foil under the manifold. Which kept most of the heat away from the carb.

[@danielbrealey2924]

What about the old wooden carb spacer trick that boat racers used to do? The wood does a great job insulating the heat from the carb, and let's be honest in most cases the increase in manifold plenum it gives you increases hp too. Another little trick we use these days is with duel plane manifolds- the dividing wall at the point where the carb bolts on has a slight cut out in the middle with newer duel plane manifolds, it doesn't effect the way the manifold opperates at low to mid range RPM but allows it to breath a little better up top like a single plane does. It sort of becomes a hybrid manifold at this point. You only need to cut out 75% of the cross sectional area the dividing wall seperates (right in the middle of the dividing wall) and only needs to be around a 1/4" deep for best results. Just remember to stuff the inlet hole full of rags so the metal your machining away doesn't fall into the manifold- or you can remove it if your really concerned about not letting anything through the motor, which is tech the best way...

[@bennynash6655]

This video reminded me of our family camping trips. My parents had a 31 foot or so Airstream travel trailer which was pulled using a 1968 Ford Country Sedan Station Wagon. The 390 CI engine would vapor lock in the mountains while pulling the trailer. His fix was to clip on wooden clothes pins to the rubber fuel lines in the engine bay. It provided enough heat sink action to stop the vapor lock. Worked like a charm. I think they were still there when they sold the car, LOL. thanks for the memory. Good video.

You have addressed a problem, of which I had been explaining for years now (to no avail) because the excess heat vapor will be vented to the tank, will be adding more (minute amount, but still pressure vapor), and increasing fuel pressure to the fuel line, keeping a pressurized fuel line (minute, but still), & eliminating vapor lock. Nice to see people going in depth, & investigating these problems. Btw, I 'scribed!

All I can think of is Joe Namath talking about vapor lock on the Simpsons years ago.

[@bobbastion7335]

We used to get vapor lock here in the south decades ago before ethanol was a fuel additive and was imbibed instead. My understanding was that there were two formulas for gas back then. A summer blend and a winter blend. It was when summer arrived and we were still on winter gas that was the worst for vapor lock. That's when mama's clothes pins would go missing. Clothespins are effective and cheap but they ain't as pretty as that fancy vapor separator. Now I can take mama's clothespins off the '64. Thank's Tony.

[@secondthought2320]

Wished I had seen this video 15 yrs ago. My 396 had terrible vapor lock and I went through hundreds of wasted dollars before I ran across a guy that knew how to get rid of it. And here in Texas it always stayed hot during the summer , even just taking it easy going down the road. The 11.25 compression didn't help. Great video. Smart fix.

I've never had a carburetor vehicle quit running in the heat, but here in Canada where I live maybe it don't get hot enough. which I'm OK with, I hate the heat.

[@dlucas527]

Dude this is the besti information ever! I have a 1963 Lincoln Continentat Sedan. When I rebuilt the engine I was told it was not necessary to have the return fuel line. Having it not be reconnected gave me the vapor lock. If anyone knew what was going on they never said it to me. I could not figure it out. I am not a mechanic or have this as background but I have a very desirable car. I even had mechanics ask me if I wanted to sell the car. I feel so deceived. Thank your for this information. It means a lot.

[@Welcometofacsistube]

Tony: as a guy who’s in his 40’s with 10 Mopar’ in the backyard, you make me smile. Your old school knowledge is educating even a backyard mechanic like me. But if I may; part numbers for said filters?

[@immikeurnot]

I'm gonna throw this out there: When in doubt, use the type with an orifice. Liquids can only really flow as fast as the most restrictive part of the path. The flow rate across one .060 orifice is going to be close enough to identical to the flow rate across two of them.

Excellent tip. I have an auxiliary electric pump near the tank to overcome the vapor lock when it happens, but I'm still wasting fuel when it's flooding the engine. Your fix is definitely worth a shot. Thanks!

[@jesusbernal9025]

In old times i drove (and loved) a '78 f-150 with the vapor lock issue. It took me a few years of trial and error, 'till i installed a layer of fiberglass insulation directly atached to the hood underside. It reduced the problem by 70% plus.

That’s actually a really good fix I was taught that you needed to cool everything better if you experienced vapor lock but I have never owned a carbureted vehicle yet still want one for the cool factor 😎

Tony I have a 69 GTX that suffered from vapor lock so I did exactly what you did to your road runner and it worked . Thank you very much for the great advice. Ed

[@thechillhacker]

Dude I know I am necroposting, but thank you again Tony for more invaluable information. I rebuilt an 84 caprice wagon as my family cruiser, and I drive the hell out of my cars. Like a LOT of miles. Got this thing on the road, and all the hot rod shit (basement head job, hedders, intake, points retrofit, etc) ran fine. Great in fact. Thought I even designed her well for vapor lock well with lots of exposed copper/nickel alloy line in big cooling loops in front of the fans, with regulation, and a mech pump with return line, and a phenolic spacer on the carb and mostly blocked off crossovers, but as soon as I switched her over to the 10% ethynol crap, I started getting boiling issues after the whole car, not just the engine - warmed up to real operating temp, like after 30 min or so of real driving. Anyway, I will be switching my return style mech pump over for a normal returnless, and rerouting that return line to the wix 33040 i'm picking up in the morn, along with a check valve near the tank on the main feed line. Then I am driving hundreds of miles with half the family. This thing *WILL* obey me and run right even at full temp on cheap gas.

[@thechillhacker]

And, yes I know boiling is my issue as I can see it boiling in my final stage glass filter, along with jumpy regulator output pressure - the filter which I will be replacing with the regrettably opaque wix filter. Good thing I still have a pressure gauge on the regulator to monitor the output. hopefully should be less jumpy as a verification of success.

Learn so much on this channel. My first car was a 78 charger and this would happen all the time, but my 16 year old brain didn’t grasp the concept of vapor lock. Also helps this information is so easily accessible nowadays.

[@AthenaKolva]

Thank you Uncle Tony for helping me learn classic cars, I have no friends or family that know about these so I'm mostly learning the hard way, by making mistakes!

[@edspencer7121]

About a week ago I subbed your channel. The straight forward way you put your information out to the viewer is very refreshing. My dad has a 1966 Olds 442 that vapor locks,there's an extra steel line that runs back to the tank. Now I know why! What was the part numbers for those Wix filters by chance? Just a side note, I'm into the Ford Falcons and you would not believe all the gripes about vapor lock on the forum sights. This is one video for sure I'm going to share on these sights. I've always wanted a late 60s 2 door Dart. My cousin last night tells me he has a lead on a clean 67/68 with a slant 6 in it for a reasonable price. Looks like it's time to squeeze more room out of the corral.........

[@paulkirkland1535]

Uncle Tony; You're 100% correct. About 25 years ago I had a similar problem with a Chevy S10 pick up. I was having difficulty starting after a hot soak and after installing whats called a "spill pot", I was able to solve this issue. If memory serves me correctly I think it was a Mopar service part similar to what you describe. So again you are certainly correct and the pick up ran great ever since. Have a great day sir.
