Slaghammer Mystery Solved! When Unlikely Problems Happen In The Last Place You'd Look

Last time at the track, we found our previously sweet running 383 all of a sudden sounding ragged, slowing down and then mysteriously closing up the gap on one of it's spark plugs.
We were set to go again last night and hopefully solve the plug issue, when new gremlins struck us before we even.left our pit.
We came home and started troubleshooting only to find something completely unexpected in a length of braided line made of materials we had never even seen before.

I made the massive mistake of buying some black braided fuel line off of Amazon during 2020 shortages. That stuff ruptured and leaked everywhere within a few months. Very dangerous stuff, but I was lucky because it never came into contact with open flame. Gutted it and waited for quality line, and learned a lesson.

As an aviation guy, we have to do a bore check on fuel and hydraulic lines at scheduled times to detect this very issue. This applies to small aircraft here. We drop an appropriately sized ball bearing down the line to check for internal obstructions. Yes, the large commercial aircraft have those teflon lined hoses in the 3000PSI systems (brake lines etc) but those things are NOT cheap either.

I had a new (2 month old) intake hose for my Land Rover collapse and shutting down engine while going 55mph on the fwy! It wasn’t in contact with fuel but it did have contact with Chinese manufacturers.

[@raoulcruz4404]

Heard of this problem on LH Chrysler. Dude replaced the radiator and since he had it out, replaced the radiator hoses. Car would overheat driving down the road. Normal at idle. Turns out the lower radiator hose, Chinese, was a softer material. Read: cheap. It would collapse from the suction of the water pump. My new philosophy is: if it’s working, leave it alone. Installing Chinese parts is installing failure.

[@spankyham9607]

Looks to me like that braded hose was something that Autozone would sell in the "chrome gets you home" section of the store. One of those Spectre kits of braded this and braded that. Probably was vacuum line instead of fuel hose.

[@davidleonard8369]

That’s exactly what it is. I actually had people ask me to install that junk on their cars.

[@albertgaspar627]

two things: one, those kits never include a lower hose cover, which tells you something, and two, it's the same sheathing you can order from computer stores--they use it to bundle their wires on mainframes.

[@bobbyoshomebuilt2544]

I prefer hard line, especially now since they make the rust resistant stuff, which is also easy to form. I use minimal rubber (fuel injection rated) for connections only. I never liked the idea of not knowing what's going on inside the braided hose. At least with unshielded rubber you can monitor the deterioration. I also love the look of hardline when done right. As always, thank you for the content, I really enjoy it!

[@cuda70gt7]

That braided line is from a hardware store like home depot. It is used for plumbing water lines. You can pick it up very cheap , looks like braided steel line and is stronger than plastic line but it is NOT for use in an automotive fuel system.

[@brandonchamberlain9179]

I was using a compression fitting to attach braided steel to a factory steel line. This had a rubber grommet it used as a seal. The grommet would slowly creep down the steel line inside the fitting, then close off the line like a check valve. Doing over 60mph it would stay open.. slow down and the line would close and you'd be dead in the water. Of course it happened in road construction, I5, downtown Seattle. Managed to get restarted and drove like hell for 2.5hrs to get home! lol

I had a stuck caliper as I was driving. I was able to knock it a bit loose with the handle of a snow brush, a very Canadian solution. It turned out that the brake hose had collapsed and held pressure like an unwanted check valve! Lesson learned, I replace my hoses every few years. They're cheap.

"it's only cheap when you do it once" I mean, i get it, we are looking to hot rod affordably, and avoid the "gold plated solution". Its why I tend to modify an OEM part (except single quad intake manifolds, a used aluminum performance model can often be found for less, if you have a place to store it until ready). but i'm also older, so my days of "gotta be the fastest with the mostest" are behind me. i just want to get 'er done, enjoy 'er on the road, get 'er sold, get the next one.

[@rockymeyers4030]

My preference has always been hard lines, typically the brake lines all the parts stores sells. It can handle high pressure, some OEM fuel filters have the same threads as the brake line fittings . I can cut it clean and put a slight flare on it to act as a barb for rubber hose. NHRA allows either 6 or 12 inches of rubber hose, i forget. Rubber is easier to inspect and troubleshoot than braided. Some parts stores sell rubber fuel line that is rated for EFI pressures and is teflon lined. I use that for the short sections

[@georgegouvas27]

braded line are used for areas that need to flex or bend around things that hard lines won't work .

[@albertgaspar627]

@@georgegouvas27 he did mention that, whether rubber or braided in the short sections going from frame to engine. The problem is, most "braided AN line" you find on a custom car is really just a sheath computer companies use to bundle their cables. the real insult is when you buy the complete package to install these things...there's no sheathing for the lower radiator hose! just the top one.

[@bluemule3891]

HI, you do not want steel lines from the high pressure pump to the injectors, or on the fuel feed to the high pressure pump, or in anything that makes big power, the vibration alone is enough to crack them. Think about every pro stock, funny car and a or tf dragster that you have seen, what do they have, steel braided, with Teflon, it will not break. And don't get me started on Wally. A flare for a rubber hose, and not barbed fitting, I doubt that would pass Tech. Blue Mule

[@thewholls7176]

Good video uncle Tony I had the same trouble with collapsing hoses awhile back except instead of being a fuel line. This was a brake hose and I wouldn’t say it collapsed, but it certainly internally delaminated after I did a brake job and I had crimped the hose so it obviously damaged the hose internally and created a check valve scenario hydraulically And the front brakes were pulling, but from the outside the brake line look perfect……!!!

[@cerial0411]

I don't run down a strip. But for the street once you run 3/8" nicopp its hard to run anything else. Use hose clamps with rubber insulators every foot or so and the proper angle flares for your fittings and don't think about it for several years. I also try to run sections of actual 1.5"OD copper tubing in the radiator hose straight sections to prevent collapsing and shed some heat.

[@salspitz177]

[@jsimmonstx]

Regular braided hose (steel or nylon braided) will start to decay after about 7 years with modern gasoline fuel (ask me how I know). I just ordered hose, fittings, pump and filter (almost $700 - sheesh!) to completely re-plumb my newly acquired 1964 Fairlane with PTFE steel-braided hose. The current fuel system is over 25 years old, and gas is starting to seep through the existing steel braided line. Right now, it's just fumes, but I'm sure it will eventually turn into outright leaks, and I have a Mustang that needs the same treatment in the next year or so. I'm honestly somewhat surprised that you used a piece of old junk box fuel line on a race car.Look at these life lessons you're learning, even at your advanced age. :)

[@elmerfudpucker3204]

For myself being one that suggested a rod problem, I took your original video info to truth, when you expounded on all the checks you made on the ignition, and pronounced it to not be the problem.

Yes sir, we live, and we learn. The cheap comes out expensive and of course we are always learning what to do and what not to do when it comes to this stuff. Some people have a use what you got mentality on using used parts so to speak and they are always having problems. But the whole bottom line is we gather experience and experience is something you just cannot buy. I put a turbo 400 automatic in place of a turbo 350 automatic in my pickup truck back in the seventies and a friend of mine who had a repair shop went through the turbo 440 transmission for me and I installed the transmission in the truck. Well, another buddy who was working for the fellow threw me some vacuum line for the modulator valve not new from the spool but some extra pieces that were kept around for such purposes as I needed. We got the transmission in and when it came time to test drive it the transmission would not shift properly. After some digging around my friend that had the shop just happened to check that line and it was plugged up with silicone. After he called me a "big dummy" I told him that my use what you got buddy had given me that piece of line to use for the modulator valve. Would have been better to have cut off a new clean hose from the roll Sometimes it pays to not reuse stuff and fork out the money for new.. We live and we learn. At least you finally found the problem and it just took some more time to narrow it down. Now let us see what the sledge hammer does.

😂Tony got bit on the ass by his own doing, throwing used parts on a car without inspection and this is what you get, I don't understand how you could mistake nylon for steel. Going cheap on your fuel system can be deadly, some parts need to be bought new, fuel line is one such thing.

I agree, generally. Something you may not have experienced yet personally, is loss of eyesight. I'm in my 70's and my eyesight is such I might not recognize the difference immediately in the hose.

Had fuel cell foam break down in a late model. The bits of foam plugged up all sorts of stuff. We thought we’d fought through it, but under load making laps it’d sputter out. Finally found the 90° fitting on the fuel cell had plugged up with foam. The pump could pull well enough under light load, but would starve under higher load. Sometimes it just takes working through the process. Can be more difficult with race cars when they only really want to mess up at the track.

[@spc_inv]

You can use a fuel pressure isolator and put a gauge inside the car

[@jsimmonstx]

I have an electric fuel pressure gauge in the car, and a mechanical gauge at the regulator.

[@gittnjiggy2]

You should only run teflon braided line Tony. I started throwing out all the old lines and parts that have anything to do with fuel, can't trust the old stuff anymore.

at 4:30 I thought the left side header pipe was your arm with a Ta-too LOL

[@crazeyspivey]

That line may have collapsed if your "air vent" at your fuel cell is clogged or the one-way valve is not working right.......cant get enough air into the tank, and the fuel pump will suck so hard so as to collapse the weakest line in the system.

[@taskmaster58]

We had to put a tag with the installed date on all our hoses and lines and depending on the type of line we put a tx'd date so that we would know when the line/hose was to be replaced.

I've seen the nylon braided lines and wondered if if it was just for aesthetics purposes

I dodged an expensive bullet recently. Bought aftermarket Derale oil cooler for my engine. It came with 3/8” hose to go from sandwich plate to cooler and back, wanted larger hose, bought from Amazon because it advertised 300 psi working pressure at 275F, for “oil, fuel, transmission fluid” etc, never used it, was going to put on this weekend. Reviewed the reviews. Quite a number of folks (with pictures/videos) showed the hose grew hard in 1 month, clamps couldn’t tighten, leaks/failures. Yikes

[@truracer20]

There is a chance that some top ring lands could be deformed and pinching rings. A leak down test, compression test or simply looking at the amount of oil smoke and blow by will tell you if you have an issue. But on a stock style flat top it's likely fine.

[@guyjordan8201]

Were you using that same fuel line with the slant-6?

[@94eg8h-t4]

I see this all the time on outdoor power equipment. Ethanol absolutely destroys regular fuel line in a pretty short amount of time. Even though it costs more and I don't need something rated for near the pressure rating I only run fuel injection hose on lawn tractors, lawn mowers, snowblowers, etc.

[@markwise9868]

Who could have imagined that a 20+ year-old beat to $hit fuel line of unknown origin would be the root cause the problem?! 🙄

[@johnmccormack3024]

There is a guy on KZbin that covered this exact topic. His name is Uncle Tony! I think that you found a collapsed fuel line on your Charger. Some people have all the luck. :) I am glad that you found the problem! Your patience will pay off. I love your troubleshooting technique. Work on one, and only one, problem at a time. This is a slow but effective method. Great way to keep ones sanity! I see a rematch with that crazy Australian and his modern German car! Thanks for the great videos!

[@mansonmydog]

Will there ever be a successful run down a drag strip???

[@tonycs-9]

Put a camera down the holes and look at the pistons and valves.

[@crazywickedcustoms7272]

Really Tony, you don't check your fuel.lines,that's first thing you check.

[@feelgoodhorizon4084]

i like stainless tubing with ptfe hose at the ends.
