Damn that’s a lot of work. I fixed vapor lock in my 62 impala for about $50. Purchased return hose and 3nipple fuel filter before the carburetor. Also used some heat shield wrap over the fuel lines in the engine. I drilled into the filler neck so I didn’t have to clean up or mess with the gas tank at all. I live in texas with 100+ degrees all week. I drive my old school every single day:) after I did that fix my car never had any problems after that. I even went to car shows driving for 4+ hours with the car on and sitting in the summer :)

I've been dealing with ethanol issues on all the big 3 for years. The first thing to determine when having fuel issues: is the issue not enough fuel in the carb, or too much fuel? Not enough = vapour lock. Solution is electric pump and return line. An in frame Edelbrock works well. That set up in the Impala looks extremely expensive and prone to failure. I had a ford 460, 4100 series Motocraft carbed motorhome that worked flawlessly even climbing mountain passes in B.C. at 37 degrees celcius, loaded. NEVER percolated or vapour locked. And it had those two things. Too much fuel/flooding = heat soak/percolation. The solution so far is a return line port as close to carb as possible, insulating lines, and as tall as possible Phenolic/wood spacer under carb. Also that big, hideous air cleaner is going to trap a lot of heat at the carb!

Hey guys, I am a small engine Mechanic - I`ve had the issue a few times of steel gas tanks needing holes drilled into them sometimes and I`ve come up with a 100% perfect solution to keep EVERY little speck of that metal debris/shavings from entering the gas tank - and THAT is to use one or several very powerful Ceramic "Rare Earth" magnets around the area where the hole or holes are being drilled, and you do NOT need to be in the awkward upside down position (and get a possible injury to your eyes and HOT shavings to skin areas making you jump from the burn reaction, possibly messing up the hole) to do the job. When finished with your cutting, drilling, de-burring?, simply *Slide* the magnet to the hole you just cut and remove the collected shavings. Another added suggestion would be to have a "Secondary" magnet set directly attached to the outside bottom of the tank directly below the drilled hole JUST in case SOME does slip past, when done?, you can (like " I " do) is to clean THOSE shavings at the INSIDE bottom of the tank where (IF ANY) that magnet was placed?, use a wood stick/Dowell with a Q-Tip like bundle on the end of it (DON`T use a telescoping magnetic pick-up tool to do this, it does NOT pick up those shavings because the area is MADE magnetic by the stronger magnet and chips WILL stay there) with a petroleum based lubricant to wipe/pick up any shavings after removing the magnet from it`s location. Hope this solves SOME headache`s with that issue.

@vintagethunderbirdrepair94262 жыл бұрын
Hey Eric, great video. I restore old Thunderbirds and have had to deal with the vapor lock problem quite a bit lately mostly because of the crappy gasoline that is available today. I live at 7000 ft altitude so this altitude just adds insult to injury with regards to vapor lock. The problem you describe in the video, "not being able to restart the car after shutting it off," I have found more attributable to the gasoline boiling or evaporating out of the carburetor while it is sitting there. For example, you go into the market and your car is sitting outside for 20 minutes or so and as the engine heats up from being shut off and no more cooling system action, the gas in the carb starts to boil and evaporates. When you go to restart it you have a "too rich" issue because of the excessive fuel vapors and the heat. I push the gas pedal to the floor and crank it until it starts, works every time. I do not pump the gas pedal. Pushing the gas pedal down to the floor and leaving it there until it starts opens up the throttle plates in the carb and allows air to rush in creating a lean mixture and allowing the car to restart. The vapor lock problems I have experienced with the Thunderbird while driving is (390 or 428 FE engines), loosing power, bucking and surging, acting like it is running out of gas, not being able to reach speeds higher than about 40 mph, and all of the above when going up any kind of an incline. For me and my Thunderbirds, its never a restarting problem, its always a "while driving" problem. The cure was exactly what you did in your video with a few exceptions. You put an in tank fuel pump which Holley recommended as the number 1 fix. On a 1966 Thunderbird for example, the gas tank rest against the trunk floor on the top and back side. The fuel sender is on the front side facing the diff. Holley said that you need 3" of clearance between the tank and trunk floor to use their in tank fuel pump so that was not an option for me. The next best thing was to use an inline electric fuel pump as close to the gas tank as possible and level with the bottom of the gas tank. So I installed the electric fuel pump right next to the gas tank and level with the bottom and I ran a return line from the front of the car back to the gas tank via a Holley supplied regulator, and used the original fuel source fitting on the sending unit as the return. From the regulator back, I used steel fuel line because it does not warm up there like in the engine compartment, there is nothing to heat the lines up. In the engine compartment, I used fuel hose and I insulated it with thick foam insulation, the same stuff you see around water heater pipes. I eliminated the mechanical fuel pump completely. This worked out great and cured any vapor lock issues. The customer drove the car over the Rockies on Interstate 70 and went through the Eisenhower tunnel at 11,000 feet with no issues while using 91 octane pump gas with 10% ethanol. They also drove around Utah, Nevada and California in 100 degree weather with the AC on the entire time. They had no issues what so ever. You can view the video I made on how I did it here kzbin.info/www/bejne/q3jEfaivrNiIZrs. Thanks again for a very informative video.

My 69 camaro with a quadrajet has a return line to the tank from the factory. GM had this issue in the 60s and quadrajets are very sensitive to it. If someone wants to stay original this is the easiest solution. Just add a fuel filter with a return line and a 1/4" line to the tank and use a sending unit with a return line on it or tap in a fitting to the tank.

I know this video came out in 2016 but Here's another tip i picked up back in the day in a issue of hot rod magazine: 101 tech tips. If you have a metal gas tank prep the metal surface for primer / paint . Used high temp header primer and paint with the ceramic in VHT or dupli color . But use the header aluminum paint. It will insulate the tank from heat coming off of the motor / car / pavement and keep the gas cooler. Also if you use a mechanical or electric fuel pump always use a vapor return line to get rid of a lot or all of vapor lock.

Seems like a lot of money and work for something that can be fixed for about $25. Get a fuel filter for an 89 Grand Wagoneer and install it between the carb and pump. Run a line (preferably steel) back to the tank and attach it wherever you want on the tank. Many different ways this can be done. I daily drive a slant six dart with a mechanical pump on normal 87 octane ethanol crap and never have problems. And if you know where the fuel pump is on a slant and how the fuel line is run on one, you know the pump sees zero air flow and the line is less than 1" from the exhaust manifold. No destroying a good fuel tank, no regulators, no easy to puncture hoses and no electric pump with shoddy wiring to fail. Works every time.
