Depending on where u live in US the ethanol helps create vapor lock also # Older type vehicles were not designed to run on said fuel but thankfully we can address this common problem.
Thanks. Same problem with my 77 Midget. Cooking fuel in the rubber fuel hose. Will line the hose with the heat protection, and plumb the filter up to the return line to the fuel tank. Someone did a partial emissions delete on this car, and neglected to complete that circuit.
I owned the same van but it had a different fuel problem due to the location of the tank to the exhaust pipe. It was a really cold winter here and water from the fuel tank would freeze solid in the float bowl. After investigating the fuel tank I realized the exhaust pipe was really close to the side of the fuel tank heating up the tank. Then when the tank cooled the warm moist air inside the tank would condense into water. And the water would freeze solid inside the carburetor.
Hi, I'm from England and I have a similar problem with my car. It's interesting to note that as cars became lower the carburettor had to be closer to the manifolds to allow a lower bonnet (hood). With pre crossflow engines like the one in your van and my car the carb would get hotter resulting in the fuel boiling especially with modern petrol (gas). I've made a heat shield under the float chamber that I'm hoping will overcome this annoying problem. I've also fitted an electric fan on the front of the rad with a manual switch that I can use when stuck in traffic. I haven't had the opportunity to see if these have cured the problem but I'm also interested in the three way fuel filter you're using. I'd like to know if it would work if the mechanical pump was retained?
Wow, thank you for your support from England!... I was told I should use a spacer under the carb to give it some space but by removing all the rubber fuel lines under the hood and using the filter with the return to the tank I am having no more issues. I would say the filter would work fine with the mechanical pump but I like with the electric pump because I don't need to crank the engine to get fuel to the carb as the electric just starts pushing as soon as I turn the key... Thank you for your comment and I would love to see the heat shield you are talking about.
@@Rob.Ingram I have a spacer between manifold and carb which was fitted in the factory. I thought it would have been original equipment on most post war cars although I do have a car from 1949 that just has a normal gasket but I've never had any issues with that one. I would send you a picture of my heat shield but I'm not sure how to do it on CZcams. If you're on Facebook I could send it via messenger. I'm not very tech savvy but I expect my grandson could do it easily!
Both steel rubber lines absorb heat but the steel dissipates the heat faster whereas the rubber will swell and hold the heat longer. Maybe they both would be fine in the thermal wrap but steel is always better where it can be used.

Emissions... the word makes me sad... LOL
You explained it so well I even feel like I could do it loved the video
Thank you Aunt Sheila, and I have no doubt you could do anything!

Wow, that would be a fun problem to track down. Where do you live?
@@Rob.Ingram Fort Payne, Al on Lookout Mtn.
@@LkOutMtnMan wow, it can get cold up in the mountains, ours smokies here in Tennessee can get a bit cold too.
Thats a sealed gas cap correct ??
Thats why u have a ext vent on tank ?

I don’t have heat soak but my gas cap seems to have a vapor lock , I did change the open end from another truck ,, did I hook it up wrong
There was a little straw like chamber in the neck
Metal fuel line would have more heat issues than rubber line. Hose protector over rubber should work better than over metal.
Both steel rubber lines absorb heat but the steel dissipates the heat faster whereas the rubber will swell and hold the heat longer. Maybe they both would be fine in the thermal wrap but steel is always better where it can be used.
@@Rob.Ingram It will certainly last a lot longer.
