I'v seen a few fuel coolers, and as hot as it is here in texas in the summer. I'm wondering if it might be a good idea.. I know my return fuel gets pretty hot because after i turn my car off, i can here my tank popping because its contracting and expanding. which i know also might be the tank vent. But will I get any benefits cooling the fuel? Especialy if it IS pretty hot?

 

Almost all of the fuel coolers that I have seen are for track use. The line comes into the container and curls around, then exits. There is room for ice in the middle.

The lines themselves act as a cooler...you can try wrapping the lines if it becomes a problem...and then only near the exhaust and engine compartment.

It usually isn't an issue with a return line and high pressure (TPI included) applications.

 

breathment,

I copied and pasted this from my thread over on the history section.

"Drove car around town with my son and wife. Went 32.5 miles for the evening. It was awfully hot and humid. I heard sounds when I got home like the gas was so hot in the fuel tank it was boiling other that that noise the car ran great."

What I am getting at here is that the muffler is right below the gas tank and when its almost 90--100 degrees out and all the heat is rising up from the muffler, that fuel tank gets awfully hot just cruising around. Take the gas cap off when it is this hot and you get a very big whoosh. The thin metal shield they put right above the muffler does little to keep the heat off the tank. It seems like they are directing the heat up and around the fuel tank.

A fuel cooler in the summer time sure wouldn't hurt anything.

If you ever get vapor lock in the tank and the pump won't pump the gas, you have some big problems.

Vapor lock usually happens around the engine compartment and hence, that is what I thought we were talking about.

Sure, a fuel cooler and wrapping lines wouldn't hurt...just like a 502 dropped in wouldn't hurt either...it comes down to cost/benefit and unless you are having real problems, don't worry about it.

 

well, the sounds of the tank expanding and contrasting kinda scare me.. as they are enough to set off my alarm.. and be heard from quite a distance.. but i'll replace my tank vent and see what happens, as i think that is the problem from what i'v been seeing at that boards.... maybe i need a fuel temp guage..

 

That sounds exactly like a fuel tank vent problem...the expanding/contracting is from the fuel pump pressure....

Even on hot days, the exhaust is sufficiently cooled down at the muffler that vapor lock at the tank should be a non-issue...

Good luck...
