Cheapo Fuel Cooler
It's getting hot here so I went to a local boneyard and purchased a trans cooler for $10 and installed it so that when the motor is running, air is being pulled past this cooler.
I bought a cooler install kit, hose & clamps at the auto parts store.
I trimmed all the existing mounting brackets off the cooler since they didn't fit anything on the truck.
There is a stud and a place for screwing in a bolt like maybe a factory extra heavy duty trans cooler in the same area.
I cut the return line just where it gets to the frame rail and added enough fuel hose to get to the front of the truck. Ran the hose across the frame, behind the brake lines and over the inner fender to the front.
After I finished the job and 1 hr. test ride and it does work but not as good as I'd hoped. The fuel gets cooled to ambient sure enough and the fuel tank is cool but there's still a bunch of heat soak from the motor I guess. I can now hold my hand on the VP top until I get bored but it's still very warm.
The good part is even if I get stopped in traffic, the fuel will be cooled as long as the motor is running.
Just for general knowledge, I timed the flow of the return line....a little over 3 qts./2 min. @ idle and 2qt./min. @ 1600 rpm stationary....lift pump showed 15 psi. Posting some pics in my gallery.

Did you time the flow with the engine shut down but the LP running?

When it gets cold, I'll bypass the cooler

The engine was running but it might be interesting to see if or how much it flowed on the starter bump.
