Hey Guys,
was doing a search and came across this thread. I to was looking for an aftermarket cooling system for my fuel set up. Was going to go w/ the conventional fuel cooling like what you guys are linking but came across this beauty at SEMA show in Las Vegas. Company called S-Max intercoolers made this piece and its actually what you may need.
Its a surge tank with a cooling mechanism. owner of the car is Dave, he works w/ Smax and he explained to me its mechanics. I know there are alot of things going on in that trunk (believe me it was gorgeous in person) but if u notice 2 -4 an lines on the side of the surge tank (one on top and the other on bottom) those are actually inlets an outlets for Co2 (thats wat they use) or any cooling agent you want to use to help cool the fuel in the surge tank.
seems like i can post some more good information on this... I'll give Dave a call tomorrow to see what other information I can give... for the mean time... take a look at this beauty! (cooler on the right is for the diff)
