Ok, my fuel is getting hot. Still working on why, but mean time I want to be able to drive my only car.

So, will a "fluid cooler" such as this one http://store.summitracing.com/partde...5&autoview=sku
be able to handle the fuel pressure???

I am very tempted to ****** one.

Your fuel system recirculates excess fuel back to the tank so it can cool. I'd have a hard time imagining how it could get warm enough to have any noticeable effect on performance.

My tank is getting heated up pretty dang hot. So, I am exploring some options.

Apeiron

Even still, on an FI car, is it going to matter that much that the fuel is a little warm? It's not going to percolate in the bowl or vapour lock like it would on a carbed car.

Not worried about vapor locking. I am more worried about having a tank that I can't touch because its so hot. Thats all.

Thanks for helping thoug.

So there should be no worries about hot fuel in a TPI? I was debating on wrapping a bit of my fuel line since one of my exhaust pipes runs within inches of it near the rear wheel.

too hot might not be a problem, but cooler should realy help, think about it.

so after a drive i cant even touch my intake on the top, and i have a tb coolant bypass to boot, imagine if my iat reported 210* air was then cooled by say, 70* fuel? would this not be handy especially right at the port in the few msec before combustion? besides think of your injectors sitting inches from your heads, resistance goes up with temperature, so cooler fuel cooler injectors, probably a good move.

Apeiron

In those few milliseconds, a charge of 70 degree fuel might cool your 210 degree intake air to about 209.9 F.

True this, true that...

I just wanted to keep my fuel cooler. Now, my thinking is mounting the cooler before it goes to the tank. Sure, the fuel will be hot by the motor, and trying to fix that might be redundant. HOwever, if mounted closer to the tank it would cool the fuel at a higher rate (higher than 209.9 LOL). Cooling the tank would be the most ideal since it sits right above the rear end and exhaust which both tend to get hot. Touch your tank after a decent drive.

Ya.

Worry more about the temperature of the intake charge, not the fuel.

an old hot rodder trick, well not so old 80's i think, was to put dry ice in a canister which the fuel lines went through, before drag racing. you don't see them anymore,, nuff said.

i agree about IAT, not so much you can do on a tight budget if you have a t/a though. i think the ratio i read in the accel book was every ten degrees is roughly one percent more output, theoretically i could gain about 21 percent power if i could cool my IA down to 100*. the coolest i've seen it was hood open, motor running, 160* with coolant about the same. my plenum gets friggen hot!
