My fuel set up is made up of all braded lines and fittings and they seem to love absorbing the heat of the motor and the exhaust. When I drain my gas its too hot to even touch with your hand! Ive seen the mini fuel coolers that you fill with ice and the small little fuel radiators. Any suggestions to what I can do to bring down my temps? I dont want to burnout my Fuel pumps. Do the small fuel radiators even make a difference? Thank you.

The fuel in the tank is hot because so much fuel is being returned to the tank from the engine bay. It's a consequence of increasing fuel pump flow. That's one of the reasons why the factory fuel pump runs at two speeds with the factory resistor system. Newer return fuel systems will run at 3 or more speeds. Returnless fuel systems don't have to deal with hot fuel coming back to the tank at all.

The reason the OEM's are concerned about fuel temperature is because hot fuel increases vaporization, which means more raw HC evaporative emissions and a potential for hot start problems.

I wouldn't worry about burning out your fuel pumps unless you are running Kenne Belle Boost-a-Pump or some other system which overdrives them.

Additionally, the first things to leave the fuel are the additives for raising octane (toluol, triptane, benzol, etc). insulate the lines in the eng. comp. Add a fuel pump controller - Aeromotive makes a great PCM one.
