Relocating fuel cooler

08Monster · Oct 8, 2015

Has anyone relocated their fuel cooler? Like clean out the radiator for the fuel cooler coolant and actually run fuel through there and ditch the cooler under the hood and just have it air cooler instead of water cooled? Or put in a completely different radiator with a fan to run the fuel through it and mount it elsewhere? Seems like that would produce MUCH cooler fuel while cleaning up the engine bay.

elite diesel sells a nice kit

Like this? Big one is trans cooler, small is fuel. I've redone the entire fuel system, unregulated setup. The cooler is inline on return side back to the fuel cell. Removed fuel cooler and lines up front. Much cooler all around and simpler. Trans cooler works amazing also.

Yes exactly but behind the bumper.

You could probably mount it to the underside of the bed also, keeps it tucked up out of the way, and I recommend it installed on the return line

Why is that exactly? Is the stock in the return?

Yes.

Yes, the lift pump, hpfp etc all generate a good amount of heat, if you can cool the fuel back down before it gets to the tank it will prevent a lot of other problems. Especially when fuel levels are lower (recirculating the fuel faster)

I saw a 3-4 psi drop in pressure on the lp side before fuel cooler install and you couldn't touch the lines it got so hot (during a hot day). Post cooler install psi might move 1/2 a psi, and lines are barely even warm

This would work good too, same size lines and you can wire the fan into the pump harness ( if you still have the fuel temp sensor hooked up ) and when it hits the predetermined temp that circuit will power up and power the fan up instead of the coolant pump.
