Noticed i had a a line leaking right before it went in to the cooler. Found out it was diesel fuel, and fixed the line. Maybe this is a dumb question by what exactly is the purpose of running fuel through a cooler? Why would they need to do this?

Thanks for the reply! I guess that does make sense. I just wasn't familiar with that. Most everything I run is older than that.

If you trace the lines you will find that it is the return line,excess fuel picks up heat at the pump and is cooled before returning to the tank.Over time returning fuel would warm the fuel in the tank quite a bit.Must be a quite a bit of fuel returning to the tank.My 25 year old Deutz-Allis has this cooler on it.

With many of the newer engine and fuel system designs, the fuel is exposed to more heat due to circulation through the cylinder head or close proximity to the engine along with higher return volumes and hotter engine compartments. Fuel coolers are a must.
