Fuel Cooler and proper fuel Temp?

[Fordcrazy]

I just installed my new Spartan tuner, and it is awesome!! I went from 8.2 mpg with 6600 in tow, to 17.8 with same trailer in tow. Without the trailer, 19.8mpg, I am the happiest guy in the world right now!!! The tuner also is telling me that my fuel temp is running at 164 degrees and the warning starts at 140 degrees with high temp warning set at 160. Does anyone know what the proper fuel temp is supposed to be for this unit?

should be around 118-122( unless high ambient) check the coolant in your cooler it is on the driver side with a little silver cap it has a sight glass. you probably have air in the system it can be bled with the allen key to the left of it brass let it run and bubles will come out

the temp will always be really high when started because of heat soak
