Holley Blue style Electric LP - How Hot??

[Chief915]

I finally got around to installing my extra fuel filter and HO lift pump last night. No issues, no leaks, and the truck runs a lot better at full throttle. Pictures will be up soon.

My question is this.... How warm should the motor on the LP get? It's a Holley blue style, diesel compatable pump. After about a 20 mile drive I got under the truck to check for leaks and such. I touched the motor on the pump and it was a lot warmer than I expected. My infared thermometer says 102*, the "pump" end of the setup was cool to the touch, just the electric motor was 102* F.

The FFM heater heats stuff to 140 degrees. And the air temp out here is 118 degrees. Your pump is running colder than the air temp out here... So you really have nothing to worry about.

The ambient temp last night, here in SE GA, was about 75ish while I was seeing 102 on the pump motor. I wasn't really worried about the fuel temp, I know it gets warmed up at the FFM anyway. I was talking more about the temp of the electric motor that runs the fuel pump, it was 25 degrees or so warmer than ambient.

I didn't get the feeling that was a problem or anything, I just never paid any attention to how warm an electric motor on a fuel pump gets before last night.
