I'm so frustrated right now. i installed a Raptor fuel pump because my Holley was leaking fuel into the electric motor and then onto the ground. well today i went out to start the truck because its not plugged in and was -6* here in chi-town and it started(barely). so i idled it up and went inside. Well i went out about 40min later to turn it off i had no fuel pressure. no clue why or how long it was without pressure. too cold and dark to look to see whats wrong. the pump has been on for over a 9 days with no issues today. i use fuel additive. dont think its gelled fuel. i'm so ******. Please post thoughts. oh and just to make it clear i'm not bashing the pump at all. i love it... when its working. i have never seen this truck idle smooth than it has with this pump.

 

Quite possible its a failed sender/gauge. do you have a mechanical gauge??

 

Could be your fuel has gelled up due to the below zero weather.

 

Maybe a fuse let go.

 

i have a mechanical and electric gauge
i added fuel treatment every tank
pump runs but no pressure

 

No leaks either

 

stuck open regulator???
