    Default Electric Pump Draws 20 AMP?

    Why is my Holley Blue drawing 20 amps? Wired it correctly per the help of you guys with a relay and switch..but I have to run a 25 amp fuse. It should only need say a 10 amp fuse max..it wants to get hot..thanks

    Are you running fuel through it? If your just testing, the fuel helps cool it down. Make sure the shaft is spinning if one of the vanes lock it will draw a huge load

    dead headed...same location for 20 years..I know we've covered this before but not the 20 amp issue...also because it's dead headed that's the reason it is drawing 20 amps instead of say 4-5 amps?? thanks

    Deadhead isn't ideal, but Should still work. Is this the pump you already overheated before?

    Does the output pressure start falling when current draw start to rise? also is this with the engine running? How long are you running the pump before it starts to get hot and pull a lot of current?

    Somethings wrong with that pump/motor... I wouldnt keep drawing that much or you are going to be replacing all your wiring and everything when it all melts.... try another pump.

    The pump pressure starts to die off, gets hot and stops..don't know about the current draw..when the engine is running on a hose the fuel pump is drawing 20 amps....does not run over say 20 minutes before it stops......and also just got off the phone again with Holley..he said maybe the clamp is too tight which it's not..

    Is it a marine blue, or automotive blue?

    So...I don't know what your budget is - but I went from a Holley blue with a bad attitude to a Holley HP 125 and it has worked great.

    As for the issue. The only thing I can think of that would spike the current like that is a "stuck" motor. If it's spinning freely I can't imagine what it's problem is. This'll sound dumb...but can you verify the voltage going to the pump?

    he just redid the wiring with the correct relay setup.


    When you run it for 20 min is it just running on the trailer? It sure is sounding like its a junk pump. I said in the last thread that the holley pumps are so problematic and just not very good. They really give electric pumps a bad wrap! I don't remember if you mentioned or not, but do you have any prepump filters? does it pull from both tanks at one time? have you checked your suction pieces?

    do this....Pull the suction hose off the pump and get a 5 gallon gas can full of gas and put the feed hose directly from the pump into the can. if it still overheats after 20 min you know the suction side of your fuel system is good, and the pump is not. if it stays cool and has no issues, you have a suction issue somewhere, and finding it is the next step.
