Electrical and Mechanical Fuel Pump

817 Views 2 Replies 2 Participants Last post by  Cardfan16
I would like to use a mechanical fuel pump along with my eletrical fuel pump as back-up. Does anyone know if there issues with using the mechanical and eletrical at the same time? Actually, I would probably use the mechanical most of the time... Holley in-line eletrical pump.
Thanks for the help!

That's probably not a good idea. The mechanical pump would have to pull fuel thru the electric pump and they're not made to do that. Why do you want to run both? What is the combination? Is it street/strip? If street-only driving, run the mechanical. If you want max power for the strip, run the electric. Either pump will work fine for the street, just make sure that they're rated properly for the amount of fuel you need to flow and use a filter! Good luck!
