Thread: Returnless Fuel Pumps

  1. #1

    Default Returnless Fuel Pumps

    I was curious if anyone has used any of these returnless fuel pumps from Aeromotive or Holley? And will they perform as well as a return style setup?

    I noticed these produce a set 60 PSI fuel pressure. Would I need to run a regulator with these pumps even though itís returnless?

    FYI this will initially be used with a 200hp engine eventually to be replaced by a 400hp engine later this summer. Not sure if that changes anything.

    They have an internal regulator like many vehicles these day that run only one line.
    So you don't need another regulator.
    Disadvantage is you can't change the pressure at all.

    Thanks Gary - any concerns with running 60 psi thru the atomic?

    I've seen as low as 25, and as high as 85.
