    Hey folks,

    Going through the endless options of efi pumps, can anyone show me theirs and any issues with installation.

    i am aware of aftermarket efi and tank in one setup, but shipping to australia is a bit crazy price wise, other than holley is there any other direct fits, im okay with mounting one inline as well

    I have read where some used the holley drop in to the original tank , and it was also returnless , so that makes it ever easier , hopefully they will post what they thought of it.

    Holley 12-304 is what I'm using with my ProFlo 4 setup, no problems so far. It seems to run 2 - 4 lb over the regulated 58psi but this has not been an issue.

    i actually pulled the mechanical pump out today, it had a feed line to it, but alongside it was another line that was blocked off, im assuming this is actually a return line to the tank, not totally sure on that but would be handy if it is, if it is i am guessing the replacement mechanical pump did not need a return

    Yes, no return line required, I spoke with Eddy tech about this. The return is built into the pump.

    Cool, how do you know its running more than advertised, have you got a pressure regulator installed as well?

    Yes, the ProFlo 4 has a pressure sensor. No regulator installed, regulator is built into pump. Mine just runs a bit high.

    OEM.
    5th gen camaro like a 2010 Camaro SS fuel pump should be available there for a similar global platform?
    Fabrication is probably available there but vetteworks sells the mounting rings in both steel and stainless. The website isn’t that great.. hard to distinguish between 4th and 5th gen

    Might have to do a sump to get minimum depth. Run 3 bar fuel pressure regulator, he sells those too. The regulators are out of a vw or common euro model, again probably a global platform.
