a1000 pump
 

ok sooo here's my question does anyone feel thar 1 single a1000 pump could support 2 500 efi engines with separate by pass regulators?

I would have two separate smaller pumps for redundancy.
one pump fails you can still get home.

what pumps is everyone using for NA efi engine's?

I believe that is the pump I am using for my 598.
But I am north of 800 HP

I have an extra a1000 that I plan on posting in the swap shop soon if you're interested....if they are stock 500 efi's I think that pump is way overkill...whats wrong with the stock setup??

they have cams in them. every one says ditch the cool fuel. and to be honest it gave me nothing but problems after i did the cam swap. not to mention there a pain in rhe azz to service.
do i REALLY need a Marine rated pump?
i was looking at the holley in line for half the cost as well.

Mine is not a marine pump for what its worth..I didn't run the a1000 because I didn't want to upsize all of my AN fittings that I already installed for the fuel system...plus I have 2 tanks 1 engine so a return style regulator would have been a nightmare...I'll look up the unit I'm running and post it for you...very nice relatively inexpensive product and it has a built in regulator that can be ran as a bypass or deadhead

That pump will not support EFI ^^^^^^^
