Im using an aeromotive a1000 external pump, with the stock tank sumped. 10AN tank to pump, 8AN pump to filter to 1/2" aluminum hardline, then 8AN to the Lipp rail. Aeromotive FPR. My engine is a couple weeks from being built. So I can't comment on how well it will work. I probably have $1500 - $1800 into the fuel system.

Whats the limit that the a1000 can run up to? I see it's much more expensive than the walbro.

800hp forced induction. 650whp, Duane has one, he is at 660whp. Walbros I believe are good for 500whp, I think they run out around 550whp, but I could be wrong.

Sounds good. I guess I'm going with that one. Thanks for answering that question for me. It saved me some research. Lol.
