hello
today I had given to me a new " Aeromotive 11106 Aeromotive EFI electric fuel pump " fuel pump

I have a evo 1 that currently makes 419whp
and is ready to make 550ish

question is what pump would fit my set up better ? or what pump would you recommend that I run ?

the areomotive pump ? OR the walbro 255 /w rewire that i currently have in my car .. and no its not a HP walbro.

and IF i ran just the areomotive inline what would be the best way to pick up fuel from the tank ?

You could run them both. Get the in-tank Walbro to feed the inline Aeromotive pump further downstream closer to the engine. If you just want to run the inline, you can run a pick-up tube down into the sending unit and the pump no more than say 2 feet from the tank. If the pump is self-priming it will have no problem. That's how my fuel pump is setup. Inline at the back with a pick-up inside the tank.

FWIW I ran 135+ mph in the 1/4 on a single regular Walbro (not the HP one) with a rewire and 1000 cc injectors.

That was pretty much the limit of the single walbro.

Now I am running one of these Jay Racing PT341 intank:

This pump is way better than any Walbro, IMO is all that 99% of DSMer's here will ever need for their goals.
