How much HP can this safely supply? It is stock fuel lines and Motron 60lb injectors.
I've always thought the in-tank 255 was good for 600rwhp in a N/A or Nitrous setup, but how about for a FI setup?
What can the 2 pumps together handle? I am assuming this is more than I will ever need for 550-650 rwhp.

Hey guys.. Just checking the site and ran upon this. What intank pump would you guys say would be great "as a direct bolt in" for a STS rear mount turbo with 625 rwhp in a LS1 F-Body? Thanks..

Just one ??? I may be calling you. I have a LS7 motor out of a wrecked ZO6vette, that I installed in my 1932 pro street truck. Right now I have a weldon 600-A external pump. I think it is right on the border as being enough pump. All I have done to the motor is a set of headers, and Speartech did the computer. It is suppose to have a power tune installed in the PCM also. Based on this. I would guess the HP around 550 maybe. What do you think? will the 600-A be enough? or should I have a intake pump fit to my fuel cell? If so what pump, and is that something you can do? I also have a weldon bypass regulator, with 6 AN feed from the pump, to the regulator. An a 6AN return. I have a 10 AN from the cell to the inlet side of the pump.

Yes it is. Do you think I have the bypass regulator in the wrong place? It is just before the driver side fuel rail. I bypass right there, just before entering the rail. Someone said I should put the regulator at the end of the passenger rail. That way the fuel goes thru the rails first. But weldon told me to hook it up the way I have it.

It is connect to the fuel pump relay that speartech supplied with the harness. The pump only pulls about 6amps. I ran #12 from the relay to the pump. Not sure what speartech ran from the harness fues block to the relay. So where do I get the passenger side fuel rail with a #6 AN that will go to the regulator?
