I have a couple of questions about his pump for you guys. What RWHP can this pump hold up to? Would I still need to run an inline pump with it? I plan on making approx 500-600 RWHP.

Thanks,

Matt

 

I am running that one with no problems so far. It does support 500, but I would want more pump before 600.

I am running the Walbro 255 inline and Walbro 255 intank and don't think I'll have any fuel problems. I've heard it can support up to around 600hp (flywheel I guess?).

The walbro 255 is a great pump. I'm not sure though it might be either the GSS340 or GSS342.

Good luck
Tim
