I have a 99 GSR and i'm boostin it, i got an HP Racing manifold delivered today and im installing it tomorrow, but not installing the fuel rail they sent. I was wondering if my stock fuel rail can support the RC550s that i have, and if the RC550s will even physically fit in the rail. I am only going to make 300whp or less...im not going outrageous on my build!

I don't know whether or not i need an FPR if i just use the stock rail and fuel pressure. Im not going to raise the fuel pressure, but w/ a Walbro HP fuel pump, would my stock FPR and rail handle it?? I don't want to go cheap, but having said that, i also don't want to get something i'm not going to need.

Any thoughts?? And who has a similar set up on a GSR or likewise that is using stock??? Thanks guys!!

 

ive run rc 550cc on stock gsr fuel rail before...no problem here...and everything fit pretty good

 

alright thanks a lot!! I didnt really want to buy an aftermarket FPR for another $100.....and especially if i didn't need it....thanks again!
