yeah it works fine. The reason I ask is bc this company at www.customcarbs.com that is going to custom build my carb says that the recommend not too, not that it does not work, but due to the high pressure low volume. I dunno, know very little about this stuff. I have a walbro 255 in it right now.

so your saying just install a fuel pressure regulator at the carb and hook it up to my stock fuel and return lines and be done with it?

 

Heck I'm keeping it N/A and trying to make as much power on a stock lq9 bottom end with ported l92s. If my FP is more then enough then that is what I will use. hell I guess I can just install a FP guage and watch it at wot, and if its goes to far down then i can install a inline pump
