How does the B&M fuel regulator suck?

How is it that the B&M CommandFlo Fuel Flow Modifier sucks? I have heard this before, but haven’t experienced it for myself. I found this info by searching, but I could never figure out why.

All I am doing is putting in a Walbro 255 in-tank fuel pump, and I need the regulator to slow down the fuel flow or pressure just a little. I want to upgrade my fuel system since I wil be using nitrous.

Any opinions or thoughts on this subject would be greatly appreciated.

Okay, take it that there isn’t anything wrong with the B&M regulator? WTF?

They can only raise fuel pressure not lower it.

Do you recommend that I go with another regulator? I mean, I want to put a beefier fuel pump in the mix since leaning a motor out would suck a$$. My factory pump is gonna bite tha’ dust, so it’s time for a new pump. I think that it’s the original pump. I am leaning towards the Walbro 255 pro pump. I have heard that the 255 standard won’t even raise the fuel pressure, of course this doesn’t necessarily mean that it won’t provide more volume.

On another note, I think that the AEM FPR will bolt right up to the factory fuel rail, and it will allow me to remove the little thingy on the end of the fuel rail also.

What do you think?

yea im planning a turbo and nitrous project and from what ive gathered the aem one is really good. if i were you i would do rc injectors,golden eagle fuel rail, aem fpr, b&m gauge, walbro 255 pump

Which walbro 255? There’s two of them. Will the standard Walbro 255 be enough, or will it be enough to piss me off?

i think itll be enough all my friends with 240 sx with sr20 swaps use the standard 255.
