Ok this is the first one i've done, i've got a eg with a b16a2, just installed a b&m fuel pressure gauge at the filter, reads about 45psi while cranked and about 20 or so when its turned off, is this normal with the stock regulator? I'm about to install the b&m regulator so was wondering what kinda fuel pressure i should aim for with i/h/e. any help or advise would be appreciated.

 

before you go even any farther may i ask why you need the regulator? i have seen more bad than good with it.

but the fp does drop while off, there is a check valve in the pump to keep rail pressure while off, not always operating pressure.

the stock reg is fine, technically the fueling should be made up through the injectors, not fp.

 

well since i've already purchased it, couldnt i just put it on and keep it around where its at now

 

if its the clamp on type, i have never gotten one to seal properly.

if you want to put it on, have at it. i just think there are many better ways including keeping your stock reg .

but thats just me.

i had the vortech version, just wasnt purple, and it never held vacuum to allow me to set base f.p. correctly.

 

yeah i'm kinda cautious seeing how i got to cut the factory one, think i'm gona pick up a regulator from a junk yard and cut that one and if it doesnt work i still got the stock one

 

damn i've been lazy, just stuck the factory fpr and forgot till today i took out my fuel pump to discover a walbro high pressure 255, maybe thats why, a little over kill for my stock b16 i would think
