what is the stock fuel pressure set at? two questions tho i ask this because i got a new adj fpr today but its not the kind that bolts to the stock rail like the AEM or B&M. it has its own gauge which i tested and the gauge does work. it has two barbed fittings almost like an FMU but im wondering where do the lines hook up to? this isnt the one i have but the fitting locations and style are very similar






it almost looks like the line going up to the fuel filter connects to the fpr but that wouldnt make any sense cuz then how would the fuel get filtered? if that factory regulator stayed in place where would the vacuum line go?

Looks cool, how much was it?

 

well that aint the one i got but the one i did get was like $70 shipped and the damn box it came in was all in jap and it didnt come with any instructions

 

lol ok well how do i do that? seriously i looked at the car and the regulator and it just didnt make any sense, i must just not be seeing something right

 

Buy a shop manual

in the case of an FMU you would leave the stock reg in and cut the fuel line from reg to the main return line of the cars hard line

so does that mean i have to cut the line and put a T fitting in the line that comes up to the stock regulator?

that would solve the issue of that barb/line but what about the other one?

 

i had one of those but i had to get rid of it cuz every time i let the car sit for a while it would hesitate and not want to turn over, so i bought a b&m, much better.

 

hmmmm what do u think may have caused that? u think i should just ditch this one and get a B&M? does the B&M allow for use of a pressure gauge?

 

Mount the Fuel pressure gauge on top of the fuel filter ...

 

in place of the banjo bolt?

 

Yeah, usually they come with a banjo bolt that has a threaded hole in the top, which is where you screw in the pressure guage.

 

well i did just replace my fuel filter and the banjo bolt did have a threaded top with another bolt that went thru it so ill try that idea later today, hopefully the gauge will fit

 

if the one you have doesnt fit ... i have the B&M FP gauge it was like $20 or something .. it fits perfect

 

that bolt that goes into the banjo bolt is real small and this gauge was way too big to go right in there

where did you get your B&M gauge so cheap?
