need a little help with it

i got the gold piece where the old fpr went, but am a little confused. does a fuel line go from there to the straight pipe on the nismo fpr or the bent pipe?

and then whatever end isn't connected to the fuel rail goes back to be connected to the ccar right? the fuel return line?

looks like you bought or someone else installed the fuel rail adapter that allows you to use an aftermarket FPR. Take the gold piece off and bolt the Nismo FPR in its place...

If I'm right this is what is already installed on your fuel rail...http://www.courtesyparts.com/M..._Code=

the gold piece came with my fpr and when i took off the stock regulator that piece looked identical so i tried it in and it fit

but what you guys are saying is that the straight pipe goes in that hole for the fuel rail and the bent pipe is the return line?

its on a 25

just went out and checked and the hole is the same size as the end on the gold piece that has the screw holes on it, and the fpr deff doesnt go straight in, i tried both ends in and the hole is too big for it

did i maybe get the wrong fpr?

like a glove lol, had a problem with the bolts being too long because the cheapo doesn't cast as much of a spacer in the mani as the stocker or greddy one does but it also doesnt use as many bolts so you just go down a bolt size for each bolt ( in place of that one long one you use the next size down and so on) and for the very short bolts (obviously you wouldn't have any shorter bolts than the short ones) you use the 3 left over bolts from the fuel rail (it uses 3 instead of 6)

ill be able to say more when its all said and done, just wanted to throw on a replacement for the stock one b/c in my opinion its ugly

good to know...

Oh also I would turno the gold fitting around so that the fuel line that will attach to it will face in and not out.

The straight line goes to the rail. Curved line goes to the return. Mine didn't have directions either. If FPR is hooked up backwards fuel pressure gauge bounces like a banshee. Found out the hard way.
