i think you mount it after the stock one (downstream in the return pipe)
so that the stock one releases anything over 35psi but the new reg will regulate the pressure that is returned to the tank
best not go too high on the pressure tho, i noticed my fuelpump fuse got quite hot when i squashed the top of my stock reg down, to give 50psi

cheers mate your top help and whats an ideal pressure to run

should i t piece the vaccum pipe aswell

i would put the vacuum pipe onto the new prv and try 45psi, then check the fuse (if its hot, you might be working the pump too hard)

cheers mate love the drawing copying it now,did you put the vacuum pipe on the new one when you did yours

and did you notice a difference

i had it on my super s for a few years, and i think it helped to avoid leaning out at high revs, but as for gain, you would need to dyno it to make a comparison

fitted it straight to the rail today. Works perfect on about 43psi at minute and feels more responsive, cheers frank2 for the help really appreciate it

good boy! waste of time fitting it after the stock reg, all its gonna do is increase the pressure inbetween the stock reg and the new one. keep an eye on the fuel reg every now and then, the china ones have been known to seep fuel through the seals over time.

i beg to differ there, imo the pressure will be 43psi from the pump all the way to the new prv (the stock one will be held open).
for instance, if you blocked the return pipe, the pressure would be whatever the pump could supply (prv or no prv)

every car that has ever come into me that's had the stock reg still installed, and then removed has shown a fair bit of difference in a/f ratios, in one instance from 13.1 to 12.4 with the adj. reg still on the same pressure... it's made a difference from my experience anyway.

well at 43psi its very cool gets slighty warm but nothing more than slighty warm, and cheers turbo i may turn it up a bit more
