Nismo FPR issue

Post by **Bioxide02** » Sat Jul 08, 2006 2:45 pm

So, I just installed a nismo FPR today on my RB25 series one motor and I am running into some issues.. So, I set the fuel pressure at 43-44 psi without the vaccum hooked up to it.. Then I tighten down the FPR and go for a drive.. After driving it for about 10 minutes or so the pressure drops down to 40ish psi without the hose on...

Did I just recieve a faulty nismo FPR or whats going on? Anyone ever had this happen before? It sucks when I was driving it at first and the motor started to ping really bad.. And I looked at the fuel pressure and it was waaayyy to low.. This sucks.

Yes, I am.. Today it didn't drop at all... But I didn't get to set it at the 43-44 psi range.. I just set it at 45-46ish and it stayed there
