rb20det fuel pressure regulators

[wantsansr]

got me a rb20det out of a 93 gtst. now my fuel pressure regulator is bad problem being i have 2 fpr's one is at the front of the rail and the vacuum line is plumbed in after the throttle body. the second is at the end of the rail and is plumbed vacuum wise before the throttle body. im assuming the one at the front of the rail is active during vacuum i.e. not under boost and the last one is for under boost. question being.... has anyone else seen this and do you have a part # for them so as that i can see if nissan can get them???? anything will help... and if you can confirm if my assumption is correct about one for boost and one not.

If you're running a more or less stock setup, dont even begin to **** with an FPR. The stock one is plenty good.

Some come like that, it may be a kouki/zenki thing. I have never been able to figure out what the determining factor was. Just cap the one on the back and stick you a new one on the front, problem solved.
