Help can any one tell me where the fuel pressure regulator valve is located at. Got It with bad vavle when I got it 02-09-10 Got it home tonight and off the rollback truck. I put new fuel filter on it with no help on 02-09-10?I think it is in front of pletum {intakemanifold}. What is the vavle on top in middle of pletum has wires to it. Thanks guys

 

I would really suggest you get a service manual of some kind for your truck. If you are going to crack into the fuel system like it looks you'll need it. If your engine is a Vortec (looks like it) the fuel pressure regulator is under the upper intake plenum. What exactly is wrong with your truck? Throwing parts at it (shotgun troubleshooting) might eventually fix it but finding out what's wrong and fixing that item is a lot easier on the wallet.

 

You can also search the forum. There is a lot of information about the CPI FPR around here. Including how to change it (tech article diy section).

 

The FPR is under that thing you talk about with the wires on it... Go read the posts farther back as there is about 10 of us last month that had these problems to deal with... Do a forum search for "CPI vin W" and see what you find.
