PRVR is for fuel temperature. When car is hot and you shut it off, fuel is just sitting in fuel rail under pressure and it gets heated up by hot motor. When you start the car after a few minutes after hard run, its hard to start because the fuel is too hot. Its the general consensus here that PRVR is a piece of shit and its not needed. There is a line that goes from plenum to prvr solenoid, and from solenoid to FPR. (FPR is fuel pressure regulator its right next to metal fuel lines). So to bypass prvr, just plug that line that goes to prvr directly to fpr instead. This eliminates yards of tubing of potential boost leaks.
