Where is the fuel pressure regulator on a 1997 Chevy 7.4 vortec?

The fuel pressure regulator is located on the back of the intake manifold, more towards the driver's side, next to the distributer. The Only way to access it is to remove the upper aluminum intake plenum. It's kind of a pain, but it is necessary. There is a rubber vacuum hose and two bolts that attaches it to the back of the lower plenum intake. While you're in there, replace that rubber hose also. Five-O motorsports sells Bosch injectors that are far superior to the stock Delco ones that ALWAYS leak down. You're in there already, so might as well do the job right the first time. Also a good time to check your cap and rotor. Don't try to re-use the plenum gaskets. Hope this helps.
