I've seen the question posted a number of times on here so I figured I would post the answer since I just spent a few hours trying to find one.
The GM and AC Delco Part number for the schrader valve and cap located on the fuel rail of 5.7 and 5.0 TPI systems is 17110854.
A general google search for the part number should pull up a number of places to purchase it from. Typically ~$25.00 - $40.00 new and includes the gasket and cap.
Mods so far: MSD Cap and rotor, MSD ignition coil, Accel 8.8mm ignition wires, Hooker Super Comp Shortie Headers, Flowmaster 3in catback, underdrive crank pulley, custom cold air intake, NOS wet 125 shot, air foil and a lead foot! no E/T's yet. ...TURBO COMING SOON...Other mods include keyless entry and remote start, and Sequential Turn Signals.
