Gen II fuel schrader valve location

[mrdougiefresh1]

Is what my index finger is pointing to the fuel schrader valve? It has a green cap and has a valve core inside it, but I've never seen one of these not on the fuel rail itself. I am wondering because I am considering running nitrous and am trying to find places to tap into the fuel system with little modification. Thanks.

That isn't it. IIRC, that's the vapor canister purge valve. The schrader valves are on the fuel rail....

Could someone post a picture of the schrader valve then? I have had my fuel rail off and did not see any schrader valve

Hmmmmmm....... Can't find one on the fuel rail picture..... The 2nd gen procedure for relieving the fuel pressure is to pull the fuel pump relay then run the engine until it dies....

Yes, that's a test port for the fuel tank vent system.

Not all gen IIs have a fuel schrader valve. One of mine does, and the other doesn't.

Damn, well I guess I don't have one. Second option is T-ing off the line that connects the fuel rails. Probably a more reliable option anyway. Thanks for the quick responses guys.

You could always use the OBDII pressure reading, unless it is the pressure sensor that you don't trust.
