I removed the shrader valve (the valve stem in the fuel pressure test port on the fuel rail) from my fuel rail a few years ago to mount a under hood fuel pressure gauge. I am trying to trace down a fuel smell and it is coming in the area of my fuel pressure gauge so I want to remove the gauge and put a new shrader valve (valve stem) in. Does anyone know where I can buy a fuel safe shrader valve like the one that came with the car? I am worried that if I use a valve made for tires the fuel will eat away the seal.

 

I doubt that the gass will eat the seal as it made to stand up to liquid calcium, and that sh(t is way worse than gas!

 

you should be able to get a new 1 at most any chevy dealer.
seems like the last 1 i got was around 6 or 7 dollars or so. make sure you have a cap with a good seal to put on it too.
don't use 1 for a tire, it won't last.

 

I agree ... GM, and don't use a tire one.
