Re: Schrader valve
I did that yesterday. Just pulled a couple from CPI setups with a core removal tool; the guy gave them to me. FWIW, I called the local GM dealership looking to see if they had one new (didn't know if there was any rubber on the core that might be dried up / cracked from sitting in the boneyard), and they didn't even list / show one on their diagrams, or have a PN listed. I found one in a rail that still had fuel in it, but it didn't look like there was any rubber; it dropped right into my rail and works fine.
