My Pete rebuild

[Nostalgic]

Ok, after spending way too much time on the subject, I finally have an answer to the my madness.



The new one in the picture is the one hanging on the E-6 Valve that supplies air for the seats. It's 3/8"Inlet, 1/4" outlets with a red cap that opens at 85 +/- psi, and closes at 67 +/- psi.
Part# 223-685

The painted black one, which was hanging off my secondary air tank, supplies the transmission. It's 1/2" inlet, 1/4" outlets, with a red cap that specs say opens at ≤100 and closes at ≥70. Part# 223-585 According to Bendix tech, for my model # AD-IS, 801266, the acc. ports both open AND close @ approx 109 psi, even though that doesn't sound entirely accurate...

All of this just so I know WHY I should spend $60 on a valve that didn't have a clear explanation as to why it was there.
