Several years ago I bought a used OEM Vacuum Pump ,I bought it from a fellow
out West ,that repairs them .
I didn't install it immediately .several months later I installed it and it
didn't work to good.
Upon inspection ,he had gobbed some Silicon seal on the ruptured Diaphragm
without cleaning the burnt carbon off it.
I ended up buying a new one ,which I should have done in the first place.
Beware of buying unknown repaired Devices ,where Safety is concerned.

I haven't really thought through the pump vs reservoir implications. I
just installed a Cad suspension compressor as the vacuum pump, considering
it more reliable than the old Delco pumps at this stage of their life (I've
got a bunch of them with ruptured diaphragms).

Yeah, I've given up on those pumps. But I do have two of them in service:
One on my S-10 and the other on the CRV, both for the $30 toad brake.
They've been on there for at least 8, maybe 10 years, and work find. But
that's very light intermittent duty, and they're not exposed to engine
vacuum (and backfires).

Is this the pump you all are talking about? I pulled this one from a Seville as I thought they were the same as the later GMC suspension pumps and someone might need it.
