A.I.R. Pump Valve (Discontinued)

[CTX-SLPR]

Howdy,

So I've been getting a really obnoxious squeeling/humming/gurgling sound from underhood on my 98 Vortec 454. Snooping around for it, it's coming from the mushroom shaped A.I.R. Pump Valve (12550930 part number on top). Looking for a replacement it shows discontinued everywhere. It doesn't seem like it's the fuel pressure regulator though I might just do that seeing as I have the parts already.

Any idea of what could be used instead? Living in CA, they go snooping for things like that at the annual smog check.

If all else fails, either visit the Treasure Yard for a functional used unit, or take the faulty one you have off the vehicle and figure out a way to fix it.

There's plenty of parts that were not INTENDED to be disassembled,,,that can be disassembled, cleaned, and returned to functionality. I'm not saying it's easy, and I'm not saying you're guaranteed to have a working part when you're done. I'm saying that if you're clever and resourceful, you have a better-than-50/50-chance of success.

Didn't even think to look on a 97, interesting that it is still available and not that pricey either.

Thanks to everyone
