I'm Awesome
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.
