Fuel pressure regulator

[MrobsMan]

Does anyone know where you can buy a factory fuel pressure regulator spring cover for the tbi engines? I don’t need the regulator housing just the spring cover..

I've wrecked a few trying to make them "adjustable".

If GM isn't selling them (discontinued, I bet) then about the best you can do other than scour the Treasure Yards, is to buy the entire regulator/injector top piece.

I got one off of eBay, two years ago, at a price I can't match today. Just looked on eBay, prices start at ~$70 and go to more than double that. I paid $19.
