Does anyone know the part number for a tpi fuel pressure regulator diaphram? I have a BBK adjustable reg to install in place of the leaking factory unit but I still need a new diaphram. If anyone knows the part # or where the get it I'd appreciate it, I havn't had much luck locally. Thanks!

thanks thats just what i'm lookin for, shame they don't list the pn, is that an average price?

 

From what I can tell. Mid America Motorworks (who I use for some Corvette parts) sells it similarly for about 80.

 

wow, that is NOT an average price. I was looking for one too, lucky for you I bookmarked the links...atleast 1 of these should be near you and any store should be able to order it for you if they don't have them in stock...

Thanks for the replies, looks like I'll try autozone.

 

I'm gonna go to the junkyard and pull one off a car because I'm not certain if thats the culprit of my issues. Those diaphragms are a 80's GM staple. They are the same piece in almost every GM car, you just have to fine the FPR... I think I'll pull one of a v6 thirdgen and pay like $1. If thats the issue, then I guess I'm buying a new one...

 

yeah I have several spares around, all in tpi fuel rails, they just tend to be in horrible shape due to age, if they don't tare comin out you're lucky. The one im replacing was very brittle but still in one piece. It doesn't look too bad to the naked eye but when I was taking it apart I noticed liquid fuel in the vaccum line, a sure sign of failure. It didn't show any symptoms though, so I'm assuming it must have been a small leak. It's one of the final things I need to finish up my engine swap so it will defently be replaced with a new 1. I just don't want to spend a fortune on it

 

I bought mine from advance auto parts or auto zone a couple of years ago
