    Hey guys, I have searched and cant find what I am looking for.

    I am rebuilding the TBI on my 4.3 TBI and the fuel pressure regulater spring disenegrated when I took the TBI apart. The spring does not come in the rebuild kit, and I need to know a part number or something to get a replacement from a parts store.

    Thanks!!

    if you want to do some searching, on thirdgen.org they have part numbers for different spring rates for the regulator. they were in threads about the vaccum adjustable fuel pressure regulator. hope this helps.

    did you check at a gm parts dealer?

    I dont know if anyone is going to have the spring. You will probably have to buy the whole regulator. Sorry. I bought an adjustable regulator from cfm tech and it didnt come with a spring. It re-uses the old spring. I would say buy a stock pressure regulator from an auto parts store, take the spring out of it, and return it as defective. When they figure out it had no spring, they will figure thats why it was defective.

    spring

    Go to your local pic n pull or junk yard and find a 4.3 TBI and pull the spring out of it. (pocket part)

    Took awhile, but I was finally able to look at the '87-88 parts manual for the TBI.

    It shows the regulator, but only mentions a kit, and says nothing about the kit containing a spring.

    I know, nothing new here, but looks like the GM parts guys weren't wrong for once. :(
