I have a 1993 SSEI Bonneville - and I want to change the fuel regulator, It looks like its welded to the the fuel rails. would I need to replace the whole fuel rail or can I just replace the fuel regulator by itself.

If you look closer you will see it'* held in by a ring. That ring has two little holes in it. Those are used for ring pilers and it comes out easy.

Is there anyway anyone can post a removal and installation pic of this- I am really baffled by it because it looks like its welded to the fuel rail - I guess I havent really looked at it very very closely.

Look at it closer. The FPR is held in with a retaining ring. Look at it from the passenger side.

Use retaining ring pliers to remove the ring, then muscle it out. They can be VERY difficult to pull out.

Different year, but same basic design. Check the 3rd picture down.

Wow Awesome thank you - those are wonderful pictures and now I fully understand what everyone just said. Thank you - this will also help all the others that have the same problem I had in locating and removal and installation of the fuel regulators in our 1993 SSEI - Thank you so much.
