Trying to replace the fue pressure regulator on my 91 Deville.....The mounting screw comes from the bottom of the block and I can't see what type or size screw it is....Anybody know what type or size so I don't have to take the entire fuel rail up to turn it over?

Thanks for any help you can provide....

Jim

Found the below on another thread while I was waiting........Now I have to go get one that will fit in the space :thumbsup:.....they said they had to take the rail up...hope I ca avoid it.

Its a Torx T-27 bolt.

There is very limited room under the FPR, I wasn't able to get it any other way.

yup, T-27.

The rail has to come off.....

Yeah, you meant it when you said "screw" lol... Off with the rail. Funny how simple it would have been for that to come from the top...*kicks GM in the pills*

Was able to get the regulator changed without lifting the fuel rail :dance:. Thanks to you guys previous posts was able to take a T-27 torx bit and tape it to a 1/4 wrench and get in to remove the screw.....

Had to remove the distributor cap and the rotor cap inside, but that gave me enough room to remove the bolt.

I appreciate your Help!!!!!
