Default Fuel Pump Regulator

1997 Bonneville 3800 series 2.
How does the fuel pump regulator come off of the fuel rail?
Are most GM ignition coils the same, as in buick, chev, olds 3800 series 2?
Replacing TPS that does not have slotted holes for adjustment, so does it just go straight on?
Thanks

You need to use snap ring pliers after you've depressurized the fuel lines. I hear it just lifts out after that, but I haven't done this myself.

Yes. You'll find testing and replacement instructions elsewhere in the forum.

As long as you turn it in the correct direction when installing, it'* entirely self-adjusting. At least I've never had to adjust mine.

Colin pretty much aced that one.

FPR the pliers make it easy. Then pull and wiggle it out.
Coils are different between NA and SC cars. You'll want SC coils. IIRC the color underneath is yellow on the SC'd.
TPS has no adjustment after 95 and it'* a straight bolt on.

If you are picking up coils though...why not get the better ones?

So the coils are interchangeable from N/A to Super charged?
