I want to replace the sending unit. Gauge is erratic, I know this to be normal but ever since the original failed the readings have been lower than they used to be, and I feel they are higher than displayed. I'm looking to get an ACDelco unit, only place I can find it is GMPartsDirect, and the listing is as such found in the mechanical catalog:

Mechanical Catalog - 1995 - Pontiac - Bonneville
, Oil pressure sending unit, all models

I'm guessing all of ours are the same? If not can someone tell me where to acquire an ACDelco unit from?

Did you try RockAuto?

If you go to ACCDelco.com, you can get a list of all the vehicles that have the same part number sender.

They are not the same. Cars with a gauge use a different sender than cars with a dummy light only.

Can I possibly get a part # or place to get an ACDelco unit?

25627057 is the only number I can find. GMPD and Monsterparts say they have it.

So, is that the correct one? When I had last looked it up, there was no part # and it was very basic as I posted above. Not in any way saying you are wrong, just trying to clarify if your statement is one of saying "this is the part number" or "this is all I could find from my looking"?

I found it two places, and both said "all models". I'm starting to think that if there was two, they figured out that the "guage" version would work for the "just a light" version.
