Would anyone have the correct part number for the oil pressure switch for the fuel pump.
Thought is was 87-864252 .That is the wrong unit, but if someone needs that one I have it.

87-864252A01 Try that one. The one you got was for a 5.7 serial #0M331444 & Up

That might do it, Somebodys always changing something .What ever happened to keeping it simple.The old one came with blade terminals, the new one now needs a harness.Another point for a failure.
Thanks for looking.

For anyone else following this post on the fuel pump pressure switch ,if you have the one with 2 blade terminals it is NLA.This kit updates to the new style and includes a wiring harness to plug into your existing wiring connectors.
