Yeah, I can't help you with either of those since I don't work with aftermarket parts. Your best bet would be to get a GM fuel pump. If it requires a new connector, at least the wire colors are usually the same and the terminal letters will definitely match up. It comes with good directions as well if any of the wire colors are different.

I'd only do this after making sure that you are getting power to the fuel pump.

I am only getting four volts to the pump, so now I am looking toward a broken positive wire running to the body block. I was under the impression that Delphi was the OEM part, is it not?

Yeah, I'd start looking at a wiring issue if you're only getting 4 volts. And Delphi makes parts for multiple brands, but if you bought it at O'Reillys it's NOT factory.

I found a website that says I should be able to take the fuel line off and blow through it, pushing and and hearing bubbles in the tank. As I am sure you know, the person who posted this could be correct or could be a raging lunatic. Csan you tell me if this is true?

Blowing through the fuel line isn't going to help your low voltage problem any way you look at it, so it doesn't matter if that person is correct or not. It won't make a bit of difference either way.
