Re: 2004 Vortec 5.3 Oil Pressure Sending Unit?

I've been right on top of the driver's side of the engine. Just cannot get my hand thru the mess of lines, much less hold a ratchet. Everything's pretty solid on all those cables and such. If I knew what would happen if I disconnected the fuel line, that would be cool. But, I don't want to get a fuel feed problem started. You know, introducing air into the line. I know very little about fuel injection systems, owned all carbed cast iron engines up till now except for 2 C5 Corvettes (99 and 01). Never had to mess with them at all.
