    Check the truck side of the fuel pump harness. I can't remember if it's a three or four wire setup, but on the trucks of that vintage the ground wire on the truck side was a short wire that screwed to the top side of the frame rail, close to where the filler tube passes over the frame. The wire would corrode there and cause a high resistance condition in the ground circuit.

    Airtex lasted about a year in mine. Had no choice, it was all I could get on a Sunday. Carters have sucked. I just put a Delco in.

    One new delco pump in today. All is now well. Hopefully it remains that way. Not fun 30* and windy, but I needed to get it done.

    Waiting for spectra to call me back on the warranty.

    to make Dave cry. Mike has seen much worse.

    just an example

    Leaking fuel lines!

    Sender lines kinda beat, but not as bad as i expected. Pump had been replaced at some point, and I think the fuel lines were too.

    the aftermath

    both WCs looked like this, neither were leaking. the line broke upstream more. Feed lines to front hoses looked equally old & thin

    Mike, this is why I think the fuel lines were previously changed or at least monkeyed with. This is where the two return lines met. Should be a union. WTF is this? Tht is no GM o-ring line connector. lol I could not get it apart.

    Looks stock to me, Scott. Pull it apart and you'll find a flared connection inside that. GM also used those on brake lines in the LeSabre/Park Avenue platforms for the brake lines.
