Does anyone have a part number for the fuel pump connector/pigtail for the pass side fuel pump? Mine still works but the wiring is brittle and some shielding missing caused by the excessive draw of the old pumps

Part number 211 540 07 00 wiring harness

You can always cut off the bad portion of your harness, cut the new assembly referenced above, then resolder (stagger the splices, of course) using copper sleeves and heat shrink tubing (personally, I'd use two layers of heat shrink followed by electrical tape).

Be sure to get the small foam piece as well. It goes on the underside of the metal cover so as to provide cushioning and insulation to the new wires and connector. My old connector insulation was brittle and rubbing against the bare metal lid. That could have been very ugly.

On the fuel sender side, there is an adapter that may be necessary when upgrading to one of the new units. MB part number is 2114400507.
