fiatslug87 Posted May 24 Share Posted May 24 CRUISER'S MOSTLY RENIX TIPS IMPROVING THE FUEL PUMP GROUND The fuel pump and fuel tank sending unit ground at a sheet metal screw up behind the spare tire on an XJ, and behind the driver’s taillamp on an MJ. Not only is a sheet metal screw a lousy way to ground things, this ground path is long and travels through some connectors that are prone to corrosion and moisture. Locate the black wire on the HARNESS side of the fuel pump/sender 3 wire connector. Remove a 6″ length of the split loom covering. Strip back about 1/2″ of insulation from the BLACK wire. Take your new ground wire, preferably at least 14 gauge and 12 to 18 inches long as needed, strip it about 3/4″, and wrap it around the exposed part of the harness plug wire. Solder the connection. Tape it up and reinstall the split loom covering. At the other end of your new ground wire, add a crimp on eyelet. Attach the eyelet under a bolt that goes directly into the chassis. Be sure to clean the attaching point til shiny and apply OxGard to the contact surfaces. Revised 10-16-2018 Link to comment Share on other sites More sharing options...
Eagle_SX4 Posted July 27 Share Posted July 27 Just did this on my truck and just had one improvement to add. Instead of taping the wires after soldering them. I used a weather pack dissembly tool and pulled the wire out of the connector and then used some 3/16 inch marine heat shrink.(Has hot glue on the inside for a weather tight seal). It was a tight fit over the weather pack seal but it did fit. Link to comment Share on other sites More sharing options...
