The cheapest option for rebuilding the fuel pump in the XJ was to pick one up from the junkyard. I show a lot of detail in this video since the repair process is intricate. Don’t forget to buy a new pump to tank o-ring seal like I did !!!! The sending unit for both fuel pump modules matched the fuel gauge perfectly.
The sealing surface for the body to front face plate o-ring, has 2 major scratches across it. This was done by a real rookie. Those scratches are where the freon sniffer found a major leak. The square cut o-ring cant’t seal across the Grand Canyon!! Now I need to find a used compressor from the junkyard.
