I just changed the fuel sending unit and pump assembly on my 91 Mazda Navajo. The problem was the gauge was always reading empty. Jeff Singleton et al instructions in the Ford Explorer Maintenance Section are accurate and helpful. My problem was also a leaky float, but rather than repair/replace I replaced the entire unit - $123 at O'Reilly.
I had trouble, however, removing the fuel lines. Using the plastic tool in the loaner removal kit, the lines refused to separate regardless of the twisting, tugging and cussing. Resisting the urge to take a hacksaw and a pair of pliers to the connector, the solution was to crawl up under the car, peer over the tank with a falshlight and use a jeweler's screwdriver to pry the spring out. The replacement springs for the large fitting (13mm) is Dorman part # 800-008 available at O'Reilly's. The smaller size is available there also. Even though I had the spring out the connection still wouldn't separate until I twisted and tugged some more. Inspection of the disassembled fitting showed no damage or corrosion so I snapped them all together and away I go. The next task is a R-12 to R-134A upgrade.
