Is your fuel dash gauge acting up? When it starts to register intermittently, fluctuate with its readings or just plain stops working, you can usually trace it back to the fuel tank sending unit.
These units are always sitting in fuel. They are constantly moving and they are subjected to vibrations. That’s why they are most often the cause for faulty readings on the dash gauge. The good news is that replacing a Corvette fuel tank sending unit is a relatively easy job that can be performed by anyone with a few good hand tools.
Follow along with Zip’s technical article “1963-1974 Fuel Tank Sending Unit Replacement” as we walk step-by-step through the replacement process on our Project 64. We’ve even included photos with each step.
Before you start, there are some things you should keep in mind. Run as much fuel as you can out of the gas tank. It’s much easier to drain 4 or 5 gallons of gas than 20. Always work in a well ventilated area and wear eye protection. You’ll also want to gather a fuel drain pan, rubber fuel hose and clamps, emery cloth or sandpaper, hydraulic jack, jack stands and a shop manual for your car along with the basic hand tools.
With those few tips in mind, you’re ready to get started.
