CAUTION: Use suitable covers to protect carpet, upholstery, etc. NOTE: The Fuel Sending Unit that you remove from the vehicle may look different from the new replacement service part (see Figure 43). 1. If the fuel tank is more than ¾ full, use a suitable device to remove fuel from the fuel tank until the fuel level is ¾ full or less. 2. Release the fuel pressure from the fuel system using CONSULT-II (or other suitable method). Follow the procedure in the “EC” section of the Service Manual. 3. Remove the Fuel Sending Unit as follows: a. First, use shop air to clean the area around the Fuel Sending Unit and Mounting Flange (see Figure 35). b. Then, apply Rust Penetrant (999MP-A3020P) to the Fuel Sending Unit Mounting Flange Bolts (see Figure 36). Allow the penetrant to “soak” for a few minutes.
