Incorrect Fuel Gage Reading (Install New Fuel Tank Strap Spacers and Bolt)

Some customers may comment that after fueling their vehicle, the fuel gauge reading may be incorrect and that it appears to be stuck, indicating approximately 1/4 tank of fuel.

Inadequate clearance between the fuel level sender float arm and a baffle internal to the fuel tank may result in an actual contact condition between the arm and baffle. This contact may then result in an inaccurate input to the fuel gauge and an erroneous reading being indicated.

1. Raise and suitably support the vehicle.
2. Remove and discard the left front fuel tank strap attaching bolt.
