Fuel Tank: Service Precautions

NOTE: To prevent possible accident when working on fuel system, disconnect the vehicle battery negative (-) cable(s) and provide the appropriate fire fighting and safety equipment in accordance with local fire and safety regulations.

Before removing the fuel tank to correct a leak, a careful inspection of the tank should be made to determine the actual source of the leak. "Seam leaks" often turn out to be leaks at the filler neck, fuel line connections, or at the tank sending unit seal. In such cases, fuel runs down the side of the tank to the flanges and drips off at points along the seam giving a false indication of leaking seams. If careful inspection reveals that the tank is actually leaking, remove the tank for repairs as required.

A leaking fuel tank must be repaired or replaced immediately. In addition to increased operating expense, leaking fuel tanks represent a serious fire hazard. No leakage is allowed anywhere in the fuel system lines or tank.
