Caution: Place a dry chemical (Class B) fire extinguisher near the area before performing a Fuel Tank Leak Check. Before removing the fuel tank for a suspected leak, make sure that the fuel pipes or the tubes are not leaking onto the tank. Once removed, make sure that the fuel is not leaking around the fuel sender O-ring. Failure to follow these precautions may result in personal injury.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
2. Remove the fuel tank. Refer to Fuel Tank Replacement .
3. Plug all of the outlets as follows:

•	Install the filler neck and the vent hoses, the upper neck assembly, and the filler cap.

•	Install the fuel tank sender with the seal and plug the fuel lines.

•	Install a short piece of fuel line on the fuel tank meter vent tube.

4. Apply approximately 7 to 10 kPa (1 to 1.5 psi) air pressure to the tank through the vent tube. Pinch the fuel filler hose in order to retain the air pressure.
5. Test the suspect area for leaks with a soap solution or by submersion. If a leak is noted, replace the tank. Refer to Fuel Tank Replacement .
