Fuel Leakage Inspection

WARNING: Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death and damage. Always carry out the following procedure with the engine stopped.

1. Disconnect the negative battery cable.




2. Remove the fuel pump relay.

CAUTION: Connecting the wrong fuel pump relay socket terminals may possibly cause a malfunction. Carefully connect the specified terminals only.




3. Connect fuel pump relay socket terminals 30 and 87 by using a jumper wire.

WARNING: Before connecting the negative battery cable be sure all fuel connections, clamps and fittings are secure. Fuel pump will operate at full pressure anytime the cable is connected to the battery. When the cable makes contact, it is sure to arc and create a danger of ignition or explosion.

4. Connect the negative battery cable to operate the fuel pump.
5. Pressurize the system this way for at least 5 minutes to be sure of no leaks.
6. Disconnect the negative battery cable and remove the jumper wire.
7. If there is fuel leakage, inspect for damaged fuel hoses, hose clamps and fuel pipe sealing surface and replace as necessary.
8. After repair, assemble the system and repeat steps 1 to 6.
