Important:
• | Before attempting the Fuel Tank Leak Check place a dry chemical
(Class B) fire extinguisher near the work area. |
• | Before removing the fuel tank for a suspected leak, make sure
the fuel pipes are not leaking onto the fuel tank. Once removed, make sure
fuel is not leaking around the fuel sender gasket. |
• | This check requires a fuel sender assembly and a fuel sender gasket
to be installed in the fuel tank. |
- Disconnect the negative battery cable.
- Relieve the fuel system pressure. Refer to the Fuel Pressure Relief
Procedure.
- Drain the fuel tank. Refer to Draining Fuel Tank.
- Remove the fuel tank. Refer to Fuel Tank and Fuel Filler Pipe
Replacement.
- Cap the fuel feed pipe, the fuel return pipe, and the EVAP pipe
on the fuel sender assembly.
- Connect a piece of hose to the filler pipe nipple and plug the
opposite end.
- Submerge the fuel tank in water or apply a soap solution to the
outside of the fuel tank.
- Apply 35 kPa (5 psi) air pressure to the vent hose
on the fuel tank. Air bubbles appearing from the fuel tank indicate a leak.
