TECHNICAL INSTRUCTIONS

FUEL SYSTEM PRESSURE RELIEF

WARNING:
FUEL SUPPLY LINES WILL REMAIN PRESSURIZED FOR LONG PERIODS OF TIME AFTER ENGINE SHUT DOWN. THIS PRESSURE MUST BE RELIEVED BEFORE SERVICING OF THE FUEL SYSTEM IS BEGUN. A VALVE IS PROVIDED ON THE FUEL CHARGING ASSEMBLY FOR THIS PURPOSE. REMOVE THE AIR CLEANER. ATTACH EFI AND CFI FUEL PRESSURE GAUGE T80L-9974-B OR EQUIVALENT TO THE FUEL DIAGNOSTIC VALVE ON THE FUEL CHARGING ASSEMBLY. PRESSURE IN THE FUEL SYSTEM MAY NOW BE RELEASED.

FUEL TANK DRAINING PROCEDURES





The FF Taurus fuel tank cannot be drained through the fuel tank filler pipe. A special screen is installed in the fuel tank filler pipe to prevent siphoning of fuel through the fuel tank filler pipe. The FF Taurus fuel tank is equipped with a drain tube connected to the fuel tank sending unit and pump located on the right hand side of the vehicle. The drain tube has a quick disconnect for this purpose (Figure 1). It is not necessary to lower the fuel tank to drain the system.

CAUTION:
Do not drain or store methanol fuel into any unleaded gasoline tanker other than Rotunda Fuel Storage Tanker and Adapter Hose 034-00020 or equivalent. Damage to the fuel tanker pump and control valve seals may occur.

Drain the system as follows:

1. Depressurize fuel system as outlined above.

2. Remove foam cover and protective rubber cover from drain tube.

3. Connect drain tube (Fig. 1) quick disconnect fitting to Rotunda Fuel Storage Tanker and Adapter Hose 034-00020 or equivalent. Drain fuel from fuel tank.
