2009 Ford Mustang Fuel Pump Parts Q&A

• Q: What safety precautions should be observed when servicing the fuel level sensor and fuel pump module on 2009 Ford Mustang?

  A: The need for safety measures during maintenance of the fuel level sensor and fuel pump module stems from the flammable characteristics of the mixtures inside them. First disconnect the battery ground cable while lowering the fuel system pressure. The fuel tank filler cap should be turned counterclockwise with caution to free its threads before you put it to the side. Slightly agitate the Fuel Draining Hose before removal yet avoid breaking the fitting connection while ensuring the hose reaches into the fuel tank filler pipe until the fitting activates the safety valve. A Fuel Storage Tanker should be connected to the hose which will drain enough fuel to drop the level below the position where the fuel pump module is attached. Rear seat cushions need removal along with the fuel pump module access cover. The user needs to clean the fuel pump module connections while removing the electrical connector. The work area requires absorbent pads underneath to capture any fuel leakages before removing the rear fuel tube-to-fuel pump module quick connect coupling. The Fuel Tank Sender Unit Socket enables lock ring removal from the fuel pump module without harming the float arm so discard the ring properly. Remove the fuel pump module from the tank while disconnecting its internal fuel tube-to-fuel module coupling. Drain everything stored in the module into a proper container. The O-ring seal contact surfaces at the fuel pump module flange and fuel tank must be checked for bending, scratching or corrosion damage because the fuel pump module or fuel tank will need replacement in this case. Place new clean engine oil on the O-ring seal then apply it to its fitting position while using fresh fuel pump module lock ring hardware. Position both arrows properly before securing the lock ring by tightening it until it stops at the fuel tank stop tabs.
