FUEL PUMP
Removal & Installation
The fuel pump is attached to the fuel sender assembly inside the fuel tank. See FUEL SENDER ASSEMBLY for removal and installation

FUEL SENDER ASSEMBLY
Removal
Release fuel system pressure. See FUEL SYSTEM PRESSURE RELEASE. Remove the fuel tank. See FUEL TANK. Remove the fuel sender shield nuts. Remove the fuel sender shield. Disconnect the fuel sender electrical connectors.
CAUTION: Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

Disconnect the fuel pipes from the fuel sender. See FUEL LINE DISCONNECT FITTINGS. Using Fuel Sender Lock Ring Tool ( J-39765-A 1), remove the fuel sender lock ring. The fuel sender assembly will spring up when the fuel sender assembly lock ring is removed.
The fuel sender must be tipped in order to remove the sender from the fuel tank. Remove the fuel sender from the fuel tank. Remove and discard the fuel sender seal.
Installation
Clean the fuel sender sealing flange. Install the NEW fuel sender seal to the fuel tank. Do not fold over or twist the fuel pump strainer when installing the fuel sender assembly, as this will restrict fuel flow. Also, assure that the fuel pump strainer does not block full travel of float arm.
Install the fuel sender and the fuel sender lock ring. Use the Fuel Sender Lock Ring Tool ( J-39765-A1) in order to install the fuel sender lock ring. Install the fuel pipes to the fuel sender. Install the fuel sender sensor electrical connectors. Install the fuel sender shield.
Install the fuel sender shield nuts. Tighten the nuts to specification. See TORQUE SPECIFICATIONS. Install the fuel tank.
