REMOVAL:

Properly relieve the fuel system pressure.
If not done already, disconnect the negative battery cable.
Raise and safely support the vehicle with jackstands.
Safely drain, then remove the fuel tank assembly.
Remove the fuel tank sending unit and pump assembly by turning the fuel pump cam lock ring counterclockwise, then lift the assembly out of the tank.
Remove the fuel pump from the level sensor unit as follows:
A. Pull the pump up into the attaching hose or pulsator while pulling outward away from the bottom support.
B. Take care to prevent damage to the rubber insulator and strainer during removal.
C. When the pump assembly is clear of the bottom support, pull the pump out of the rubber connector for removal.

INSTALLATION:

Replace any attaching hoses or rubber sound insulator that show signs of deterioration.
Push the fuel pump into the attaching hoses and install the pump/sensor assembly into the tank. Always use a new O-ring seal.
Be careful not to fold over or twist the strainer when installing the sensor unit. Also, make sure the strainer does not block full travel of the float arm.
Position the cam lock and turn clockwise to lock.
Install the fuel tank.
Fill the tank with gas and check for fuel leaks.
Connect the negative battery cable.
