BRACKET REMOVAL
1. Thoroughly clean all dirt and debris from the top of the
tank. Clean out any dirt from around the locking ring
and retainer. This must be done to prevent dirt of
foreign material from falling into the fuel tank while
removing the bracket.
2. Lubricate the locking ring with penetrating oil to assist
in its removal. Remove the locking ring by rotating in a
counterclockwise direction. This can best be
accomplished safely by using the proper service tool as
specified in the
factory service manual. Using the
proper tool is ideal. However, the locking ring can be
removed by other methods. Whichever method you
use, do not use any method that could potentially cause
sparks resulting in fire or explosion.
3. Once the locking ring is removed, carefully remove the
bracket from the fuel tank. Be careful not to bend the
float arm or scratch the float when it is removed.
Discard the old fuel tank to bracket o-ring seal.
PUMP REMOVAL AND REPLACEMENT
(Note: See Fig. 2 for reference during all steps.)
1. Note the position of the fuel pickup filter in relation to the
bracket before removing the filter. Remove and discard
the filter.
2. Prior to removing the lead wires, inspect the terminal
ends attached to the fuel pump. Some vehicles use a
locking terminal on which a tab must be depressed to
release the terminal. Remove the wires from the fuel
pump without damaging the terminal ends, as they are to
be reused. Note which wire is positive (+), and which
wire is negative (-).
3. Remove the four screws that hold the upper and lower
bracket sections together. Remove the lower section and
fuel pump isolator and set them aside.
4. Note the fuel pump’s orientation. Remove the hose
clamps and remove the fuel pump and fuel hose from the
pump bracket.
5. Install the new fuel hose onto the new fuel pump outlet
fitting and place the hose clamps over the fuel hose.
Install the fuel hose onto the pump bracket. With the fuel
pump properly positioned, tighten the hose clamps.
6. Install the fuel pump isolator over the end of the fuel
pump inlet. Place the lower section of the pump bracket
over the pump inlet and install the screws. Make sure
that the fuel pump is properly positioned in the
assembled bracket. If not, reposition the fuel pump as
necessary.
7. Install the lead wires onto the pump terminals, making
sure that proper polarity is maintained.
8. While maintaining proper orientation, push the new filter
onto the pump inlet until it is fully seated.
9. Thoroughly inspect the pump and bracket for any
possible defects before installation into the tank.
BRACKET INSTALLATION
1. Inspect the fuel tank for dirt and debris. If the amount of
dirt or debris is excessive, clean the fuel tank before
installing the bracket assembly.
2. Inspect the bracket to make sure it is clean and ready for
installation.
3. Place the supplied fuel tank o-ring seal in the groove at
the fuel tank opening. Place the bracket assembly into
the tank using care not to disturb the o-ring seal. Also
use care not to fold or twist the filter, as this could cause
restricted fuel flow. Install the locking ring and rotate it
clockwise until it is properly seated against the stops.
Check service manual for an approved sealant for locking
ring.
