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
1. Note the position of the fuel pickup filter in relation to
the bracket before removing the filter. Remove the filter
by pulling on it while rotating it in one direction.
Discard the filter.
2. Note the polarity of the electrical connections at the
pump and remove the electrical connections. Write
down which wires are connected to the positive and
negative terminals and the respective color of each
wire's insulation.
3. (Note: Your original pump will be mounted in one of
two ways. See Fig. 2 and 3 . If it is mounted as shown
in Fig. 2, then follow step 3a for removal. If it is
mounted as shown in Fig. 3, follow step 3b for removal).

3a. Remove the hose clamps, if so equipped, cut the
rubber hose, and remove the pump from the
bracket.
Remove the cut hose piece from the
bracket tube and discard it, along with the used
hose clamps.
3b. Remove the pump by inverting the bracket. Pull
down on the fuel pump until the inlet end clears the
pump support and swing it to the side. Remove the
pump and pulsator from the bracket fuel outlet tube.
Save the pulsator and the pulsator to fuel pump
rubber spacer for use in mounting the new fuel
pump.

4. Inspect the bracket to ensure that the pump support has
not been bent during pump removal. The flat surface of
the support should be perpendicular (square) to the tube
it is welded to (See Fig. 4). If it is out of square, carefully
bend it back to square to allow the pump to fit properly.
Take care not to damage the support or the tube.
5. Install the supplied pump rubber adapter grommet onto
the inlet side of the pump. Test fit the pump on the
bracket and rotate the adapter grommet on the pump as
required to obtain the best pump outlet fitting to bracket
outlet tube alignment.
6. (Note: Your original pump will be mounted in one of two
ways. See Fig. 2 and 3. If it is mounted as shown in
Fig. 2, then follow step 6a for installation. If it is mounted
as shown in Fig. 3, follow step 6b for installation.)

the pump. Invert the sending unit and place the
remaining clamp over the fuel outlet tube. Install the

rubber hose and pump onto the fuel outlet tube on the
bracket. Guide the pump adapter grommet into the
pump support on the bracket. When the pump and
adapter grommet assembly are firmly seated in the
pump support, verify that the rubber hose is seated
against the fuel pump, and then position and tighten
the hose clamps.
6b. Using petroleum jelly, sparingly lubricate the fuel pump
outlet tube on the bracket and the pump outlet fitting.
Install the rubber spacer and pulsator onto the fuel
pump. The spacer and pulsator are to be fully seated
against the pump when properly installed. Invert the
bracket assembly and install the pump and pulsator
assembly onto the fuel outlet tube on the bracket.
