Fuel Pump Problems
You can't miss the fuel pump
on the Super X. When you click the ignition switch to the "on"
position, you hear a distinct whirring sound. You can hear this sound up
to about 10 feet away from the bike! So what do you do if you don't hear
that sound?
1) Replace the fuel pump.
Unfortunately, this requires removing the tank from the bike.
First, remove the instrument cluster.
Next, mark the three wiring harness disconnects BEFORE disconnecting
them, so you will know which connector goes where when reconnecting
them. Then place a rag at the front of the gas tank BEFORE
removing it and disconnect the fuel line. The fuel line should have very
little fuel in it as the electric fuel pump also acts as automatic
petcock and shuts the fuel off automatically when receiving no
power.
Carefully take the fuel tank off and lay it upside-down on a moving
blanket or other non-scratch surface. There is a large snap ring
retaining the fuel pump, and once removed the resistance of the large
O-ring initially holds the fuel pump unit firmly in place; a Morgan
Knocker (slide hammer) affixed to the fuel pump eases removal. Once out
replace with a Carquest #E2002 fuel pump.
2) While the gas tank is
off, follow all the wiring harness leads and make sure that they are
properly routed against abrasion from the gas tank and other parts of
the motorcycle; check the wiring loom runs over the rear cylinder to see
that they are away from the head. Check the your positive
battery cable lead for routing. Also heed the spark plug suggestions
and make sure that they are at 15 ft. lbs. of torque
(you may consider using anti seize compound on them). If you want to
install the DRIVING LAMPS, now is the best time to do so.
3) Reinstall the tank.
Just go in the reverse order from removing the tank and you should be
back in business.

Or, if you don't want to
replace the fuel pump, try this:
1) Remove the end of the
pump where the impeller is (I had to do this with a bit of
educational guessing). Keep aware of what wires feed to what in the
pump. Once the gears to the pump shaft are exposed, you can take a very
small flat blade screwdriver (I used a jeweler's screwdriver) and move
the exposed gear back and forth with gentle pressure so as not to score
or break a gear tooth. It won't take much to get the gear to break free
of the varnish and begin to move. Reassemble the pump and reattach the
power leads. Turn the bike on and you will hear the pump prime
immediately. Reassemble everything. Be careful when you reinstall the
large retaining clip in the tank (it's a scratch in the paint waiting to
happen).
