INSPECTING
AT THIS POINT

If the pump has failed earlier test and must be replaced,
proceed to INSTALLING.
1. Inspect the fuel screen and blow clean with low pres-
sure compressed air.
2. Move the float lever and check for free movement.
The float assembly should return to the lower posi-
tion without force. If not, replace the fuel pump
assembly.
3. Test the fuel level sensor by connecting a multimeter
(A) to the fuel level sensor leads (B); then select
OHMS. The multimeter should show 86 ohms at full
fuel position (C) and 5 ohms at empty fuel position
(D).
 NOTE: If readings are erratic, clean the resistor
wiper and resistor with clean alcohol and retest. If
still not correct, replace the fuel level sensor.
4. To replace the fuel level sensor, use the following
procedure.
A. Disconnect the two-wire connector (A); then
press the fuel level sensor toward the top of the
fuel pump to release it from the mounting slot (B).
B. Engage the tabs (C) of the fuel level sensor into
the mounting slot (B) and press toward the bottom
of the fuel pump to latch in place; then connect
the two-wire connector (A).
INSTALLING
1. Mark the new fuel pump with a reference mark in the
same location as the removed pump; then place the
new gasket on the pump.
2. Remove the material covering the fuel pump open-
ing; then carefully guide the fuel pump into position
taking care not to damage the float or float lever.
3. Rotate the fuel pump until the match marks align;
then install the mounting screws and tighten securely
using a crisscross pattern.
 NOTE: It is important to install the fuel pump with
ATV2116
the correct orientation to ensure adequate float lever
clearance.
4. Connect the wires and fuel hose; then connect the
negative battery cable and turn the ignition switch to
the ON position. Note that the fuel pump runs
momentarily and the fuel gauge indicates the proper
fuel level.
5. With the transmission in neutral and brake lever lock
engaged, start the engine and check for normal oper-
ation. Check for any fuel leaks.
6. Install the gas tank cover, side heat shields, and seat
making sure the seat locks securely.
