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
pressure 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 multime-
ter (A) to the fuel level sensor leads (B); then
select OHMS. The multimeter should show 5
ohms at full fuel position (C) and 95 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 bot-
tom of the fuel pump to latch in place; then con-
