TESTING



See Figures 1 and 2


CAUTION
Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.

Using an ohmmeter, check the resistance between terminals G and E . When the float rod in the full (up) position, the resistance should be between 4 and 8 ohms. When the float rod is in the empty (down) position, there should be between 78 to 85 ohms of resistance.

For vehicles with digital instrumentation, the resistance between terminals G and E should be between 15 to 18 ohms when the float rod is in the full position. With the float rod in the empty position, there should be approximately 929 and 1,009 ohms of resistance.
