Fuel Sending Unit

Connect ohmmeter lead to ground terminal or housing, and the other lead to resistance terminal. With float at empty position, ohmmeter should read 60-86 ohms. With float at full position, resistance should be 8-12 ohms. Resistance change should be smooth as float is moved. If specifications are incorrect or resistance change readings jumped erratically, replace sending unit.
