2-Wire Fuel Level Sender 240-33 Ohm
Note: Includes gasket.
NOTE: These senders can only be trimmed to a minimum of half their original length, Such as 6" for a 12" Sender and 12" for a 24" sender and so forth. 48" and 60" are made to order and have 3 week lead time.
These senders will NOT work with digital gauges. These senders will not work with dual station or two gauges trying to read from one sender. They are designed for analog type marine fuel level gauges. Use the 3-wire sender for digital gauge applications.
IMPORTANT: These senders must be re-calibrated if trimmed. THEY DO NOT auto calculate full and empty! See Instructions. The senders auto calibrate to type and grade of gas used.

How It Works
Measurement is done by series of reed switches positioned inside the level tube. A float with built in magnets then triggers the reed relays generating a potential - free resistance with an ohm value that increases or decreases. Resistance output is fully customizable. The float is the only moving part of the sensors, thereby minimizing potential mechanical failures. All sensors are fully insulated to protect against voltage inside the tank.
