2-Wire Fuel Level Sender

  • With a double tube design, these senders measure the amount of air trapped between the tubes providing you accuracy you  can't get from float style senders

    • (240 ohm empty and  33 ohm full)
  • Will work for gasoline or diesel fuel

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. These senders will NOT work with digital gauges. 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.
