  • Works with DATCON, LIVORSI (or gaffrig newer than 1996), OMC, STEWART WARNER, TELEFLEX US GAUGE, AUTOMETER, FARIA, and Hardin Marine gauges. Does not work with any digital gauge. If you have a 240-33 ohm gauge that is not on this list you must use 3-wire sender instead.

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. 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.
