2-Wire Fuel Level Sender 240-33 Ohm

2-Wire Fuel Level Sender 240-33 Ohm

• 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
• For use with 240-33 ohm gauges
• (240 ohm empty and  33 ohm full)
• Will work for gasoline or diesel fuel
• 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.
• Gasket Included
• No Mounting Hardware included.

Note: Includes gasket.

*****WARNING NOTE***** Installer error NOT READING INSTRUCTIONS is the number one reason for fuel sender problems and abnormalities. These units require proficient mechanical background to cut, program, and install. These are the best senders on the market and have been in use 30 years. They require proper installation to work.

• NO!  This is a GAS Sender it will NOT read water, or oil!
• NO!  You cannot wire or daisy chain 5 fuel senders together and get one reading
• NO! It reads in OHMS NOT Millivolts, it is NOT digital output 
• NO! It CANNOT calibrate an empty or partially filled tank to a full reading. TANK MUST BE FULL 
• NO! It will not work in your car/airplane with 0-80 OHM gauges these are marine 240-33 OHM senders only.
• NO! It will not defy gravity! If your sender is mounted in the rear of the tank and the bow is in the air it will show more fuel than you have! Boat must be level to earth for accurate reading!
• NO! You do not design your own program sequence you follow the instructions.
• YES!  People have done all of these things wrong...

NOTE: These senders can only be trimmed to a minimum of half their original length.

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.
