Part# 10-02045
MFR Model# 9341-R7090


These fuel senders are designed for top mounting in unpressurized aluminum, stainless steel, or plastic fuel tanks in all types of marine vessels. They include special features and protection from corrosion problems (internal and external to the fuel tanks) which make them the quality standard for the industry.

General Information & Features
Standard configuration, with the lead hole at 12:00, has the float arm swinging at 3:00.
The float arm on this sender is 24" [609mm] long measured from the pivot point allowing it to be cut to an appropriate length to gauge any tank depth from 6" [152mm] to 25" [635mm]. The float and the washers are furnished unassembled to the float arm. The cutting and crimping process is to be done prior to the float assembly.

The fuel sender is equipped with a thick film resistance card with a range of 0 to 90.

The recommended gasket for use under the head is made of nitrile rubber and must be ordered separately.

The shipment arrived on different days where the metal rods package was not sealed/secured properly which allowed those to protrude out.

Unfortunately, after extensive testing with more than one fuel gauge, this unit did not function.
