Reed Array Fuel Sender with Adjustable Float Arm


The Reed Array line of fuel senders fit 4” [101.6 mm] to 24” [609.6 mm] tank depths. The sender is designed for top mounting in aluminum, plastic, or stainless steel fuel tanks in all types of applications. It includes special features and protection from corrosion (internal and external to the fuel tank) which makes it the quality standard for the industry.

General Information & Features

The Reed Array Sender comes standard with a SAE 5 hole mounting bolt pattern with the lead hole at 12:00 and the float arm at 3:00. The head and support are molded from UV stabilized Acetal and is suitable for medium-duty off-road conditions. The electrical circuit is sealed to protect components from fuel, contaminants, water and the molding-curing process (out-gassing). This Reed Array Sender offers dependable, long-lasting Reed Switch and magnet technology. The sender is suitable for gasoline, ethanol, diesel, bio-diesel and non-potable water.

Industry standard output: 240-30 ohms. The close tolerances held on this series of Reed Array Fuel Level Sender will provide the proper signal for any of the popular 2” [50.8 mm] panel mounted receivers.

The float arm on this sender is 23” [584.2 mm] long measured from the pivot point to float, allowing it to be cut to an appropriate length to gauge any tank depth from 4” [101.6 mm] to 24” [609.6 mm]. The bending process is to be done prior to the float assembly. After installation of float wire, attach push nut to wire and clip wire.

Three year limited warranty.
