4 BOLT GAUGE WITH ADJUSTABLE FLOAT FOR LOW PRESSURE TANKS (0 – 25 PSIG)
Ordering Notes: Please allow 1/2” or more for clearance between float arm and bottom of tank. For example, a tank depth of 30” should have a gauge length of 29-1/2”.
Application
The 6500 Series Senior gauges are designed for use in low pressure tanks 0-25 psig [0-1,7Bar] containing diesel fuel, gasoline, fuel oil and lubricating oils.
Used in many applications such as construction equipment, stationary generators, boats, farm equipment and home heating.
General Information & Features
The 6500 Series Adjustable Senior gauges are available in gear-action models for top mounting.
The standard float is nitrile rubber. The gauge is mounted to a mating Senior flange 2 1⁄2″ bolt circle [63,5mm] using four 1⁄4″-28 x 9⁄16″ long bolts. The included gasket is Buna-N.

This 6580-151 includes our Cut & Crimp service where we adjust the float arm to the length selected from the drop-down menu. This is the measurement from the underside of the gauge head to the end of the float. Gauge lengths over 33" are made by adding a float arm extension. If you would like a different length, just give us a call and we can probably take care of it for you. (804)462-5679.
