6700 Series Gauge



Measures gasoline or diesel fuel levels in tanks on trucks, boats, generators, recreational vehicles, and other applications.

This gauge is built to the same dimensions as 6741-00259 (aka 6741-259) and the float arm has been improved by eliminating the 90-degree elbow at the float for easier installation and access.  The original part number was retired and a new part number was assigned by Rochester Gauges for the small batch that was manufactured for us.  The new part number is 6741-00443.  

The original 6741-259 did not include a gasket, dial capsule or mounting screws.  We have created bundles that allow you to select only the mechanical gauge assembly or add some or all of the other options as well.  If there is a combination of parts that you do not see listed but would like to have just let us know and we'll work with you to get you what you need.

General Information & Features

These top mounting magnetic liquid level gauges are built to the high standards of Rochester designed instruments. The construction permits the replacement of dials when necessary without releasing fumes or liquid to the atmosphere.

Both available dials are fractional and silicone-dampened, and are easily replaced by removing and reinstalling two screws. Rochester’s rugged gear drive incorporates shrouded, stainless-steel, beveled gears designed to work out any loose particles that might affect gear function. Sealing between the gauge and the tank is achieved through the use of the 0015-00423 Buna-N gasket.

General Specifications*
