Application
Models 8660 and 8680 are intended for stationary or mobile fuel tank applications containing middle distillates such as diesel and unless equipped with optional stainless steel support rods are not intended for use in fuels containing more than 10% ethanol or more than 30% bio-diesel. These gauges are not intended for use in pressure vessels. Models with optional stainless steel supports may also be used for fuels containing ethanol, bio-diesel and interstitial applications. The 8600 Series is not recommended for off-road equipment.

General Information
The 8660 spiral gauge is supplied with an easy to read, side-view fractional dial. The model 8680 spiral gauge is equipped with a standard top reading fractional dial.

All 8600 Series spiral gauges have a 1 1⁄2″ MNPT tank connection and are suitable for tank pressures up to 25 psig maximum. They are designed for top mounting in tanks up to 30″ deep are UL listed for flammable liquids.

Rochester gauge dials are magnetically driven. Fuel vapor cannot reach inside of the gauge lens and attack the UV rated lens material. Rochester gauges may be easily converted for remote output by simply installing the R3D Remote Ready dial and plugin Hall Effect sender module.
