Sierra 80150P Heavy Duty Fuel Gauge, 2 Inch, 12 Volt, for Inboard and Diesel Engines

The Sierra 80150P is a heavy duty 2 inch fuel gauge built for inboard and diesel engine applications where a reliable, easy-to-read fuel level readout is essential. It is part of Sierra's Heavy Duty instrumentation line, designed to withstand the vibration, moisture, and temperature swings common in marine and diesel engine compartments. The gauge runs on a 12 volt electrical system and uses an electromechanical movement to translate sender signal into a fuel level reading on the dial face.

Construction includes a stainless steel housing for corrosion resistance in the harsh marine environment, matching the durability standard Sierra applies across its engine and drive parts. The compact 2 inch dial size makes it suited for helm panels and instrument clusters where space is limited, and it is intended to be paired with a compatible fuel sending unit for accurate readings. As with other products in Sierra's gauge lineup, this fuel gauge is built to meet or exceed the performance of the original equipment part it replaces.

Frequently Asked Questions

What size is the Sierra 80150P fuel gauge? The Sierra 80150P has a 2 inch dial, sized to fit compact helm panels and instrument clusters.

What voltage does this fuel gauge run on? It operates on a 12 volt electrical system, matching standard inboard and diesel engine setups.

What engines is the Sierra 80150P designed for? This gauge is built for inboard and diesel engine applications rather than outboard installations.

What material is the Sierra 80150P fuel gauge made from? The housing is stainless steel, chosen to resist corrosion in the marine environment.

Does the Sierra 80150P include a fuel sending unit? No, the 80150P is the gauge itself; it requires a compatible fuel sending unit, sold separately, to provide the level signal.

Is the Sierra 80150P an electromechanical or digital gauge? It is an electromechanical gauge, using a physical needle movement driven by the sender signal rather than a digital display.

How much does the Sierra 80150P weigh? The gauge weighs 0.5 pounds.

What are the dimensions of the Sierra 80150P? Item dimensions are 3 x 3 x 5 inches, with package dimensions of 8.4 cm L x 12.5 cm W x 16.5 cm H.

Is the Sierra 80150P genuine Sierra equipment? Yes, the 80150P is a genuine Sierra Heavy Duty instrumentation product, engineered to meet or exceed the original equipment part it replaces.

Can the Sierra 80150P be used on gasoline inboard engines as well as diesel? Yes, the 80150P is designated for inboard and diesel engine applications, covering both use cases.

Is the Sierra 80150P part of a larger gauge series? Yes, the 80150P belongs to Sierra's Heavy Duty instrumentation lineup, which also includes related temperature, oil pressure, and tachometer gauges.
