Review SIERRA Fuel Tester Replaces Mercury fits MARINE

The Sierra 18-79816 Marine Fuel Tester is a must-have tool for boat owners and marine technicians to ensure the optimal performance and health of their marine engines. Manufactured by Sierra Instruments, this fuel tester is specifically designed to work with Mercury branded engines, including those using the Mercury 91-879172T28 fuel filter.

This handheld fuel tester is compact and portable, making it easy to carry on board or take with you to the marina. Its rugged construction can withstand the rigors of marine environments, including exposure to sunlight, saltwater, and harsh chemicals. The tester features a large, easy-to-read digital display that shows real-time results for critical fuel parameters.

The Sierra Marine Fuel Tester measures important fuel quality indicators such as water content, diesel fuel temperature, and fuel flow rate. The water content measurement is particularly crucial as even small amounts of water in marine fuel can lead to significant engine damage. The tester can detect as little as 5 parts per million (ppm) of water in the fuel, ensuring that you can identify and address any water contamination issues before they become major problems.

The diesel fuel temperature measurement helps to ensure that the fuel is within the recommended temperature range for optimal engine performance. The fuel flow rate measurement is useful when diagnosing fuel system issues or optimizing engine performance.

The tester is simple to use, requiring only a few steps to perform a fuel test. First, connect the tester to the Mercury 91-879172T28 fuel filter using the included adapter. Next, press the start button and allow the tester to stabilize. Once stabilized, the digital display will show the water content, diesel fuel temperature, and fuel flow rate measurements.

In summary, the Sierra 18-79816 Marine Fuel Tester is an essential tool for boat owners and marine technicians who want to ensure the optimal performance and health of their Mercury-powered marine engines. Its rugged construction, ease of use, and ability to detect even small amounts of water in fuel make it an indispensable addition to any marine toolkit.
