Fuel Sensor Installation Instructions
To obtain the best possible performance, install your GFS 10 Fuel Sensor according to the following instructions. If you experience difficulty
during the installation, contact Garmin Product Support, or seek the advice of a professional installer.
The GFS 10 will communicate with NMEA 2000- or Garmin CANet-compatible chartplotters and displays. Refer to
of compatible devices.
Warnings:
• The GFS 10 is designed for use with gasoline-engine fuel systems.
Do not use the gFs 10 with diesel-engine fuel systems. Do not use
the gFs 10 with fuel that contains more than 10% ethanol such as E85 fuel.
• The GFS 10 is designed for use with single-line fuel systems. Do not install the GFS 10 on engines with a return line to the fuel tank. On
pressurized fuel injected systems, the GFS 10 must be mounted on the low pressure side of the high-pressure fuel pump. Engine-mounted
fuel reservoirs may cause erratic flow readings. The GFS 10 is not recommended for systems with large engine-mounted fuel reservoirs.
• Gasoline is extremely flammable. If possible, drain the fuel hose before you start, or shut any flow valves located near the tank. Keep
sparks and flame away from the work area.
• Work in a well-ventilated area.
• After installation, be sure to clean up any spilled fuel, and dispose of any spilled fuel in accordance with local laws.
• Periodically check the GFS 10 installation for leaks, and repair any leaks before using your boat.
