See the Important Safety and Product Information guide in the product box for product warnings and
other important information.
The GFS 10 provides fuel-ow (volume/time) information for various screens, data elds,
or digital gauges of NMEA 2000
®
-compatible and Garmin
®
CANet
®
-compatible connected
display devices. For a list of compatible Garmin chartplotters and devices, visit
www.garmin.com.
Important: This document provides specic conguration information for the GFS 10
using your NMEA 2000-compatible or Garmin CANet-compatible display device (such as
a GMI
™
10 or GPSMAP
®
545). To access the NMEA 2000 or CANet device conguration
menu on your display device, consult the documentation provided with your display
device.
CAUTION: The GFS 10 is a sensor that helps you better determine the amount of fuel
used on your boat, and you should not rely solely on the GFS 10 for fuel-level information.
Carefully compare information displayed on the unit to all available fuel-level instruments
and sources.
Troubleshooting Fuel Gauge Type
When wired to a fuel gauge, the gauge type defaults to Auto Detect. If the fuel-level
reading on your Garmin chartplotter or marine instrument changes with the engine RPM,
the GFS 10 could be detecting the wrong type of gauge.
NOTE: The fuel level changes with the motion of the boat. Perform this test when the boat is
not moving.
To test the gauge-type setting:
1. When the boat is not moving, put the engine in neutral.
2. Use the throttle to increase the engine RPM. If the fuel-level reading changes with the
engine RPM, change the gauge type.
To change the gauge-type setting:
1. WhileviewingtheNMEA2000ortheCANetdevicecongurationmenu,selectthe
GFS 10 device.
2. Select Cong > Gauge Type.
3. Choose 1 Coil or 2 Coil and repeat the gauge-type setting test.
Troubleshooting the Fuel-Flow Rate
If the fuel-ow information received from the GFS 10 appears inaccurate, you can
manually adjust the fuel-ow reading.
To adjust the fuel-ow rate:
1. WhileviewingtheNMEA2000ortheCANetdevicecongurationmenu,selectthe
GFS 10 device.
2. Select Cong > Flow Adjustment.
3. Enter a positive or negative adjustment.
EXAMPLE: When you set the Flow Adjustment to +10% , a ow reading of 20 gal./hr.
(75 l/h) would change to a reading of 22 gal./hr. (82.5 l/h), because 20 gal. × 110% = 22 gal.
(75 l × 110% = 82.5 l).
Restoring Factory Default Settings
You can restore factory default settings to the GFS 10. You will lose all custom
conguration and calibration settings when you restore factory default settings.
To restore factory default settings:
1. WhileviewingtheNMEA2000ortheCANetdevicecongurationmenu,selectthe
GFS 10 device.
2. Select Cong > Factory Defaults.
