Use the Garmin® GFL 10 adapter to adapt analog information provided by a fluid-level sensor
on your boat to your NMEA 2000® network. The GFL 10 adapter allows you to observe
fluid-level information on compatible Garmin display devices connected to your NMEA 2000
Compare the contents of this package with the packing list on the box. If any pieces are
missing, contact your Garmin dealer immediately.

Warning: When connecting the GFL 10 adapter directly to the sensor on a fuel tank, make the
connection to the sender on the tank before connecting the adapter to the NMEA 2000 network.
This will reduce the risk of sparks near the fuel tank.
notiCe: After connecting the adapter to the gauge or sensor, cover any exposed wires with heat-
shrink tubing.
Connecting the GFL 10 Adapter to a NMEA 2000 Network
After you have connected the GFL 10 adapter to the analog gauge or to the sender, connect it
to the existing NMEA 2000 network on your boat. If you do not have a NMEA 2000 network
on your boat, you must build one. For more information on NMEA 2000 and to purchase
To connect the GFL 10 adapter to your existing NMEA 2000 network:
1. Determine where to connect the GFL 10 adapter to your existing NMEA 2000 backbone.
2. Disconnect one side of a NMEA 2000 T-connector from the backbone. To extend the
NMEA 2000 backbone, connect a NMEA 2000 backbone extension cable to the side of the
disconnected T-connector.
3. Add the included T-connector for the GFL 10 adapter to the NMEA 2000 backbone by
connecting it to the side of the disconnected T-connector.
4. Connect the NMEA 2000 connector on the GFL 10 adapter to the T-connector added in
step 3.
5. (Optional) If the GFL 10 adapter cannot connect directly to the NMEA 2000 backbone, route
a NMEA 2000 drop cable (not included) to the bottom of the T-connector added in step 3.
Use a drop cable with a length up to 20 ft. (6 m). Connect the drop cable to the T-connector
and to the NMEA 2000 connector on the GFL 10 adapter.
notiCe: If you have an existing NMEA 2000 network on your boat, it should already be
connected to power. Do not connect an additional NMEA 2000 power cable to an existing NMEA
2000 network, because only one power source should be connected to a NMEA 2000 network.

Configuring the GFL 10 Adapter
notiCe: This section provides specific configuration information for the GFL 10 adapter
using your compatible Garmin display device. To access the NMEA 2000 configuration menu
on your display device, consult the documentation provided with your display device.
Configuring the NMEA 2000 Fluid Type
You can indicate the type of fluid that is in the tank with which each GFL 10 adapter is
associated.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
•
•
For most Garmin chartplotters, select Review > N2K Fluid Type.
For other Garmin marine devices, select Config > N2K Fluid Type.
3. Select a fluid type.
4. Select OK.
Configuring the Tank Number
If your boat has multiple fluid tanks, you can indicate which tank each GFL 10 adapter is
associated with.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
•
•
For most Garmin chartplotters, select Review > Tank Number.
For other Garmin marine devices, select Config > Tank Number.
3. Select a tank number.
4. Select OK.

GFL 10 Installation and Configuration Instructions
Configuring the NMEA 2000 Tank Capacity
You can indicate the capacity of the fluid tank that the GFL 10 adapter is associated with.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
•
•
For most Garmin chartplotters, select Review > N2K Tank Capacity.
For other Garmin marine devices, select Config > N2K Tank Capacity.
3. Select the tank capacity.
4. Select Done.
Calibrating the Fluid Level
To use the GFL 10 adapter, you must calibrate the fluid level of the tank that the adapter is
associated with, using a minimum of two calibration points. The greater the number of fluid
calibration points, the greater the accuracy of the reading on the fluid-level gauge.
1. Turn the boat ignition key to the On position (not Start).
2. From the NMEA 2000 Devices list, select the GFL 10 device.
3. Select an option:
•
For most Garmin chartplotters, select Review > Level Calibration > Add Calibration
Point.
•
For other Garmin marine devices, select Config > Level Calibration > Add Calibration
Point.
4. Select the percentage of fluid currently in the tank, based on the total tank capacity.
5. Select Done.
6. Change the level of the fluid in the tank.
7. Select Add Calibration Point.
8. Select the percentage of fluid currently in the tank, based on the total tank capacity.
9. Select Done.
10.Repeat steps 6 through 9 to add additional, optional fluid-level calibration points.
Troubleshooting the Tank Number
If multiple GFL 10 adapters are assigned to the same NMEA 2000 fluid type, each adapter is
assigned a unique tank number automatically. If the “Invalid NMEA 2000 tank configuration”
error message appears, you must assign a unique tank number to each adapter.
For example, if two adapters are assigned the NMEA 2000 fluid type value of Live Well and the
error message appears, you must assign each adapter a unique tank number.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
•
•
For most Garmin chartplotters, select Review > Tank Number.
For other Garmin marine devices, select Config > Tank Number.
3. Select a tank number.
4. Select OK.

Troubleshooting the Gauge Type
When connected to a gauge, the GFL 10 adapter gauge type is set to auto Detect by default,
and the adapter automatically detects the type of gauge it is connected to. If the fluid-level
reading on a connected Garmin chartplotter or marine instrument changes with the engine
RPM, the adapter may be detecting the wrong type of gauge.
note: The fuel level changes when the boat is moving. Test the gauge-type setting 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 fluid-level reading changes with the
engine RPM, change the gauge type.
To change the gauge type:
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
•
•
For most Garmin chartplotters, select Review > Gauge Type.
For other Garmin marine devices, select Config > Gauge Type.
3. Select an option:
•
•
•
To automatically detect the gauge type, select Auto Detect.
To indicate a one-coil gauge, select 1 Coil.
To indicate a two-coil gauge, select 2 Coil.
4. Perform the gauge-type setting test.
Resetting the Fluid Level Calibration
You can reset the fluid-level calibration of the tank that the GFL 10 adapter is associated with.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
•
•
For most Garmin chartplotters, select Review > Level Calibration.
For other Garmin marine devices, select Config > Level Calibration.
3. Select Reset Calibration.
4. Select Yes.
5. Calibrate the fluid level.
