Using Fuel-Flow Information With a Garmin Chartplotter
or Marine Instrument
CautIon:
The Garmin chartplotter or marine instrument must be powered on to calculate
remaining fuel based on the fuel-flow rate.
Important
: When using the GFS 10 to calculate remaining fuel based on the fuel-flow
rate, you must specify the amount of fuel each time you add fuel to the tank.
To specify the amount of fuel added:
1. While viewing the fuel page or fuel instrument screen on your NMEA 2000 or CANet
device, select
Menu
.
2. Choose from the following options:
Fill Up Tank
—set fuel level to the maximum capacity.
Add Fuel to Boat
—specify the amount of fuel added.
Set Total Fuel Onboard
—specify the amount of fuel currently available in the fuel
tank or tanks.
Changing the Fuel Economy Source
The Garmin chartplotter or marine instrument requires a speed sensor in addition to the
GFS 10 to calculate fuel economy.
To change the fuel economy source:
1. While viewing the fuel page or fuel instrument screen on your NMEA 2000 or CANet
device, select
Menu
>
Fuel Economy Source
.
2. Select either
GPS Speed
or
Water Speed
to specify which speed sensor is used to
calculate fuel economy.

Using Fuel-Level Information With a Garmin Chartplotter
or Marine Instrument
To receive fuel-level information, connect the wiring harness on the GFS 10 to the fuel
gauge or fuel-level sensor of your boat according to the
GFS 10 Installation Instructions
.
To calibrate fuel-level information from the GFS 10:
1. While in still water, on the NMEA 2000 or CANet device configuration menu, select the
GFS 10 device that is connected to the fuel tank you want to configure.
tIp:
The serial number of each GFS 10 is shown on he NMEA 2000 or CANet device
configuration screen to help differentiate between multiple GFS 10 devices.
2. Select
Config
>
Level Calibration
>
Add Calibration Point
and enter a calibration
point that corresponds to the current fuel level in that fuel tank.
Entering more calibration points will provide a more-accurate reading. For example,
entering five calibration points (empty tank,
1
/
4
tank,
1
/
2
tank,
3
/
4
tank, and full tank) will
provide a more-accurate reading than entering two calibration points (empty tank and
full tank).
tIp:
For a quick calibration, start with an empty tank, and enter calibration points as you fill
up the tank.
To reset the fuel-level calibration:
1. While viewing the NMEA 2000 or the CANet device configuration menu, select the
GFS 10 device that is connected to the fuel tank you want to configure.
2. Select
Config
>
Level Calibration
>
Reset Calibration
.
Configuring Engine and Tank Information
If you have a multi-engine or a multi-tank setup on your boat, specify which engine or tank
is associated with each GFS 10.
tIp:
The serial number of each GFS 10 is shown on the NMEA 2000 or the CANet device
configuration menu to help differentiate between multiple GFS 10 devices.
To configure tank and engine information for the GFS 10:
1. While viewing the NMEA 2000 or the CANet device configuration menu, select the
GFS 10 device you want to configure, and select
Config
.
2. Select from the following options:
Engine Number
—for a multi-engine installation, assign the selected GFS 10 to a
specific engine.
Tank Number
—for a multi-tank installation, assign the selected GFS 10 to a specific
tank.
Tank Capacity
—define the fuel capacity of the fuel tank that the selected GFS 10 is
connected to.
