Do not install the GFS 10 directly on the engine or where it could be subjected to excessive heat or vibration. Do not install the GFS 10 between the engine and the priming bulb (if applicable). · When placing the GFS 10 in the fuel hose, be sure the direction of flow, as indicated by the arrow, points toward the engine. · Install the GFS 10 so the fuel flows in an upward direction through the GFS 10. This will prevent errors caused by air bubbles. Ensure that the fuel hose is drained, and use a hose cutter or a knife to cut the fuel hose where you want to install the GFS 10. Use the included hose clamps to secure the fuel hose to the GFS 10. Do not overtighten the clamps. Inspect your fuel system and connections regularly. Engine GFS 10 To power and data connections Fuel filter Fuel tank · Install the GFS 10 in a location above the maximum fuel level of the fuel tank. · Install the included fuel filter in the fuel hose between the fuel tank and the GFS 10. A sticker on the filter indicates the direction of fuel flow. Always have a spare metal 3/8 in. (9.5 mm) in-line fuel filter available. · If additional fuel hose is needed when installing the GFS 10 and fuel filter, use 3/8 in. (9.5 mm) US Coast Guard type A1 fuel hose. · Have two 3/8 in. (9.5 mm) in-line, fuel-line splice barbs available. This allows you to remove the GFS 10 and the fuel filter, in case of an emergency, and maintain normal engine operation. · Be sure to clean up any spilled fuel. Step 2: Mounting the GFS 10 and Fuel Filter The GFS 10, the in-line fuel filter, and the fuel hoses must be mounted to your boat. A bracket for the GFS 10, cable ties with eyelets for the in-line fuel filter and hoses, and mounting screws are provided. When mounting the GFS 10 to a solid structure on your boat, use the included bracket to secure the GFS 10 device, and use two included cable ties to secure the hose on either side of the GFS 10. When mounting the in-line fuel filter to a solid structure on your boat, use two cable ties around the fuel filter and two cable ties around the hose on either side of the fuel filter. If you are unable to use the included bracket to secure the GFS 10 to a solid surface, use an included cable tie to secure the GFS 10 device to a bundle of cables or other hoses. Use the included screws to mount the GFS 10 and the in-line fuel filter. Drill a 1/8 in. (3.2 mm) pilot hole for each screw. If you are mounting the GFS 10 on fiberglass, use a countersink bit to drill a clearance counterbore through the top gelcoat layer (but no deeper). This will help to avoid cracking in the gelcoat layer when the screws are tightened.

Optionally, the GFS 10 can be connected to the fuel gauge on your boat to read fuel-level data. The bare-wire cable contains the power and ground wires, as well as the wires you connect to your fuel gauge. Follow the wiring diagram to complete the connections. - 12 Vdc + Fuel gauge connection optional Ground Ignition Fuel Tank Level Sensor Battery To NMEA 2000 Network or CANet Bus Wire Color Red/White Fuse Black/White .25 A Grey Brown Orange Unconnected (when using NMEA 2000) IMPORTANT: · If you use a fuse block on your boat, cut the fuse holder from the power wire. Use a .25 A fuse in the fuse block. · Install the fuse holder as close to the battery as possible. If an extended run of wire is needed, add 24 AWG wire between the fuse holder and the GFS 10, not between the fuse holder and the battery. · DO NOT install the fuse holder near the gas tank. · If you do not connect the GFS 10 to a fuel gauge or level-sensor on a fuel tank, connect the brown wire to ground, and leave the grey wire unconnected. Notes: · Consult the owner's manual provided by your boat manufacturer to determine the ground, ignition, and level-sensor connections on your fuel gauge. Often, the ignition connector is labeled "I" or "+", and the level-sensor connector is labeled "S." · If you do not have a fuel gauge, but you do have a fuel tank with a level sensor, connect the brown wire to the "+" terminal of the level sensor at the tank. DO NOT install the fuse holder near the tank--extend the brown wire to the tank with 24 AWG wire. Complete this connection before completing any other wiring connections to reduce the risk of a spark near the fuel tank. Leave the grey wire unconnected. · If you are using NMEA 2000, be sure to leave the orange wire unconnected. Multiple GFS 10 Devices If your boat has more than one engine or fuel tank, you will need multiple GFS 10 devices. Each GFS 10 can function as one flow sensor and one level sensor. You need one GFS 10 flow sensor for each engine, and one GFS 10 level sensor for each fuel gauge or for each fuel tank that has a level sensor. Depending on your boat, you may use only the flow-sensing capabilities of additional GFS 10 devices. Flow Sensing Multiple engines Multiple fuel tanks for one engine Level Sensing Multiple tanks with one fuel gauge and a manual switch Multiple fuel tanks with multiple gauges Multiple fuel tanks with no fuel gauge One GFS 10 per engine­up to four engines One GFS 10 per engine­install after the tank switch One GFS 10 wired to the fuel gauge One GFS 10 per tank­wired to each gauge­up to two tanks One GFS 10 per tank­wired to the level sensor (if available)­up to two tanks notE: When using multiple GFS 10 units on multiple engines, it is normal to read different fuel flow rates on each GFS 10 unit. Similar engines do not always consume fuel at the same rate. GFS 10 Fuel Sensor Installation Instructions 3 Step 4: Connecting the GFS 10 to Your Chartplotter Connecting the GFS 10 through NMEA 2000 The GFS 10 is packaged with a NMEA 2000 T-connector. The GFS 10 has a built-in NMEA 2000 drop cable. Use these two components to connect the GFS 10 to your existing NMEA 2000 network. If you do not have an existing NMEA 2000 network, you will need to install a NMEA 2000 network on your boat. For more information on NMEA 2000, visit www.garmin.com. To connect the GFS 10 to your existing NMEA 2000 network: 1. Determine an appropriate location to connect the GFS 10 to your existing NMEA 2000 backbone. 2. Disconnect one side of a NMEA 2000 T-connector from the backbone nearest to the location where you want to connect the GFS 10. If you need to extend the NMEA 2000 backbone, connect an appropriate NMEA 2000 backbone extension cable (not included) to the T-connector you disconnected. 3. Connect the included T-connector for the GFS 10 to the NMEA 2000 backbone. 4. Route the built-in drop cable on the GFS 10 to the bottom of the T-connector you added to your NMEA 2000 network. If the built-in drop cable is not long enough, you can add a drop cable extension up to 14 ft. (4 m). If more cable is needed, add an extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines. The GFS 10 transmits data to your chartplotter or Marine Instrument using either NMEA 2000 or Garmin CANet. Existing NMEA 2000 network (not included) T-connector (included) Drop cable (built-in) GFS 10 To power source/fuel gauge (leave the orange wire unconnected) Connecting the GFS 10 to a NMEA 2000 Network Connecting the GFS 10 through Garmin CANet The GFS 10 is packaged with a Garmin CANet adapter that you can use to connect the GFS 10 to your existing Garmin CANet bus. If you do not have an existing CANet bus, you will need to install a CANet bus on your boat with a Garmin CANet Kit (010-10742-00). For more information on Garmin CANet, visit www.garmin.com. To connect the GFS 10 to your existing CANet bus: 1. Determine the location on your CANet bus where you would like to connect the GFS 10. 2. Wire the CANet adapter to your existing CANet bus using the diagram below to make the appropriate connections. Follow the instructions included with the CANet Kit (010-10742-00) to determine whether a terminator is needed in the location where you install the GFS 10. 3. Route the built-in drop cable on the GFS 10 to the CANet adapter, and complete the connection.
