Step 1: Installing the GFS 10 in the Fuel Line
Ensure the fuel line is drained, and use a hose cutter or knife to cut the fuel line where you want to install the GFS 10. Use the included hose
clamps to secure the fuel line to the GFS 10. Do not over-tighten the clamps. Inspect your fuel system and connections regularly.
Notes:
• Install the GFS 10 as far from the engine as practical.
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 line, 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.
• Install the GFS 10 in a location above the maximum fuel level of the fuel tank.
• Install the included fuel filter in the fuel line between the fuel tank and the GFS 10. Always have a spare metal
available.
• If additional fuel hose is needed when installing the GFS 10 and fuel filter, use
" (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 included the 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.
Use the included screws to mount the GFS 10 and the in-line fuel filter. Use the Drill Size Table to determine the
appropriate pilot hole.
