III. Plumbing:
Fabric Braid A-1 Fuel Hose: Install the correct HB X MNPT fitting into each fuel system component, Tank, Manifolds, Filter,
Sensor(s) Damper(s) and Engine. Assemble fittings using a fuel proof pipe thread sealant. Never use Teflon Tape. Referring to
the Fuel Flow Schematic, run the fuel hose between system components. Cut to correct length with a pocket or razor knife. Hoses
should not be twisted, have adequate slack, an ample radius at all bends and be supported at reasonable distances, approximately
2-4 feet. When clamping hose onto the barbs, use 2 narrow or 1 wide stainless hose clamp on each hose end.
Tools required are combination wrenches, screwdriver, knife, drill motor, bits, and punch. This should take approximately 1 to 2
hours on gasoline and single diesel systems, no more than 3 to 4 hours on twin diesel systems.
Wire Braid A-1 Aeroquip Type Fuel Hose: Install the correct fitting into each fuel system component, Tank, Manifolds, Filter,
Sensor(s) Damper(s) and Engine. Assemble fittings using a fuel proof pipe thread sealant. Never use Teflon Tape. Referring to
the Fuel Flow Schematic, run the fuel hose between system components. Cut to correct length and install hose ends.
• If you choose to do this yourself, rent a hose-cutting tool and purchase a tube of assembly lubricant.
• Most dealers will cut and assemble both hose ends for $10 per hose. Some charge as much as $40.
Hoses should not be twisted, have adequate slack, an ample radius at all bends and be adequately supported at reasonable
distances, approximately 2-4 feet. AP-50 copper sealing washers or Flaretite fitting seals may be required to seal JIC & SAE
fittings.
Tools required are combination wrenches, screwdriver, drill motor, bits, and punch. This will take approximately 4-6 hours on
single and twin Diesel systems.
IV. Electrical Installation:
Run cables between Sensor(s), J-Box, (If used) and Instrument(s). Cables must be adequately supported at reasonable distances,
approximately 2-4 feet.
Tools required are a screwdriver, diagonal pliers, and possibly a wire snake. This usually takes 1 to 2 hours. Difficult runs take
longer.
Wire Terminations—Referring to the wiring diagram. Connect Sensor, Instrument and Switches to their respective wires with
crimp type butt or ring connectors. Always cover connectors and wire ends with heat shrink tubing.
Tools required are a screwdriver, diagonal pliers, wire strippers, pliers, and heat gun. This usually takes 1 to 2 hours on Gasoline
systems, 2 to 4 hours on Diesels. Add an additional hour for confined workspaces.
Isolated Ground Electrical Systems: FloScan manufactures 12 VDC to 12 VDC, (PN 7000-097-00) and 24 VDC to 12 VDC,
(PN 7000-096-00) Isolated Ground Power Supplies / Voltage Reducers. These power supplies electrically isolate the FloScan
system from ship’s power and are used by the Washington State Ferry System and other large steel and aluminum vessel
operators. Additionally mounting sensors onto a non-conductive surface and using short lengths of non-metallic fabric braid fuel
hose to connect them further isolates the system.
Diesel Fuel is non-conductive but does contain a, “Static Electricity Dissipater” additive to minimize the risk of fuel tank fires
and explosions. Even with this additive, the electrical resistance of Diesel Fuel is extremely high and can be considered non-
conductive. Installing the FloScan system with Isolated Ground power Supplies, Non-Conductive Sensor Mounting Surfaces and
Fabric Braid Fuel Hose will electrically isolate it from the vessel’s hull.
V. Pre-Startup:
• Always Prime the fuel system before Engine Start-Up. This prevents your engine from becoming air-bound.
If you have an electric priming or boost pump, circulate fuel for 10 minutes while checking for leaks. If the fuel system does not
have an electric priming pump, use the engine's manual pump. Before starting, slightly open or crack the lift pumps' outlet fitting.
Pump until all air is purged at the lift pumps' outlet. Before start-up, verify that all fuel system fittings are tight.
