INSTALLATION PLANNING
!
READ ME FIRST - Detailed Mechanical & Electrical Planning Saves Installation Hours!
!
FloScan systems are not difficult to install. Installing one requires only basic electrical & mechanical skills. With forethought and
planning, your system will be installed with few problems.
I. Installation Preparation:
Review the pre-installation booklet and mechanical installation instructions, then survey your vessel. Determine where the
Sensor(s), Pulsation Damper(s), NMEA 2000 Interface Hub, Fuel-Tron, & Fuel-Tron Screen Selection Switch are to be mounted.
Place them at their approximate locations. Measure fuel line lengths between system components, (Primary Filter, Sensor(s),
Damper(s), Engine, and Fuel Tank. Determine fitting sizes and type of fittings needed for each plumbing connection, (JIC, SAE,
NPT, NPTF, or Hose Barb).
FloScan Series K High Flow, Diesel system components have 1”, and ½” Female NPT ports.
FloScan Series K Standard Flow, Diesel, system components have ¼” Female NPT ports.
FloScan Gasoline High Flow, system components have ½” Female NPT ports.
FloScan Gasoline Standard Flow, system components have ¼” Female NPT ports.
Gasoline Fuel Systems: USCG requires Type A-1 Fuel Hose to be installed between the fuel tank and the engines’ fuel inlet
connection. Type B-1 may be used if certain safety requirements are met, (33 CFR, Subpart J, 183.558). 33 CFR Subpart J,
183.532 require hose clamps to be made from a corrosion resistant material. To meet American Boat & Yacht Council, (ABYC)
standards, the clamps must be made from a corrosion resistant metal, (ABYC, H-24.11.1).
Diesel Fuel Systems: Fuel hose and fittings can comprise a significant portion of the total installation cost. Costs for A-1 Fabric
Braid hose & hose barb fittings are approximately 1/3
rd the cost of Steel Braid hose & JIC fittings. Both Type A-1 fabric braided
hose and wire braided hose meet exactly the same regulatory requirements, (USCG & ABYC) but fabric braid installation costs
are far less.
Fabric Braid A-1 fuel hose generally uses hose barb fittings. These come in a wide range of Hose Barb to Male NPT, JIC, SAE,
& NPTF sizes and combinations. Example: 12 HB X 16 MNPT, (3/4” Hose Barb by 1” Male NPT). Steel Braid, Aeroquip type
A-1 fuel hose have reusable hose end fittings. Aeroquip type hose ends come in a wide variety of types and sizes, (JIC, SAE,
NPT, & NPTF).
Review the electrical installation instructions.
II. Mechanical Installation:
Install or mount the Sensor/Pulsation Damper assemblies, or Sensors, NMEA 2000 Interface Hub, Fuel-Tron and Switch.
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.
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.
