Installation Do’s & Don’ts
Do Don’t
Always use a Fuel Proof Pipe Thread Sealant
when assembling fittings into fuel system
components, (Locktite PST, Rector Seal, or
equivalent).
Never use Teflon Tape!
Use thin wall, low pressure,
NPT or NPTF hose barb fittings.
If possible avoid using JIC or SAE swivel
fittings. If used, always install Copper AP-50
sealing washers or Flaretite fitting seals onto the
JIC or SAE swivel fittings male end.
Double clamp all hose barb fittings.
Minimize the use of 90º elbow fittings.
Install Sensors as far from the engine as practical.
Fuel must travel, “Up-hill” at least 1 or 2 inches
after leaving the Return Sensor. Install Return
Sensors downstream of Pressure Regulator Valves.
If possible, try to avoid bolting or mounting
sensor(s) directly onto the engine.
Always install Diesel Forward Sensor/Pulsation
Damper assemblies and Gasoline Sensors on the
Vacuum or Inlet side of all Fuel Pumps.
Do Not Exceed the Forward or Return
Sensor/Pulsation Damper Assembly’s Tested
Operating Pressure of 100 PSI.
Always use 30-micron primary filters on Diesel
systems. 20 and 10-micron filters are
acceptable if required by the engine manufacturer.
Avoid 2 or 5-micron primary filters.
Wire with Shielded Cable on Diesel installations.
If possible use a dedicated shielded wire pair for
Magnetic Pickup Tachometer Senders.
Never use unshielded wires on
Magnetic Pickup Tachometer Senders.
Connect all Negative wires to a Battery Minus
Buss or directly to the Battery’s Negative
Terminal.
Connect or, “Ground” wire shields / shield drains
to the engine block or vessel bonding system.
Never connect Negative, (Battery Minus) wires
to the Hull, Engine Block, or other machinery.

FloScan’s Data (+) to the GPS signal output.
Connect Data (–) to a Battery Minus buss.
Do not connect FloScan’s Data (–)
to the GPS Data (–).
