Installation Do’s & Don’ts
Do
Don’t
Use a Fuel Proof Pipe Thread Sealant when
assembling fittings into fuel system components,
(Locktite PST, Leak-Lock, or equivalent).
Never use Teflon Tape!
Use thin wall, low pressure, full flow type NPT or
NPTF hose barb fittings.
Don’t use Push-Lok, or Barb-Tite fittings.
Avoid using JIC or SAE swivel fittings. If used

(Connie seals) or fitting seals on fittings.
Double clamp all hose barb fittings.
Avoid using 90º elbow fittings.
Install Sensor(s) at a low point in the fuel system, as
far from the engine as practical. Fuel must travel,
“Up-hill” slightly after leaving the sensor. Verify
correct orientation and fuel flow direction.
If possible, avoid bolting or mounting sensor(s)
directly onto the engine.
Connect all, “Ground” wires to a Ground Buss, or
directly to the Battery’s Negative Terminal. Connect
or, “Ground” wire shields to the engine block.
Never connect Instrument or Sensor “Ground”
wires to the hull, engine block, or other
machinery.
