Installation Instructions
Hoses and Fittings:
Use only USCG Approved fuel lines. Make
sure that the fuel line routing is not touching any sharp edges.
Fittings should be full flow design and not restricted tight 90
degree elbows.

Special Fuel Instructions for 6.2 LT4 Engines
Fuel Supply:
The fuel supply pick up tube, fuel lines and
fittings shall be no smaller than 1/2” inside diameter between the
fuel tank and the Aero Motive high-pressure fuel pump. The fuel
pump must also have the supplied serviceable 100 Micron filter
installed on the inlet side of the fuel pump. Some installations
use an in-tank fuel pump. In these cases, the 100 micro filter or
water separator is not necessary. Always mount a 10 micro filter
between the pump and the injectors. When using an auxiliary
engine such as an outboard motor, never plumb or tee into the
main engine fuel system. The auxiliary engine shall have its
own fuel pick up tube and fuel filter/water separator from the
fuel tank. Plumbing into the main engine fuel supply will cause
damage to the engine and fuel pump system.
Fuel Pump Location:
If the Aero Motive fuel pump is relocated
from its mounting location on the engine it must be placed as
close to the fuel tank as possible. The maximum distance from
the fuel tank pick up tube should be no more than 30”. The fuel
pump must also be placed as low to the bottom of the fuel tank
as possible. Using the lowest point on the bottom of the fuel tank,
mount the fuel pump no more than 12” above the bottom of the
fuel tank. USCG REGULATIONS require that the fuel pump should
be within 12” of the engine (excepting Airboats).
The Racor fuel/water separator should NEVER be placed on the
outlet side of the Aero Motive fuel pump. The fuel filter/water
separator should also be mounted within 12” from the bottom
of the fuel tank.
