AirDog II, A6SABD340, DF-165 Air/Fuel Separation System, fits 1989-1993 Dodge 5.9L Cummins
(w/ adjustable regulator, preset @ 10-13psi)
NEW Quick Connect / Dis-Connect Fittings - Drops Installation Time 30-45 Minutes!
The new AirDog II Demand Flow Fuel Preporator
This new model Fuel Preporator
improves on the original by offering demand flow, so that the unit only
draws as much fuel from the tank - through the tank module - as is
required by the engine, and then returns only air and a dribble of fuel
to the tank. What does this mean? Connecting to the tank module means
there is no need to drill holes in the fuel tank to install an
aftermarket fuel draw straw, so installation with the included fittings
is QUICK and EASY. The AirDog II also features either a preset or
adjustable stainless steel pressure regulator. As always, all AirDog II units come complete with fittings, fuel lines, mounting brackets,
and full-color installation manual specific to each model truck.

Reliability
and Performance! Two powerful reasons to add an AirDog to your diesel
pickup! The AirDog provides the proper pressure/flow of fuel to your
diesel engine under virtually all operating conditions for PEAK
EFFICIENCY with CONSISTENT and MAXIMUM POWER OUTPUT!

Your High Performance
diesel engine demands higher fuel flows. Yet higher fuel flows increase
the vacuum at the fuel pump and agitation in the fuel tank. These
factors generate additional air/vapor in the fuel system preventing your
engine form producing maximum power and efficiency. Additionally,
air/vapor can cause galling and pitting of the injector barrel/plunger
assembly and also tip erosion.
The
AirDog eliminates the air in the fuel that robs your engine of
consistently greater performance and can also cause permanent damage to
your injectors. The AirDog also provides the fuel pressures and flows
your diesel engine needs to produce maximum power, any time, every time!
The
AirDog II, designed to operate at flows and pressures beyond the
maximum requirements of the engine, receives fuel under vacuum from the
fuel tank containing entrained air/vapor, particulate contaminates and
unknown quantities of water. The fuel passes through the water separator
which removes the large particulate contaminates that could damage or
jam The gerotor fuel pump. The fuel, with only entrained air/vapor and
tiny particulate contaminates remaining enters the fuel pump.
The
fuel, under positive pressure flow, enters the fuel filter. As the fuel
passes through the filter media and the remaining particulate
contaminates are caught and contained, the entrained air/vapor is also
separated. Through the POSITIVE FUEL AIR SEPARATION FEATURES of the
PATENTED FUEL PREPORATOR the separated air/vapor is discharged from the
filter and back to the fuel tank through the Primary Air/Vapor
Discharge Port.
The
fuel passing through the filter media, free of contaminates & power
robbing air/vapor and at pressures and flows always able to meet the
needs of the engine, exits the fuel filter through two passageways.
First, the fuel for the engine, passes into the fuel pickup tube and on
to the engine. Then. the excess fuel not needed by the engine recycles
internally through the pressure regulator back to the water separator.
