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!
The compact AirDog®
provides the most effective technology designed specifically for diesel
pickups to remove water, particulates, vapor and entrained air from
diesel fuel. The AirDog® replaces the Cummins factory lift pump
and filter system, and enhances the fuel delivery to the Powerstroke
and Duramax with a commercial duty system.
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 from 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
physics behind AirDog® technology:
Diesel
fuel contains varying degrees of entrained air in the form of foam
on the surface or suspended in the bulk fluid as tiny bubbles. Additionally,
fuel is driven into the fuel pump by atmospheric pressure, which is
usually only enough pressure flow to fill the pump at idle speeds.
Consequently, at higher operating RPM’s, the stock pump cavitates
producing vapor.
Air and vapor
are compressible. The presence of air/vapor in the fuel injector
delays the pressure build-up. This delays the injection, resulting
in Retarded Injection Timing.
Retarded injection
timing in a diesel, just like bad spark plugs in a gasoline engine,
causes lost power, poor fuel mileage, and an increase in exhaust
emissions. Retarded Injection Timing caused by air/vapor is the
primary source of the rough idle, lost power, increased fuel consumption
and excessive exhaust emissions of the diesel engine.
Air/vapor in
the injector can also cause permanent damage in the form of galling
and pitting of the barrel/plunger assembly and tip erosion.
The conventional
vacuum feed fuel supply system does nothing to remove entrained
air from the fuel. In fact, it only makes things worse. As
the filter plugs with use, the already inadequate fuel flow
to the engine is further reduced, increasing cavitation and
retarding injection timing even more.

Small
& Compact: Only 7"L X 10"T X 3.2"W
Single
Piece Pump Body: Replaces the old 3 piece pump design
reducing the number of parts, unit size, and weight. This results
in a sleek, low profile pump assembly and eliminates the need
for leaky, messy gaskets!
AirDog™
replacement components for the Model FP100 AirDog fuel system. The
Fuel Filters are 2 Micron, and typical service interval is 1 year,
or 15,000 miles. Water Separators have a much longer service interval
and replacement depends on the physical condition.
