SYSTEM OVERVIEW
Welcome to the
AirDog
®
Heavy Duty Industrial
Fuel Air Separation System for Class 8 Trucks
The AirDog
®
, with ADVANCED FUEL AIR SEPARATION, DEMAND FLOW, ADJUSTABLE
REGULATOR, LOW PRESSURE SENSOR with LED INDICATOR and the 4G-HD FUEL
PUMP, is a premium fuel filtration and delivery system for the Detroit Diesel Series 60
®
engine,
model years 2003 thru 2009.
S
pecifically, if the fuel pressure/flow to the injector, even with entrained air and vapor
removed, is insufficient to totally fill the injector barrel on the up stroke of the plunger, a void
or low pressure will form that allows vapor to re-form within the injector. The result, “injector
lag”, is just another name for “delayed injection timing”. No matter what term is used, it leaves
the engine with increased fuel consumption, lost power, and increased exhaust emissions.
The Detroit Diesel Series 60
®
engine, model years 2003 thru 2009, utilizes “FOR-SEAL” fittings
with steel lines on the high pressure side of the transfer pump. These fittings have small passageways
and are restrictive to the fuel flow to the engine. To maximize the efficiency of the 2003 THRU 2009
Series 60
®
engine, it is necessary to replace the restrictive fuel fittings and lines with the larger and
less restrictive lines & fittings.
The
“UPGRADE” kit is NOT included
with the Detroit installation kit, although the complete
and detailed instructions are included.
