89-93 Dodge 5.9L Cummins Diesel 100GPH Airdog 2 4G Fuel Filter/Pump System

The new AirDog® II 4G Demand Flow Fuel Preporator®

89-93 Dodge 5.9L Cummins Diesel 100GPH Airdog 2 System with preset fuel pressure regulator.

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 a preset fuel 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.
