AirDog® FPII-200 4G Cummins ISX & Signature 600


SKU: A3SPBT452 Category:


The Pre-Combustion Solution for Maximum Engine Efficiency! The AirDog® FPII 4G Fuel Air Separation System is the state of the art fuel processor that removes not only water and particulate contaminates from the fuel flow to the engine, but most importantly, it also removes the entrained air and vapor. Additionally, the AirDog® maintains the necessary net positive pressure head to the engine fuel pump to prevent cavitation and the formation of vapor. The dual port design feeds the gerotor from both sides, which hydraulically balances the outer gear. These special features guarantee not only the quietest pump, but also the most durable pump available. The fuel filter monitor, with a dash mounted indicator light, lets you know when to change the filter without waste of filter life or fuel economy. No more guessing! The stainless steel adjustable pressure regulator is part of the demand flow system that recycles the fuel not needed by the engine back to the water separator and through the filter for continuous multi-pass filtration. The patented AirDog® is the only fuel air separation system with third party verified positive air separation. The newly redesigned and patented air bleed port vents the separated air and vapor from the fuel with a barely measurable pressure drop or loss of flow. The AirDog® air and vapor return line connects to the engine return line with engine specific fittings that make installation quick, easy, and least expensive.

This kit includes (1) AirDog® FPII 4G System, (1) FF200-MG-6 Filter, (1) WS200-WS, (1) 5E-2-010 Wiring Harness, 7ft of DOT Air/Vapor Return Line, and (1) Engine Specific Fitting Kit (all fittings needed in most cases).

Bracket Option: Sandwich Bracket Kit $95 (Part # SBK-1000). This kit includes (3) sandwich mounting plates and all needed hardware. The sandwich bracket slides right over the existing frame with no drilling required.

The AirDog® FPII 4G uses the AirDog® FF200-MG-6 or equivalent fuel filter and WS200-WS or equivalent water separator. Call for questions on cross references. For maximum performance, use of the PureFlow WS200-WS and FF200-MG-6 are recommended as the filters were designed for use with the AirDog system.
