PureFlow AirDog/AirDog Pressure Port Hose Splice

AirDog builds the most recognized Fuel Air Separation Systems in the diesel performance industry, hand-assembling every unit to ensure consistent quality for owners of Cummins, Duramax, and Powerstroke-powered trucks. The AirDog system separates entrained air and vapor from diesel fuel before it reaches the injection pump, protecting expensive fuel system components and delivering more consistent fuel pressure for better performance under load.Popular UpgradesThe AirDog II-5G is the flagship system, featuring an integrated diaphragm fuel pressure regulator for finer pressure adjustability and improved flow at the pump. With larger porting to reduce cavitation and improved 12-gauge wiring harnesses with weather-sealed connectors, the II-5G is the choice for owners who want the latest generation technology. The system retains AirDog's proven Demand Flow operation, recirculating unused fuel back through the filter base for clean, vapor-free delivery to the injectors.Why do diesel truck...

Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...

Automotive fluid system fittings are the hardware that connects hoses, hard lines, and components within fuel, oil, cooling, brake, power steering, and intercooler circuits, and the quality and correct sizing of these fittings directly determines whether a high-performance fluid system remains leak-free under the pressure, temperature, and vibration conditions that race and street performance environments produce. The AN fitting standard, derived from military Aircraft-Navy specifications, provides a consistent thread and flare geometry across fuel, oil, and hydraulic applications that allows interchangeability between brands and simplifies system design by providing a known thread engagement and sealing approach for every connection. Swivel fittings, bulkhead adapters, 45-degree and 90-degree elbow fittings, tee and union adapters, and reducer fittings allow performance builders to route lines through tight spaces and around obstacles while maintaining correct flow area without res...
