Frequently Asked Questions
How do I confirm the thread and line size for the Fuel Pressure Boost Compensation Kit?
Match the exact AN, ORB, NPT, or OEM specification on both mating components. Similar nominal sizes can use different threads and sealing surfaces.
Does this fitting require thread sealant or an O-ring?
Use the sealing method specified for the thread type. Flare, ORB, and tapered pipe threads seal differently; incorrect sealant can contaminate the fuel system.
Can this fitting be used with E85 or methanol?
Compatibility depends on the fitting material and every seal or O-ring. Confirm AirDog's specification for this exact part number.
What torque should be used?
Use AirDog's value for the exact material and thread. Over-tightening can distort flares, cut O-rings, crack housings, or damage threads.
Installation Instructions
- Confirm AirDog part number AD-BOOSTCOMP, the complete system design, fuel or fluid type, and all required supporting components.
- Relieve system pressure, disconnect electrical power, work in a ventilated area, and eliminate ignition sources before opening any fuel connection.
- Install with the exact port sizes, seals, mounting orientation, line support, filtration, wiring, and torque values in AirDog's current instructions.
- Prime and pressure-test the complete system; inspect every joint, seal, vent, and electrical connection for leaks, heat, abrasion, and voltage drop.
- Verify stable pressure and safe operation under load, then recheck fittings and mounting after the initial heat cycles.
