Frequently Asked Questions
How do I confirm the connection sizes for the 8AN High Flow One Way Check Valve - 350 GPH?
Identify the thread standard, nominal size, flare or seat, and sealing method on both mating components. AN flare, ORB, NPT, SAE, and metric connections are not interchangeable.
Does this connection require sealant or an O-ring?
Use only the sealing method specified for the exact interface. Flare, O-ring boss, and tapered pipe threads seal differently.
Is this component compatible with E85 or methanol?
Confirm the material and every seal or O-ring against the exact fuel blend, pressure, temperature, and service conditions.
Installation Instructions
Relieve fuel pressure and disconnect vehicle power before service. Work in a ventilated area away from ignition sources. Follow Fuelab's current instructions for the exact part number, use compatible lines, fittings, seals, wiring, filters, regulator, mounting hardware, and torque values, then prime and leak-test the complete system before starting the engine.
