This -6AN adapter fitting is built for AN fuel and fluid plumbing where connection sizes need to match the hose, tube, rail, or threaded port — specifically converting to a 3/8" factory-style female quick-disconnect fuel tube connection. The design supports secure, serviceable routing for fuel lines, EFI conversions, return systems, and performance engine bay plumbing.

Use it when building or servicing custom hose assemblies, quick-disconnect fuel tube connections, push-on hose ends, NPT adapters, swivel couplers, or crossover fittings. Confirm tube or hose diameter, thread type, flare or sealing style, and fluid compatibility before installation.
