- What does 6 AN ORB mean?
- It is a 6 AN (about 3/8 in) port thread with an O-ring boss seat, common on fuel rails, regulators and filters. The O-ring seals against a machined boss face, not on the threads.
- What hose fits the push-on side?
- The 0.31 in figure is 8 mm, so it takes 8 mm or 5/16 in push-on hose. Clamp it, since a barb alone can pull off under fuel pressure.
- Is it for fuel injection only?
- It is sold for EFI fuel systems. It is not rated for brake lines or high-pressure hydraulic use, and no pressure rating is given.
- What is in the box?
- The adapter alone. No O-ring, hose clamp or retaining clip is listed, so plan to source those separately.
- Will it fit my fuel rail?
- Only if your rail has a 6 AN ORB port. Measure the port and hose first, because a wrong thread will not seal.
