Connects a 3/8" female quick-connect to -8 AN JIC male.
The Racetronix QDA-38F8 takes a 3/8" male quick-connect tube end, such as the end of a factory fuel line, fuel rail inlet or pump module outlet. The other end is a -8 AN JIC male. It is machined from 6061-T6 aluminum and black anodized.
Key features
- 3/8" female quick-connect.
- -8 AN JIC male.
- Quick-release clip, no tools needed.
- Viton O-rings in the female quick-connect.
- Black anodized 6061-T6 aluminum, E85 compatible.
- For fuel systems, e-vac systems and vacuum or boost lines.
How to connect
- Check the male tube end is clean and undamaged, with no burrs on the bead.
- Push the male tube end straight into the adapter until the quick-release clip catches it.
- Pull back on the line to confirm it is locked.
- To release, press the clip and pull the line out. No tools are needed.
Connect the AN end to an AN female hose end or fitting of the same size. AN (37° flare) fittings seal on the flare: do not use thread sealant or tape.
Choosing the size
Quick-connect sizes go by the outside diameter of the male tube end. Measure the tube just behind the raised bead: 1/4" is about 6.4 mm, 5/16" about 7.9 mm (often called 8 mm), 3/8" about 9.5 mm (often called 10 mm) and 1/2" 12.7 mm. A female quick-connect only fits the male size it is made for.
Match the quick-connect size to the line or component you are connecting, then choose the other end to suit your hose or fitting.
