Honda Fuel Feed or Return AN Hardline Adapter
Our Honda Hardline adapter fittings come in two different sizes - Feed and Return. These are the exact sizes your need to convert your 90-00's Civic Integra Del Sol etc Fuel Hardlines into 6an for the feed or 4an for the return side.
We also offer an adapter fitting to convert that 4AN on the return side to 6AN if needed.
These are the same fittings we use in all of our fuel line tuck kits. If you need replacements for looking to make your own kit.

Fit perfect. No issues.
Needed an adapter to connect my 6an fuel return line to the barbed hardline. Adapter worked great once I tightened it up, didn't leak any fuel. If you are using this for the barbed hardline you need to cut off the nipple at the end so that the ferrule has a clean flat surface to mount to. After sliding the recieving fitting over the hardline, put the ferrule in place and attach the rest of the adapter. Tighten it up until it stops leaking fuel.
