Swapping out a bulky adapter for this one freed up serious space near the firewall. The matte black anodized finish blends in perfectly and the quick-connect clicked on with a satisfying snap.

Finally got my fuel line set up properly with this adapter—the ORB thread seals perfectly against the rail without any leaks. Snaps onto the 5/16 quick connect with a satisfying click that gives me peace of mind.

Finally, an adapter that actually fits my fuel rail without needing a thread chaser. The o-ring seats perfectly and the quick connect clicks on solidly, no leaks at all. This solved my fuel line swap in about ten minutes.
