Thomas N. ★★★★★ Oct 22, 2026

Snapped right onto my fuel rail and the 6AN flare side seated perfectly with no leaks on the first try. The quick connect clicks in solidly, way better than wrestling with hose clamps.

Lily M. ★★★★★ Oct 21, 2026

The anodized titanium finish on this fitting looks sharp and resisted scratches during my install. Snaps right into the 5/16 quick connect with a solid click, no leaks on first try. Clean adapter for converting a 6AN line to factory style.

Swapped out a bulky adapter on my fuel rail and this fitting threaded on smooth as butter. The anodized titanium finish looks great and seems like it'll hold up way better than the old raw aluminum piece.
