Harper ★★★★★ Oct 22, 2026

Mated this to my fuel rail and the quick connect snapped on with a satisfying click, no leaks after a week of daily driving. The anodized matte black finish blends right into the rest of my engine bay, and the threads were clean with no burrs.

Finally got my fuel line hooked up without swearing at the car for once, the matte black anodized finish looks clean too. That 5/16 quick connect side snaps right on and holds tight, no leaks after a week of daily driving.

This adapter made connecting my aftermarket fuel rail to the factory line a breeze, and the matte black anodized finish looks clean and professional under the hood.
