Riley ★★★★★ Oct 21, 2026

Perfect fit for my return line setup—threaded into the fuel rail without any leaks and the barb held the 5/16 hose snug. The anodized finish seems durable enough for underhood use.

Stella V. ★★★★★ Oct 19, 2026

Used this to plumb my fuel pressure regulator, and the 5/16 barb holds the hose tight with no leaks. Threaded right into the NPT port without any fuss.

Robert X. ★★★★☆ Oct 22, 2026

The matte black anodized finish looks great and seems durable, though I wish the threads were just a tad smoother tightening down. It connected my 1/8 NPT port to a 5/16 hose without any leaks. Good quality for the price.
