Amelia ★★★★★ Oct 22, 2026

My RX-8 was running lean at high RPMs, and this pump's 340lph flow rate completely solved the issue. The install kit made it a straightforward afternoon job, no guesswork needed.

Steven R. ★★★★★ Oct 21, 2026

The install kit made swapping out the old pump surprisingly straightforward, and the 340lph flow rate has my pressure gauge rock steady even during hard pulls. My RX-8 feels like it’s breathing easy again on the highway.

Emily L. ★★★★★ Oct 20, 2026

Installed this in my RX-8 over the weekend and the 340lph flow rate paired with the included install kit made the swap surprisingly straightforward. The car fires right up and idles steady, no more fuel pressure drops when I push it hard.
