Miles T. ★★★★★

I was worried about fitment, but this pump dropped right into my RX-8's tank without any modifications. The included install kit saved me from hunting down o-rings and connectors. Car fired up instantly and idles smoother now.

Scarlett R. ★★★★★

The install kit made this a direct swap for my RX-8, and I’ve had zero issues with fuel pressure since. It’s been running reliably for a few thousand miles now, which is exactly what I needed.

Kevin Y. ★★★★★

Dropped this in my RX-8 and it fired right up without any priming issues. The included install kit made the swap straightforward, and the pump itself runs quieter than I expected for a high-flow unit.
