Aurora S. ★★★★★ Oct 22, 2026

The install kit made swapping out my old pump on the G35 surprisingly straightforward, and the car now pulls hard without any fuel starvation, even during autocross. It's definitely overkill for a mostly stock setup, but I'm future-proofed now.

Finally got around to installing this on my Legacy GT, and the included install kit made all the difference—no hunting for extra parts. The pump itself feels solid, and I’ve noticed the car pulls harder through the mid-range now.

Was a direct bolt-in for my 350Z, didn't need any modifications to the hanger at all. The included install kit saved me from having to track down separate connectors. Idle is quiet and it handles full boost without any fuel pressure drop.
