George ★★★★★ Oct 22, 2026

The 3/8in NPT threads fit perfectly on my rail, and I noticed a much steadier pressure reading on the gauge right after installation. For the price, it’s a solid little piece for cleaning up fuel delivery.

Stella ★★★★★ Oct 21, 2026

This thing took maybe ten minutes to install with basic tools, and the difference in fuel pressure stability is very noticeable. The 3/8in NPT threads threaded in perfectly without any leaks.

Was a little skeptical at first, but after installing this damper my fuel pressure gauge readings finally stopped bouncing around at idle. It's a simple part that does exactly what it's supposed to.
