Fuel Pulsation Damper -3/8in NPT

My pressure gauge needle stopped bouncing around after installing this damper. The 3/8in NPT fittings matched my existing lines perfectly without any adapters. Feels solid and does exactly what it's supposed to do for consistent readings.

Finally got my fuel pressure readings to stop bouncing around at idle—this damper smoothed everything out instantly. Install was straightforward with the 3/8in NPT threads.

After chasing erratic fuel pressure readings for weeks, this damper finally smoothed things out with its 3/8in NPT fittings threading in cleanly. The gauge now sits steady even under hard throttle, which is exactly what I needed for my high-flow setup.
