Does the job
Fuel pressure is stable, installed sensor right into the snubber. 24 inches from the injection pump on my 24 valve. It is functioning without issue but there was a warning to install further away from the pump. 1 week of use.

It works
2001 Dodge 2500 Cummins. Easy install. It goes between the fuel line T & the fuel pressure gauge to prevent killing your gauge. My gauge doesn’t bounce around so it is working.

Works as it should.
Snubber valve works well. The issue is the electronic sensor.

Used for a boost gauge
Was experiencing significant needle flutter/bouncing above 15 psi on an AutoMeter boost gauge for my 6.7 Cummins. Used this to modulate the boost line, gauge now works as intended and smooth up to 30 psi

Excellent quality
My after-market fuel pressure guage has no fluctuations and it's lasted over a year now!

A must have 👍
This snubber prevents spiking of the fuel pressure gauge needle which allows accurate measurement of fuel delivery.A nice addition to have in your supply line.A+++++++

Poor quality , and expensive.
Not a quality made product , for the price i expected more , i had a hard time stopping diesel fuel leaks between the snubber and the fuel pressure sensor, used teflon tape , then thread sealing compound, i was prudent when tightening not wishing to strip the threads or shearing it off , i had no confidence with the integrity of this item.

Did not work on Glow shift fuel pressure on Cummins P7100 pump.
Did not work on a digital Glow shift fuel pressure gauge on Cummins P7100 pump. I used a flow valve instead to limit fuel flow to Glow shift sensor, then everything worked properly. Now have another useless thing in my toolbox junk drawer.
