Came well packaged and secure as any precision instrument should be.Price was Middle of the road compared to other gauges.So far the unit functions perfectly in my FI fuel supply line. Happy with the product ðŸ‘ðŸ‘.The attached photo is current, 06/05/23. The vehicle has sat for 3+ days and the gauge is still holding pressure. That's really impressive. Purchase with confidence ✨ï¸.Cheers ðŸ», G.

Nice shiny gauge. Hopefully it is accurate. Surprised to find my fuel pressure running at 30 expected it to be higher. looks great, hasn't leaked yet.

I purchased a different brand at first and it only lasted a couple of weeks because the rubber plug fell off. Causing the glycerin to leak out. This one has lasted longer and was a better value.

Gave it 4 stars across the board because it's the first one I ever bought. Nothing to compare it to.Know ahead of time how high your fuel pressure is supposed to be. Mine is on the low side.

Gauge looked like it was good quality out of the box. It initially read correctly but over the last month I have noticed the pressure is slowly creeping high on the gauge. I have changed regulators to check and the pressure stays high and inaccurate. Nice looking gauge but does not appear to be able to handle +50 psi.

I have no way to check for accuracy. However, the pressure reads where the regulator is rated. No issues. I don't know that I believe this is made in the USA. I think the labeling referencing the US on the meter just states where the Marshall office is located.
