Universal Fuel Pressure Gauge

Great gauge quality and durability is strong. Installed on the back of my fuel rail to be able to see the pressure and confirm 43 psi. Looks great, and it perfectly accurate. Readability is easy as it is screwed on and you should be able to face it in the direction needed. This was a great value for the money.

Used on a 99 7.3 that has zero ways of knowing fuel pressure even with a obd2 gauge.

This universal liquid-filled fuel pressure gauge was exactly what I needed for tuning my fuel system. It reads clearly up to 100 PSI, and the liquid-filled design really helps dampen needle vibrations for more stable readings. I installed it on the fuel rail with no leaks or issues. So far, it's holding up well and gives me peace of mind while making adjustments. Great value for a budget-friendly gauge

This looks and works exactly like the one I bought for another car, it cost 10 × more. I will buy them from Amazon from now on.

after installing the pressure gauge it never moved the needle and it leaked fuel from the end fittings. tried to tighten them and it still leaked. i removed the fuel pressure gauge and noticed the liquid inside the gauge leaking. had to remove it from the fuel rail to prevent a fire.

The threaded port where the gage screws in is machined a little off to one side but dosent matter much. Gage seems ok but if used in horizontal position with face up the oil in gage isn’t all the way full so it looks bad. You can see the bubble of air in the listing photo. Don’t think I would buy again

Used it to help figure out what fuel pressure I needed the regulator set too.

Used this gauge and fitting inline on my fuel system for an added area to see fuel pressure when not looking at dash gauge. Easily installed and works well.
