🔍 Marshall Instruments LS00100: Silver Dial Fuel Pressure Gauge - Accurate & Reliable Monitoring for Optimal Engine Performance Review

I bought another brand first and it only lasted a couple of weeks because the rubber stopper fell off. Causes glycerin leakage. This lasted longer and was cheaper.

I have no way of verifying accuracy. However, the pressure is read where the rating of the regulator is. No questions. I don't know, I think it's made in the USA. I think the markings related to the US on the meter simply indicate where the Marshall office is.

After I received the gauge I installed it on my truck. Worked great for 2 weeks but today I rebuilt the fuel pressure regulator on my F250 6.0L diesel and found all the liquid (oil) had come out of the gauge and the needle also stopped working. Not a worthy product to last long.

I needed a hand gauge to check if there was a problem with my electrical gauge or if the combustion pressure was coming through the injector pin in my F250. This gauge is beautiful, easy to read, and easy to wire up. The problem was the wire connection to the back of my electric pressure gauge.

# Update installed, works great, fast delivery! It remains to install. I'll edit the function later. 4 stars at the moment because the image has a white background and the result is all silver. I'm not sure if the product description is correct or what. Looking more closely at this and the previous review I think this is correct. Even if it looks white in the photos.
