Marshall Instruments MSB00100 Liquid Filled Fuel/Oil Pressure Gauge Black: Accurate Monitoring for Efficient Performance Review

Works great. Read and install East. And a much better price. Bought another brand for twice the price and it leaked like crazy.

Exactly what I was looking for, black! Filled with liquid (thick clear) and appears solid, of good quality. I hope it is made in the USA as advertised. (If this were my product, I would remove the "Made in Taiwan" (or Hong Kong) sticker from the bubble wrap. (Shows food for thought.)

I've just finished fitting my Buell XB9R engine/bike for the Bonneville run so it won't get any real testing until next season. Great looking gauge! The front says Anaheim, California, but I was a little disappointed when I opened the box and found a "Made in Taiwan" sticker on the bubble wrap (as another reviewer noted). I won't throw you under the bus because I went back and reread your specs and couldn't find where it says that this particular sensor was made in the USA. I hope it holds up…

This is a nice convenience item if you have a performance oriented engine or even just want to keep an eye on oil pressure. If you always have a mechanical pressure gauge that is designed for continuous use, you do not have to undertake a pressure test. I haven't had any issues with it so far, but I've seen a few other cases where oil has gotten into the sensor or some other problem has arisen. I can only speak for myself and pushed the car away from time to time, otherwise it's my day-to-day…
