Quality product.

Works perfectly
Used in my military generator, which is 24 volt, so I used the dropping resistor, and it works great.

Great quality
I installed this in my UTV because of the dummy lights come on it's to late

Should have done this sooner.
This was a perfect replacement for my boat oil pressure gauges on my upper helm that were very old and one of which did not work. Now I have a functional matched pair at a very fair price.

False advertising
Hole in the world can you call this a kit. My opinion is a kit would include everything you need. There is no sending unit. False advertisement misrepresentation.

Guage has proper 3/16"( #10) studs on the back that are correct size for the factory ring terminal connections on my 1980 Thundercraft.

I would have given 5 stars but the listing was labeled as a kit, this was the gauge only. Regardless, it went in easy, works great, hopefully keeps water out from our Atv. I'll update down the road.
