Very solid construction, made it really easy to hook up a pressure guage. I also think this could be adapted to prime engines with a pressurized oil source.

The pipe plug on the side port was too sloppy for the set screw plug and doesnt seal. I had to wrap with a lot of teflon tape to get any kind of seal. Other than that it worked fine. I will have to drill and tap it to a larger size to do it properly.

Got this to check the pressure on my 06 6.0 vortec, just swallows the threads and does not even try and thread on, had to put teflon on the side port and there was metal shavings down in the threads as soon as I pulled it out of the box.

I installed this on a 3.6 gm engine and started it and I didn't notice the plug on the side was leaking and ran all the oil out of the engine. Opps I caught it before the engine blew I then removed the plug and glued it in. I have yet to try it I'm waiting on the glue to dry....
