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.

Fits and works just lile the orignal gm tool. Great for checking oil pressure without making a mess

Go ahead and set your 35 bucks on fire and then go by the otc unit, save yourself some time.

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.

Worked good, the side port's threads are not tapered so you cannot use a pipe plug to seal it. So it leaked a bit when in use.

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....
