Bought this a while back just used it yesterday to check fuel pressure. Worked great and showed me.what I needed to know.However, I could not leave it installed as it leaked fuel out the Schrader valve portion as soon as it pressurized. So it works to test with a gauge on it but I had to remove it and reinstall the plug to stop the leak. Kind of a let down.

This valve is of good quality. It doesn’t leak if left installed like some of the more expensive ones I’ve tried.

Worked for what I needed and got here on time. The threads weren't as tight as the plug that is removed to install adapter, but I didn't notice leaks. I wish it was a 45° angle or shorter so it didn't conflict with the coolant hose.

Affordable and great way to test 6.0 fuel pressure. Do not leave it installed. The valve will leak and kill your injectors. Don't forget to lube the o ring before installation.
