Do your Autometer mech. oil press. guages make noise?

I got the Ford Racing (made by Autometer) mechanical oil pressure guage for christmas, as well as the water temp guage. They look sweet.

But when I installed it, I had the copper line resting on the valve cover and the small amount of rocker noise I have was resonating through the line into the guage and I could hear it inside the car. Well today I moved the line away from the valve cover and it took the noise from the rockers away but it still has a slight noise. It kinda sounds like a slight hiss.

It's not too bad, and I've gotten used to it, but if no one else's does this then it's probably my particular guage and I need to exchange it for a new one.

Just checkin if anyone else's does this,
Thanks everyone
