Vans Manifold Pressure Gauge

Installed a Vans Manifold about a month ago, worked great until this past weekend, now pegs full rotation. Checked the wires and connections, everything seems fine. Has this happened to anyone else?

yup

I got about 50 hrs out of my Van's MP system.

Happened to me today...

The same thing happened to me today in the middle of my flight. It was working fine one moment and then a looked little while later and it was pegged full deflection.

I've only got 21 hours on the gauge.

I have a fixed pitch prop, but have still really liked having the manifold pressure gauge.

I noticed a little moisture in the small transparent line.

Today was the first time I've climbed higher than 4000 ft. And it happened somewhere between 4000 and 10000 ft.
