M-Series Vent Trap

I installed a stereo and needed something to prevent the probable water from destroying it from the vent left open. So I decided to add a trap to allow the air to come in and trap the water. There is a bit more resistance to the air coming in but I think that is a good trade off to a destroyed stereo.

I installed the stereo in the center, set back a bit. I plan to put super magnets on the cover if I need to hide the stereo.

So I made a crude trap out of cardboard for test fitting.

After all the fitting and testing, I then made another trap using thin cardboard for a sheet metal pattern.

To seal the thumb tip to the vent actuator arm, I'm epoxying a copper pipe section onto it.

Thumb installed.

Drain outlet installed. I used aluminum pop rivets throughout.

Installing the trap using ty-wraps to attach the thumb tip to the actuator arm. Note the inside of the trap is coated with Hirsch's gas tank sealer for S & G's.
