Trim pump vent screw -- anyone know the thread pitch?

[jmorgan87]

So my ram's do not hold pressure when up, can be pushed down. A friend noticed the vent screw is missing. We don't know if this could be the sole culprit, but a good place to start.

Anyone know the thread pitch for this screw? I looked through the manual, but found nothing. I was hoping a local parts store might have something I could use, but having a thread pitch be invaluable..

The vent is to vent the fluid in the reservoir. It does not affect the rams.

My 2 trim pumps have what look like sheet metal screws in the vent hole.
Not sure if that's what supposed to be there - but they work fine.
