Some moisture is common.
The less vacuum leaks you have the less moisture you get in my experience.

MrCab I see water vapor(moisture)on 1st crank after setting from one week to the next also.
I try and put the hose for my vacuum gauge on one side and pull vacuum and the pop off valve on the other side.If I mount the vacuum pump on the drivers side I like to pull vacuum from the passenger side,I do not think it really matters but find it's best that way to help keep it from spraying a fine mist of oil out the top of the filter when its at max pressure.
PS If I run one off another Big Block Mopar engine with the valley plate like Indy,I will pull vacuum from it as close to the center as I can get.

You get moisture all the time BUT you just pump it out due to the engine being warm.... the air going into the engine is carrying the moisture in

When you drain your vacuum tank you will also find a small amount of water the 1st time and this is normal.On an alcohol engine you will find even more water. PS there is no need to worry about forgetting to drain your tank.If you do it will remind you when it needs draining! I have the Wife save the small butter bowls to drain mine in.I like to leave my pit space as clean as it is when I get there.At the end of the day you can put the lid back on it and duct tape it and put it in the trash can.Some may say not to put it in there but I say thats better than draining it on the ground.

Sure.. alky engines(fuel) absorbs water so when its heated it separates... same with E-85.. so you have 2 sources of moisture being carried into the engine
