dhbiker1, last item on p.480..yes..horizontal installation only. Get npt and clear so you can see if anything gets caught under the flap such as a chip of sawdust. Last item on p.477 will work as well and is directional..npt as well.
The reason you would get all the frothing is because if you hook your sap flow to the top inlet...that IS the wash set up and it is made to be turbulant. Your going to have the same amount of vacuum on the top and the bottom..the port holes in the rod don't magically get bigger! Like I said..mount your jar at the height of your mainline and feed into the bottom. Trust me, you will not have a problem. Also, your not going to have a solid flow of sap at all times..these units were part of a dumping station and had full flow of milk once the dumping station was filled. There was a delrin ball at the bottom of the dumping station tub that prevented air to enter the system. That is why you have to have a leak free set up as well as the proper flow check valves. Note, if you have your mainline set up on the bottom and at the same level, your sap will flow through when the vac is not on or will thaw with the rest of your mainline.
Just went and saw your new picture...you forgot one VERY important last thing to fix. You should have a total of 3 ss hairpin clips. Place one on top of the weight, one under the weight and the last goes almost to the bottom of the rod. The float ball must NOT sit flush with the bottom of the float. I think the slot for the pin is maybe 4" up the rod. It will work better. As you have it now the fluid is not being allowed up the jar because of the weight on the jar. The weight acts as resistance for when it shuts the vac off. Just a five minute fix!
