Help building a model of a 100 ton hopper properly

[railbuilderdave]

I hope I’ve posted this in the correct location.  I wanted to know if I was building the this model properly before I grabbed the glue.  I’m not sure what direction the part in the photo that are circled need to be facing.  I haven’t been able to find any photos and the other model I currently have are different enough that they didn’t help me in this battle as well.  I think the cylinder in the back is correct but it may be facing the wrong direction as well.  I thank you for any and all help.

I know, I know, not hoppers.

I would say you have it correct.  There is no doubt about the reservoir.

You can make out the cylider here which should be in line with the chain from the brake wheel rod:

And you can see the valve here if you can turn your computer screen sideways:

Thanks guys, that's a great help.  I think I have enough details with this I can detail the lines as well.
Jason - I was lucky tonight as I checked here using my wifes laptop and was able to turn the monitor sideways.  ;D
