I lost a line fitting from tank

[ShaneCl]

I had to rebuild the drive pumps so I am in the process of getting my machine put back togather. There are three lines I am a little lost on and can not rember where thy go. I can only find five fittings do I have one line I do not know where to connece. I have two fittings on the bottom of my tak. I has a filter and goes to the Bics valve. The is another small line I I am not sure if it is correc but goest fome the fitting on the side of the pump aoutlet and goes to the lift valve above which almost make a loop. The last small line comes from the bottom of the tand and I can not find a fitting anywhere. I have no clue where this joke can go. It is a short small line and is limited where it can reach but the is no empty spot fo it to go . Please help.

First off, what machine?
It should be a case drain return line. There is one that goes from the left drive motor (left as you are sitting in the seat) usually and one from the lift arm pressure release and one large one to the main hydraulic pump. I can't remember if the fitting from the drive pump is on the front or back, there is a case drain line that connects to it though.
