FX Gladiator Help Please!

I had the screw that screws into the action and has female threading on the top break off. I went to look at diagrams of the Gladiator and all the ones I found have a different type of brass tune to connect the two air tanks than mine does. They all show a tube that goes from the front of the action where the tank screws in to the back behind the hammer spring. Mine goes to the same place by the hammer spring but terminates beneath the screw that I mentioned above that the stock screw goes in. Does anyone know anything about this?
 
Thanks Dreuf I had seen that but was hesitant as I wasn't sure why the diagram isn't categorized under the Glad Mk2. I have to order the part, do you think I should order the longer one, in other words aside from the components in that diagram if I want to do the reg in the future is that all I have to get aside from part F? I would like to just put the longer pipe in. (That's what she said) Any suggestions on where to order from? Last time I used Bagnall.
 
Unfortunately FX did not release the Glad mk2 drawings (not so dramatic since it is a royale base block and the vermi mk2 is the same)

If you plan to add a reg in the future you will need parts C1 + F9/10/11/12/13. Of course you will need the reg (ref A36).

The reg will give you a massive number of regulated shots (120 at 60J for me).

I live in France so not a big help for you. In the US I think AOA could be the way to go.
