Thank you gentlemen I found some docs on VDH that dispay a tool that is used to unscrew the valves i will need to make one. My good friend is a plumber i will ask him to help with the rest of the tools
 
Elan,

Be sure to post the results.

I will It will take time though. My friend has confirmed that they have a huge vise in in the shop so i now need to make the tool. I will not hydro them i think will just inspect them and transfill. Do not want to place a stamp on the tank :)
 
Concerning the tool, I have used a very large (15 inch) crescent wrench on mine. I needed to take the overpressure relief valves off in order to use it though. I then put cardboard on each side of the valve to keep from scaring the valve's finish. Looking at your, I think they may be different than newer twin tank manifolds, as it seems to have only one overpressure relief valve. Also, it is probably the old type with the lead insert that is pushed out in an overpressure situation. That should not matter (having only one), as it is all in the same system, pressure-wise. The overpressure relief valve will need to be replaced with the modern one (copper disk) in order to get you system working.

Thanks a lot John, I will keep that in mind.
 
I use thick Teflon tape for tapered valves these days
the stuff used in gas (the smelly stuff you cant see )
applications.

Not the cheap see through white stuff.
