You need a new round one, and you will need to bend the pipes a bit to fit it. If you are fiddling with the old rectangular ones, they all leak by now and should be tossed.  Any RV store should sell them, or you can get one here: http://www.gowesty.com/ec_view_details.php?id=2448&category_id=&category_parent_id=

Hi to all,

I have tried three of them and all leak at that little hole.  I have installed them in all direction, but did not help.  
Did I miss anything?
The other kind I can buy is about two inches longer and I would have to cut the copper pipes to fit.  I’m not even sure, I can fit it next to the tank the way it supposed to be installed.  
Who knows of this?
Thanks to any input.
Zoltan
