Was looking at the possibility of mounting two 6 cuft ponies on the front side of my back plate. My thought was one would have a din valve and a hose with the din male fitting going into the valve. And the other end with another din male fitting going into a H- valve on the other ponie and other reg hooked to that din valve. Before you get mean I want to do this for#1 balance #2 for travel #3 because of the different ways boats hold their tanks. This setup would not be affected on the back side of the bc. But does anyone make a hp flexable hose with a male din fitting on both ends? I will lose 1 cuft by not using my 13 cuft ponie and I can live with that. Thanks It's just a thought for now!
