Next job on my agenda was to reclaim some cupboard space back in the van. Even before we bought our van this cupboard annoyed me. I removed both 1" pipes that are for filling tante tanks and the breathers as well as the mains pressure supply pipe.
With the pipes removed I relocated the mains feed to behind the mudflap so will never have to muck around with that little door again. I put a one way valve just on the other side of that chassis rail before the pressure regulator and teed into the main water line.
Wanting a better way to fill the tanks I came up with this solution which I teed off the mains pipe up to the ball valve then into the pipe just under the tank selector valve which enables me to fill either tank or both depending on what I select. By using this hose I now positive pressure fill the tanks and have rerouted the breathers to behind the toolbox. I blocked off where the old 1" pipe ran into the tank.
I just have to put a fuel filter to the ends of these breather lines to stop any crud being able to be sucked back in.
