I have the same model van, I would be looking for a kinked suction hose from the tank to the change over valve. What you could do is take off the hose to that tank, at the selector valve, that is giving grief, connect a short hose from the valve and put the other end in a bucket of water, if it pumps, then the problem is the suction hose or a restriction in the tank. Has the problem just occurred, or has it always been there?, I have one tank in my van, that seems to be slow, and am suspicious that the outlet, inside the tank is restricted.

Check and tighten all connections on the hose to the rear tank.

The tanks are connected to the pump via a cheapish selector valve, only one tank at a time can be used. In my case I am suspicious that plastic from the tank molding process is restricting the outlet behind the screwed in tank outlet fitting. gazza I thought you were in Perth until I looked up where you live. I am contemplating moving the water pump to under the floor in a sound proof box, plenty of room under there, installing some better selector valves, and freeing up some room for storage behind the water heater.
