I have fitted one of those red JK electric screen washers to my 1968 T2 van and it works fine unless I leave it for a few weeks and then it will only work if I prime it first. I have sited the pump right down at the bottom beside the water tank and bolted it to the metal behind where the kick boards would be fitted, if I had any kick boards. I have also fitted a non-return valve in the pipe about half way up from the floor to the screen. To prime it all I have to do is to disconnect the pipe from just before the non-return valve and switch the pump on and then it squirts out the water with no problem. If I reconnect the pipe to the non-return valve quickly enough it will carry on working and wash the screen. But if I don't use it for a few weeks I'll have to prime it again. If anyone has any ideas as to what might be wrong and how I could fix it I'd be very grateful.
