    Hi guys

    Is it possible to change the above type filler for a conventional fuel type filler cap?

    But I'm not sure if the system is pressurised

    That depends on your pump and taps.
    under the taps will be a pair of lightweight wires if its non pressurised (microswitched)
    if there are no wires its a pressurised system.

    It should be viable to change the filler but it will require drilling a much larger hole in the tank to take the boss/stub to suit a larger, maybe 50mm to 60mm, hose depending on the make of filler.....and of course, you could leave the existing hose to fill if you cant get to a tap.

    The existing fill hose will only be 12mm id

    Ah okay thanks

    Where does the pressure come from then? I know that the pump is a whale sureflo. And when I turn a tap on the pump runs even when the tap is turned off. There is also a trauma ultrastore water heater

    Thats a pressure pump so other than the filler nothing else needs changing.

    The external pump is purely for filling....and as i said, can be retained for filling if you cant get a hose to a distant tap.

    The pump will run for a short time after turning off a tap while the system repressurises and the pumps pressure sensitive switch turns it off.

    Ah okay so whatever means of filling the on board tank is irrelevant then?

    I just think a simple hose filler would be easier

    Thanks again

    Another option would be to remove the filler pump and hose from the square fill gadget and connect a hose in its place.

    The speed of filling would be no different to using it as is but would save cutting holes in the water tank and sidewall of the van.
