'79 Moonraker tech help needed.

Discussion in 'Mech Tech' started by PANZER HUND, Apr 26, 2020.

  1. I am restoring a 1979 Devon Moonraker, I now needs little technical help after searching the internet to no avail.

    My bus a RHD and just behind the passenger seat on the bulk head are 3 screws in a vertical line that are apparently to hold a bracket for the fresh water filler.

    I would like to know how and where the piping leads to and how the fresh water container is held in place and where.

    Pictures would be a great help if possible. Thank you in advance once again.

    This is the picture of the screws I'm talking about.

  2. The piping goes from the water filler, down through the seat pedestal and into the water tank under the floor.

    The water container is a big oblong plastic tank which rests on a couple of iron straps pretty well directly beneath the front seats, below the floor. There is a drain cock at the rear.

    There's a big round thing under my front seats.
     
  7. The tank goes behind the Cross member directly behind the front beam. Filler pipe routed as the chaps above say, down via the wheel arch/seat tub. I've fitted one to my bus, some info in this thread:

    I like the idea, at the mo I have a 25L(?) portable one in a cupboard with a pump in it.
    Then I think that to fill an underslung one I'd have to take the whole van to the tap.
    Which is better? I can clean out or easily replace my cupboard one and nip to the tap. I don't wild camp.

    I'm suspicious of what happens when you accidently overfill the ones with the indoor filler behind the passenger seat. I guess it soaks into the sponge backing of your tub mats. Devon wouldn't have cared, it was a "feature", it looked neat and had a chrome cap.

  12. I have mine purely as a space saving feature, along with the underslung lpg tank and propex. Maximum space inside for gear on long trips.
    I have the filler inside the wheel arch, mainly as I didn't see the point drilling a hole and putting the filler neck inside as per Devon. I've got a hoselok connector on it for easy filling up at home.

    How big (litres) is the tank?
     
  14. Haven't actually measured it empty to full, I would guess 30 litres ish.

    I have a 9 gal CAK underslung one, goes between the sill and rail on the sliding door side, I have put a step in front of it.

  16. Some piccies of mine. Note how the drain tap is damaged. It's the first thing that grounds on an uneven campsite! Repeatedly repaired using a large soldering iron. :thumbsup: I measured it some time ago, seems to be about 40 lts.

    Definitely. At least its galvanised steel straps. But I would take it off and square up the straps.
    And consider redesigning the draincock - use a flush fitting like the oil strainer cover and bolt in it rather than a tap you would be using once or twice a year.
