Under slung tank

Discussion in 'Mech Tech' started by SkutterBob, Dec 7, 2023.

  1. Hi,

    I took a punt today and bought an under slung tank for £60. Looks in decent condition and has still got some lpg in it.

    Thought I would give it a quick test outside and instead of gas coming out of what would be the connection to the bus, it leaked out around the red handle. I am guessing something is wrong? What do I need to fix?

  2. Been there , done that !
    Personally i`d bin it and if you fancy a tank splurge out for a new one as from experience it`s a dead end trying to get the correct parts to make it work safely . I did get mucho help from someone on here @Gasman1 maybe ??

    Good luck :thumbsup:

    :hattip:

  3. The valve with the red handle ;)
    Cant tell from the angle but there may be a smaller nut between the red handle and the hex head you can see in the photo.
    If so that will be to get at the stuffing gland and tightening it a little may cure the leak.
    Other than that its replacement, if you can find one, and losing what gas is in it to do so.

    Oops, hopefully you can fix it.

    I bust my valve properly so need to change them and found with my American one that the threads are possibly British or American and the parts are difficult and expensive to find. I seem to remember about £2/300?

    I've moved over to an internal replaceble tank and am going to hopefully plumb it in properly this winter and may eventually move to a refillable one that sits inside but can be filled from the outside here and in Europe.

    The modern underslung tanks, imo sit too low for my comfort, but other on here have fitted them.

  5. It is strange that it leaks around the red handle and don't seem to get much out of the van connection.

  6. I took mine out, it's not that it leaked but was too low for my liking, filling it up was fun too...:eek:

    I bought one too.
    It’s on the shelf with the Eberspacher and the diesel heater I bought!

  9. Have Gaslow cylinder in our other van, just top it up at local Morrisons in the Uk, plus side it is well supported abroad. As others have said do you trust old leaky underslung tank, we had faulty underslung fitting set light to our awning many years ago.

    Bin it Stuart. Seriously not worth putting the family at risk.

    If you really want to persevere then take it to a Gas Safe LPG qualified bod and get their opinion.

    Not sure there's anyone on here anymore with that specific qualification. Without it, it's guess work...but you know that ;)

  11. I am going to give it another look over the weekend to see if I can free off the valve. It does close properly as it seems there is a decent amount still in it.

  12. Or might empty it for safety and sell it on.

    It's perhaps one of those things you buy then think hmmm... maybe not.
    You might fix that valve but then you'll wonder about whether it will last, the very old tank and every other fitting and joint.

    Not sure if this is teaching you to suck eggs but bleed it slowly outside. I had to bleed mine down and it took 2 hours from half full. Otherwise if you go fast the valve freezes and stops flowing and you think it's empty and it then starts again when you least expect it ....!
    Good luck with whatever route you take.

    And release it somewhere that the gas can disperse.. not flow down into a dip and puddle somewhere waiting for somebody to make a spark. Go and check out the Darwin awards..

  17. @SkutterBob if you want to persevere, I'll do you a good deal on mine, it doesn't leak, but you'll need a new Flexi pipe for the connection from the tank into the Bus.

    You could make two from one....

  18. I do already have gas on board but it is a 907 and always liked the idea of getting the bottle outside and saving some cupboard space.

  19. I'd agree totally with your logic and it's the same reason I went down the outside tank route but decided against when it involved rebuilding an older tank then offering it up and realised how low down they sit ..
    So , back to the 907 under the rear seat , it isn't the perfect system but works , and if it ain't broke ....

    An alternative that some conversions had was a hole in the floor with a cradle for your gas bottle. Less cupboard space needed. Not keen myself but it's an option.
