    I have just bought a new Hymer B678 with the gas bottle compartment next to the drivers seat. I want to refit my Gasit refillable system in this and want to have an external fill point this time round.

    Has anybody done this on a recent Hymer B class and if so where did you put the external fill point and how did you run the filler pipe to it?

    The easiest appears to be low down on the skirt just to the left of the gas compartment's door as you look at it. But I am not sure about that because it seems a bit low for convenience. Also I am concerned about the fact that the skirt is slightly rounded and I am wondering how well the filler point will sit. Also worried if the skirt may not be strong enough to take the weight of the filling nozzle. Has anybody put theirs on the skirt please and how successful has it been.

    Thanks in advance for any help you can give me.

    Fitted mine on the skirt..

    to give the filler point some rigidity I fitted a short piece of angle ally between the skirt and the chassis rail.

    Thanks for the answers so far and please keep them coming.

    Mousy - I could fit it in the locker, as that is what I did on my previous van. But I am worried about the increased banning of refueling like that by garages.

    Jim - that is is the area I was thinking of putting it because it is nice and easy. But my skirt is more curved than yours appears to be. It is made up of one continuous width of ali and there are no pop rivets showing like yours and Tony's. Obviously Hymer have have changed them recently.

    Tony - I do not have as much distance to the wheel arch as you do. In theory I could put it a bit higher (which would be OK by me) but I can't find a way to get to the back of the panel at that point - seems to be hidden under trim in the driver's cab area.

    You don't really eve want the tube entering cab even for a short distance. In the unlikely event that it gets a leak it would be pooling in the cab low points.

    You can download the fitting guidance from Gaslow..

    https://www.google.co.uk/search?q=g...-8&oe=utf-8&gws_rd=cr&ei=UW1VVoenKMr3UsTjjMgN

    I have just contacted them as I was told (on another forum) that my regulator should be above the bottles.. otherwise I may get residue into the regulator..

    As far as I know this was only a problem with the old rubber hoses.. Gaslow now supply a s/s hose that is not affected in this way... my regulator is where it was while I had Calor bottles.. so don't see why it needs to be higher.. but I await Gaslow's reply and will post what they advise..


    If you look at the photo in the fitting guide, it is a Hymer and as far as I can make out, (photo 7 and 8 ) the regulator is below the top of the bottle .. they make no mention of regulator height in the instructions.

    Thanks for that Jim. Yes it does look like a Hymer doesn't it. Unfortunately the skirt looks more like yours than mine, which has a distinct curve on it. I was concerned about how flat the filler would sit on it. I will go out later when I have time and look at it again and maybe take a couple of photos to try and show what I mean.

    As for the regulator height the instructions for my truma regulator says that it should be set higher than the take off point from the bottle in order to "make it more difficult for gas in the liquid phase to penetrate the low pressure area, particularly while driving". Their quote not mine. Mine is fitted horizontally to the top of the gas locker, not vertically to the back like yours.

    Jim, another point to consider is that the Truma is designed for use when on the move and has the crash protection system which switches off the gas if a movement above a certain G force it detected. That has been required by law on all new vans for a few years now if you want to use gas appliances on the move. I know that Gasit's regulator does not have that, but do not know about Gaslow's.

    In addition mine now has a rupture protection hose for the pigtail which switch off the gas next to the bottle if the pigtail breaks. I think that is a relatively new requirement though. Again I know Gasit do not sell those type of pigtails and when I spoke to them they suggested it was not needed because they have a non-return valve. However they were clearly getting confused between a pigtail and a filler hose!

    I have read about the positioning of the Regulator and bottle top v/v and I am sure that they like the regulator higher but not essential. If the regulator is lower or the same height, as long as there is a low point in the hose that is all that matters. What shouldn’t happen is any residual liquid running down the hose and into the regulator.

    If fitting in the skirt why not fit one of the smaller inlets. My gas bottles are in the garage the filler is below in the skirt.

    Thanks. that may be better where did you get the small inlet from please? Not sure how it works though because the gas gun is pretty big! Do you need to screw the filler point on each time?

    Edit: BTW you have the same skirt as mine - is their a problem with it being curved?

    Gaslow just got back to me and yes, they prefer if the regulator is fitted above the bottles, so will do that as soon as the weather gets warmer..
    I can can mount the regulator higher and fit the auto changeover on the roof and connect using a right angled fitting..

    I have an old Hymer and the Gaslow filler is in the locker. I was also worried about filling it. On their web site Gaslow have a list of filling stations in the UK who they have been in touch with and allow this. The nearest one to me is nine miles away although I live in a town with quite a few LPG filling points! I'm in the midst of moveing the filling point to the outside of the van.

    Autogas2000 sell them in the UK, you can get straight & R/A. Link to site. You screw in the appropriate adaptor each time for whichever country you are filling up in .

    Thanks John. I have looked at Gaslow's website and all I can find is the large round filling point, not the smaller square one as in Lenny's photo. Do you have a link please? Or maybe that have stopped doing them.

    Thanks Lenny - found that on Autogas's website. I see how it works now. I assume that my continental adaptors will screw straight in to it as well as the UK one?

    I assume it is OK for a slightly curved skirt? Is it just a case of some mastic or does the rubber seal on the backing bit take the curve up?

    Lenny, does your skirt have reinforcement ridges on the back like mine? Mine have 55mm clearance between them, so I will need a backing plate no larger than that. Is that OK with the one you linked to please.
