As my LPG tank is now empty i would like to remove the gauge and invetigate why it is not working (think it has been posted previously how to fix if it has a hole in the float)
If i do manage to fix it how do you reseal the gauge? Is there a gasket that needs replacing?

Thanks

Steve

I removed my to respray the tank, I reused the gasket when I refitted the gauge - no problems after 1 year.

Just be careful when you remove the gauge, ease it away from the tank rather than yanking it away.
You should be able to "save" the gasket.

Excellent. Thanks for the reply. I will have a look after work.

Cheers

My gauge is hopeless, its a 65 litre tank, when the gauge says empty i can get 30 litres in it tops...hahaha

You've, also, probably got a hole in the float, the float is filling full of LPG and sinking.
Take it out, let it vent, seal up the holes - et voila!

65L!! That's a big tank :shock: Think my Westafalia is only 20L.

Hi there....Westy Leisure LPG tank (for cooking/fridge with BBQ take off point) from memory it's approximately 16 litres (just under £11.00 to fill from empty)

I think there are a couple of misleading replies above: firstly..the gauge itself operates on magnetic attraction and isn't physically connected to the mechanism inside the tank (this is just held in place with a couple of screws).
And
Rather than the float being 'holed' as you put it...the LPG actually just seeps past the threads into the float. As in, the float is screwed onto a rod and it becomes loose allowing the liquid to seep into the float past the threads.

When I did mine it was just a question of unscrewing the float (any LPG instantly evaporates away) then the float is resealed using 'gas grade' PTFE tape on the threads of the pivot rod.

As for the mechanism itself: this is held into the tank with 4 allen screws behind the gauge. Release and tighten evenly, I also re-used the 'O' ring seal without issue. Extract the mechanism to remove the float on the end of the pivot rod arm. Once re-sealed the float will correctly move and the magnetic attraction of the mechanisms internal magnet will then operate the external gauge.

Sorry but mine is physically linked through two gears and has no magnets.

The one on Gunzl's website is totally different than the one fitted to my tank

Sorry but mine is physically to the gauge as comes out as a single unit.

YES! but look at the gauge....it has two philps heads and a plastic bezel holding it in place.....the mechanism doesn't go all the way through to the gauge. Don't take my word for it, undo and remove the gauge.....unless there were different types?

Semantics - the whole unit is sold as a gauge (unit), you cannot just buy the gauge itself.
When the OP posted about their gauge I am fairly sure that he meant the gauge unit (but then again.......).

I'm not sure what you are saying but how the gauge is supplied new is imaterial if it can be easily repaired without the need for replacement. However, I concur that if the 'display' part of the unit is broken then the whole of the mechanism would need replacing, so in that respect I can see where you are coming from.
All I can add is that in most cases I have seen, the dial display is fine but not moving properly due to internal mechanism failure ie: the float is full of liquid gas.
