Not in the ones I have seen. The liquid hydrocarbon expanded right through the regulator. It was definitely liquid, not high pressure gas, which I suspect would not continue to burn.
A Good Result, First time Try.

Ok so fill to 4 kg then the problem is less likely.
The thing is it is not important to get it full but itis not to overfill.
My figure was not overfill just to close to 100% for some.

out of curiosity, how much does it cost to fill such a 4lt can? I get something probably equiv. down here refilled (well actually replaced with another s/h filled one) for a tenner (euros)
or is it discontinued or something?

FWIW, in France a CG 907 (nominal 2.7kg) refill is around 30-35euro, for 25ish euro I can have an anonymous 10-12kg bottle and fill three or four CG.

Interesting/scary. Apologies if I am coming accross as a pedant, but might that be described as an overfull cylinder, eg110% full? I take the point that it is wise to only go to 4kg /4.25kg. And I take the point that being safe with gas in liquid form is a serious business, which is what you wanted to get accross.

For many in the UK, the popular 4.5kg calor butane has been discontinued, so people are being forced to change, and the solution being pushed to many is camping gaz, which is £45 for 2.75kg (for a 907). For a refill to my 15kg cylinder it was £60, so £16 a kg down to £4 a kg. Greece of course sounds cheaper!

I assume that if the bottle is filled cold, as described above, and then warms up the liquid will expand. Connecting the bottle to the stove could drive liquid through when the bottle tap is opened.
Hydrocarbons have a fairly high coefficient of thermal expansion. I recall that in a saloon car racing series the fuel tank capacity was limited to 12 gallons (possibly USA). Teams found that by chilling the fuel it was possible to get 13 gallons in, not a problem as some was consumed before it warmed up and expanded.
There has been a somewhat similar problem in motorhomes with bulkhead regulators. Liquid fuel getting into the rubber hose between bottle and regulator leaches out the plasticiser, which subsequently driven into the regulator disables it. Gas at bottle pressure then reaches the stove, with unpleasant consequences. I bought a stainless steel hose after reading of this problem.

Thanks for clarifying, that makes good sense.

Eh I remember when I was there a few years ago, the refill of the Spanish "Botella popular" -clone of the 907- was at 10-12 euro, likewise in Portugal, the CG at the time was 25e in France. It seems they fix their prices with a factor of 2, double or half.
Honestly, given my consumption here in local cruising I would not mind either one, it's more the CG business approach I do not like, so I will not buy their products.

The replacement SS hose will, of course, have a rubber/synthetic liner.
Why wont that suffer the same problem you have bought to our attention?

We once had our campervan bottle overfilled and a reputable garage in NZ. Stove was burning very erratic! Another depot weighed and said 'take it outside , let some go' prob solved.

Presumably not rubber, or at least something that is not attacked by the hydrocarbon liquid.
