Gas regulator for barbeque

[Mushty]

Hopefully the right place for this question - we've just bought a new barbeque to replace the old one (probably 25-30 years old!) but has come with a different regulator to the previous one. I've got an almost full 15kg bottle of gas left so just after advice if it would possibly be any issues taking off the new one and replacing with the old otherwise it's buying a completely new bottle at a hundred and whatever quid. The old regulator although performing well before is getting old now so should I just bite the bullet and get a new bottle?

On the old hose it reads 'BS 3212: 1991/2/8/3 High Pressure LPG 05/100' and on the new hose 'GUANGFENG GF516 6mm EN16436-1-class 2-8mm-10 bar'

The bottle in your picture is not for a bbq (although it will work with the right regulator)

OK, ta - that's the one I've used for the past 25-30 years, maybe time for a new one then!

Thanks for the quick answer.
