Over the last few months I've moved from the traditional steel Propane containers to twin Gaslight containers. I get significantly more gas without any increase in payload. Result! However, I've recently seen adverts for the Safefill containers which you can refill at LPG forecourt pumps. As they are significantly more expensive (about £200) than renting Gaslight bottles, I'm wondering if you can buy adaptors to refill Gaslight yourself?
