I dont think
oil was the issue. Looks to be a really cheap casting. It was the 2 guage type with the 't' handle. It broke around the top of the thread that holds the diagram on and also where the T handle screws in. Was a clean break and looks to be a crappy casting, i guess it has just become brittle over time.
Rob,
I have my own D size bottle that a friend will be filling for me in the future, but at the moment his hose that he uses is broken so i rented this one from BOC. It was about $100 for D plus $13 per month rental. I am building my fuel tank at the moment so this bottle should get that job finished.
There is another company that competes with BOC, they are called supergas. I was told it was set up by an ex BOC person. My mate who will be filling my bottle for me next time, pays $75 for the big bottle that is about 6ft tall through supagas.

The guy on ebay that Boxhead linked appears to be cheaper than BOC once you have the bottle.
Jamie,
