I know what a burst disc is. I think I have spotted where its mounted now in the pictures on the first page. The base of the ram is propped up against it which is what was confusing me.

Chris, where did you get your Burst Disc units from? Ebay and Google are only showing units that blow at a minimum of 1800psi, I need around 200-260psi for a low pressure system.
