Got this from work last night. Came from an injector test stand. There were two of them, both identical, one held diesel and the other (the one i got) held hydraulic fluid. Capacity is 75 US gallons and is made of aluminium. A little too big to run as a fuel tank, and is un-baffled inside. Was told, it cost around $650 to have it made three years ago.
