The piston Convair fuel system is I believe the same as the turbine 580 series which is very simple. Each wing is one big wet wing fuel tank which feeds its respective engine. The fuel controls are 5 switches. 2 fuel on/off, 2 fuel dump, and one fuel crossfeed on/off. I have not sen the report of the crash you mentioned but I would guess there were other factors which contributed to the crash.
