When they had to service a wing fuel cell, they "de-fueled" the cell into a tank on a trailer they towed out to the flight line. Then into a storage tank, where it was later disposed of. I have no idea how. :-) the cell would be refilled with fresh fuel after the repair. The cargo planes we had used purple fuel, seems like 114 octane? It was color coded then. We often used fuel from that tank in our cars. Exhaust from a car burning that had it's own aroma. LOL Not hard to tell where some guys got their fuel, in the parking lot at the end of the day.
We thought it was cheap race fuel. We didn't at the time understand that fuel for a 2800 RPM engine was different than fuel for a 8500 RPM (high RPM for the mid-1960s) engine. I was working on 4360 Pratt & Whitney radial engines then.
