Posts 2 & 7 have pictures of the wobble pump in idle mode. Trolleyacc? Dunno about Nangs Gaat but there weren't any at Sepulot. It was aircraft or helistart Landrover.
In theory you could decant fuel straight into the tank from a 45 gall drum by harnessing it in a net. Starting the aircraft up and then lifting the drum with the winch so thay you could siphon the fuel into the tanks. Heard lots of stories about it being done; never found anybody who had done it or was there.
