Good luck. When I was positioning in Zambia, the fuel was one problem (or though less so as it was Jet-A1 in this case), the biggest problem turned out getting usable drums to store and transport the fuel back in.
Had to pay a huge deposit and promise to return them too!
Other advise I'd give is take your own fuel pump, with spare filter and some cheese cloth (for when the spare filter goes
) .
If you can, get a battery powered pump, will save you a lot of grinding :-)
