Accessible fuel supplies

[BDG]

Siphoning would not work - the siphon out put needs to be at a lower level than its input that would be several feet underground. You could use a handpump to do the job if you can get a hose or something similar into the storage tank - a lot have anti tamper systems to stop this.

You could also use a 12v fuel pump and hose of you have access to the diesel. You would more than likely have a vehicle on hand with a battery that could run the pump and if you are in a situation where you can be retrieving fuel from a fuel tank, you should also be safe enough to take a fuel pump from a nearby vehicle.

Some older diesels do have mechanical fuel pumps so this would not work with them.
