Save up your old ones. You guys have got to have bunches of them around. Especially guys that are running YS DZ's

Scrounge the local club members. Its easy to come up with a batch of them. Order your drum of fuel and wait till you have the empty jugs to drain it out. You can get pumps fairly cheap or one time we just put a tap in it and tipped the barrel on its side and drained it like a Beer keg.

Worked pretty well.
