Dear Jim:
There have been a lot of posts recently about bug-out vehicles and such on SurvivalBlog. Of course, every car or truck requires fuel, and in a sudden grid-down situation there will be a bunch of fuel in underground tanks at most every gas station, unable to be pumped out due to the lack of electricity. I have observed oil company trucks filling these tanks, and it appears they simply pry up some covers and drop the fuel into the tanks.
How deep are these tanks, and can the fuel be pumped out by some kind of lightweight hand-cranked pump of some kind, directly into a vehicle tank? How long a drop tube would one need to access the gas?
These questions, of course, bring up the moral aspects of pumping out the gas. In a short-term grid down situation, like is presently occurring in Oklahoma, taking gas without the station being open would clearly be theft. But at the beginning of a long term TEOTWAWKI situation, one might wish to get the gas, and leave payment in cash or junk silver, for example. What are your thoughts on this? Sincerely, – Mark in Albuquerque
JWR Replies: Typical retail gas station fuel tanks are less than 14 feet deep, including the height of the filler necks, so a 15+ foot draw hose is more than long enough. Back in February, I posted details on a safe and cost-effective solution to pumping gasoline from underground tanks without grid power. My design variant (of a time-proven design that has been popular with some dirt bike enthusiasts for more than a decade) uses a 12 VDC fuel pump and incorporates an in-line fuel filter.
Odds are that you will be able to find the station owner to make payment, at least while there is still fuel in their tanks. In fact, any wise station owner will probably hire armed guards, regardless of whether or not power is available. In a societal collapse, with no re-supply in sight, they’d know that any significant quantity of gasoline would have tremendous worth. But of course after the tanks were drained, in a worst case scenario the station would probably be abandoned.
If you build two or more such pumps in advance, then you could probably use the extras in barter–most likely to trade to a gas station owners for some of their fuel.
