Mr. Rawles:
Can you direct me to where I can learn how to bury 300 gallon fuel tanks correctly? Also, how to get the fuel out if there is no power. Thanks, – Mark T.
JWR Replies: Unless you expect to use your fuel tank on a daily basis, then I recommend that you install just a manual (hand) pump. These are available from most tank dealers.
If it will be buried in rocky ground, first put down a 4-inch layer of sand, to minimize risk of punctures during installation. Otherwise, burial is pretty straightforward. Be sure to read this general guide on preventing leaks [1] that was published by Oklahoma State University, and this fuel tank safety document [1], published by the state of North Dakota.
If you buy a used tank, have it pressure tested. If you are getting a steel tank, a coating of asphalt emulsion–although it is a messy job–will extend the life of your tank. Also, talk to your tank dealer about installing a sacrificial zinc anode [2] for cathodic corrosion protection. Together, those two measures can greatly extend the life of a steel tank.
OBTW, see my reply to this posted letter [3] for some ideas on camouflaging your tank’s pump head, to prevent fuel thefts.
