'10 ECTA rule book, page 14, 2.B FUELS:
In fuel classes, any approved liquid fuel may be used. Examples of approved fuels are: nitrous oxide, nitromethane, alcohol, and hydrogen.
In gasoline classes, you must run fuel supplied by our fuel vendor and have your tank sealed. You may bring gasoline in a factory sealed container to be dispensed by our fuel vendor at a cost of $20 per event. Water injection is allowed, but water tanks must be inspected and sealed by an ECTA offical. Engines using LPG or diesel fuel may compete in gasoline classes.
For all records attempts, the competitor must submit to a fuel tank check in impound after the record run.
