A leak detection system of a vehicle includes a first minimum module, a first maximum module, a difference module, and a diagnostic module. The first minimum module, at a first time, determines a first minimum amount of liquefied petroleum gas (LPG) in an LPG tank based on a first level of LPG in the LPG tank. The first maximum module, at a second time after the first time, determines a first maximum amount of LPG in the LPG tank based on a second level of LPG in the LPG tank. The difference module determines a difference between the first minimum amount, the first maximum amount, and an amount of LPG consumed by an engine between the first and second times. The diagnostic module selectively indicates that a leak is present in the LPG tank based on the difference.
