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