Abstract
Disclosed herein is a fuel supply comprising a compressed gas chamber and liquid fuel chamber. A pressure regulator connects the compressed gas chamber to the liquid fuel chamber. The pressure regulator is capable of taking a high pressure input from the compressed gas chamber and providing a substantially constant lower output pressure to the liquid fuel chamber. The pressure of the compressed gas chamber can decrease over time, but the pressure that urges liquid fuel out of the liquid fuel chamber remains substantially at the same level.
