ABSTRACT:
A fuel delivery system for an engine is disclosed which includes an injector (20) and a housing (3) for supporting a fuel injector (20). A regulator (202, 313) is provided for regulating the pressure of fluid in the housing to maintain the pressure at about supply pressure, and the pressure downstream of the regulator at a low pressure so that fuel which passes the regulator is able to evaporate. The evaporated fuel is supplied to a heater (250) to heat the fuel, and the vapour is supplied to a vapour injector (260) for injection into the engine. The passage of the liquid petroleum gas fuel through the housing (3) cools the injector (20) to maintain the fuel in a liquid state, and therefore prevent boiling of the vapour within the injector.
