A system for transferring and igniting a fuel comprising a fuel supply and a cryogenic fuel processor connected to the fuel supply and operative to remove impurities from the fuel. The system includes a power supply and an injector-igniter. The injector-igniter includes an injector housing connected to the power supply and having a fuel inlet connected to the fuel processor. An actuator body is disposed in the housing and a conductor sleeve is connected to the power supply and supported between the actuator body and injector housing with a first annular gap between the injector housing and the conductor sleeve. There is also a second annular gap between the actuator body and conductor sleeve, wherein the first and second annular gaps are in fluid communication with the fuel inlet, whereby fuel provides a dielectric between the conductor sleeve and the injector housing.
