A fuel system for a hydrogen fuelled gas turbine engine (201) comprises a main hydrogen fuel storage unit (104) configured to store liquid hydrogen. The main fuel storage unit (104) comprises an ullage space configured to store ullage fluid comprising gaseous or supercritical hydrogen. The system further comprises a liquid hydrogen drain line (232) configured to provide liquid hydrogen from the main hydrogen fuel storage unit (104) to a fuel conduit (214), the fuel conduit (214) being configured to supply hydrogen fuel to a combustor (206) of the gas turbine engine (201). A priming line (230) is provided, which is configured to provide ullage fluid to the fuel conduit (214), and a priming valve (238) is configured to selectively control flow through the priming line (230).
