The Webasto 11120811A fuel pump assembly ensures dependable fuel delivery in Thermo E heater applications by using a pump driven via the burner engine coupling. It compresses fuel to approximately 10 bar and supports atomization through an atomizing nozzle, while an integrated electromagnetic valve precisely opens and closes fuel flow to the nozzle. Designed for two-pipeline operation (supply and return), it also requires pre-filling of the supply line and fuel filter before heater start when used with long supply runs over 15 m, check valves above 0.07 bar in both lines, or a fuel filter in the supply line.
