  "textContent": "A fuel pump for pumping fuel to a fuel valve. The fuel pump has a housing with a first bore (84) and a second bore (81). A hydraulically driven actuation piston (83) is slidably received in the first bore (84) and configured to be movable between a retracted position and an extended position. A drive plunger (80) is operably connected to the actuation piston (83) to move in unison with the actuation piston (83). The drive plunger (80) is slidably received with a first clearance (91) in the second bore (81). A pump plunger (87) is slidably received with a second clearance (92) in the second bore (81) and configured to be movable between a retracted position and an extended position. A sealing liquid chamber (86) is arranged in the second bore (81) between a distal side of the drive plunger (80) and a proximal side of the pump plunger (87). A pump chamber (82) is arranged in the second bore (81) on a distal side of the pump plunger (87).",
