A piston fuel pump for an internal combustion engine includes a pump cylinder and a pump piston slidably accommodated in the pump cylinder. The piston fuel pump has a supporting and sealing assembly for the pump piston. The supporting and sealing assembly includes a guiding region configured to axially guide the pump piston in the pump cylinder and a sealing region having a sealing lip.

The invention joins the intake module or intake tube to the engine with the aid of a displaceable retaining element. The retaining element, which in the mounted state is under initial tension, is braced against an engine retention face associated with the engine and against at least one counterpart intake module retention face joined to the intake module or intake tube. Because of the displaceability of the retaining element, the expense and effort of mounting and dismantling the intake module or intake tube to the engine by screws are substantially reduced. The engine is intended in particular for motor vehicles.
