Abstract

The invention relates to a cylinder head blank (9) for a high-pressure pump (1), which is in particular configured as a radial or in-line piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprising a base (10) having a high-pressure outlet (16) and a plurality of low-pressure connecting points (13-15). Here, the plurality of low-pressure connecting points (13-15) are closed in a raw state, wherein a low-pressure connection (11) can be fitted to each of the low-pressure connecting points (11). The invention further relates to a cylinder head for a high-pressure pump (1) and to a high-pressure pump (1).
