Beschreibung
Zusammenfassung:	A hydraulic head assembly includes a hydraulic head and an adaptor. The hydraulic head has a first bore and a pumping chamber. The adapter has a second bore. The adapter is connected to the hydraulic head such that the first and second bores are disposed coaxially to form a pumping element bore. A pumping element is disposed within the first and second bores for pressurizing fuel in the pumping chamber. A first seal is formed between the pumping element and the hydraulic head; and a second seal is formed between the pumping element and the adapter.
