Genuine Hepolite Billet Oil Pump Assembly for BSA pre unit singles C,B,M group models (1956-62)

CNC manufactured, using a high grade cast iron body to improve wear properties, with less risk of body distortion than standard, or aftermarket anodised alloy pumps.

Internal gear to body tolerances are much closer than OEM, reducing risks of wet sumping when stood for long periods!

The above notes are our suppliers claims.  Please ensure the pump turns freely befor you fit it.  Make sure you prime the pump with new engine oil before you fit it.
