PROBLEM TO BE SOLVED: To solve the problem of cost increase due to high production cost of a high pressure pump in the case of independently providing two pumps for supply of two different fuels in a system using the two different fuels. SOLUTION: The pump for feeding two or more different fluids comprises a body 3 having a longitudinal bore 5, and at least first and second inlets 9, 19 selectively communicating with and providing a passage to the bore 5 via non-return valves 10, 12, 20, 22. A plunger 16 is mounted for reciprocation within the bore 5 and at least one piston 14 is also mounted for reciprocation within the bore 5 so as to permit at least one type of fluid to pass into the bore 5 through one or both of the inlets 9, 19.
