Abstract: A fluid actuated fuel pump assembly including a body 12 having saucer-like sections 54 defining separate concave inlet 14 and outlet 16 hollows and a cylindrical central section 52 defining a fuel intake passage 48 for admitting fuel and extending in the opposite direction to a fuel outlet passage 50. A first pulse cover 18 is disposed over the inlet hollow 14 and a first flexible diaphragm 20 is sandwiched between the first pulse cover 18 and one saucer-like section 54 to define a first pulse chamber 22 and a first pumping chamber 24. A second pulse cover 26 is disposed over the outlet hollow 16 and a second flexible diaphragm 28 is sandwiched between the second pulse cover 26 and the other saucer-like section 54 to define a second pumping chamber 30 and a second pulse chamber 32.
