Abstract
Fuel supply system for a vehicle engine includes a filter/reservoir housing (22, 122, 222) which is communicated to one or more fuel tanks (12, 162, 164, 262, 264) and to the vehicle engine (14, 114, 214) by a fuel supply line (16, 116, 216) and a transfer pump (30, 130, 230). Excess fuel is returned to the fuel tanks by a return line (18, 118, 218) which also communicates through the reservoir housing (22, 122, 222). Primary fuel pumps (24, 166, 168, 266, 268) pump fuel at a greater flow rate than that of the transfer pump (30, 130, 230) so that the excess fuel is returned to the tank through the return line (18, 118, 218), thereby assuring that fuel being returned from the engine does not mix with fuel being pumped to the engine. The reservoir housing (22, 122, 222) contains a quantity of fuel so that the engine will not be deprived of fuel if the fuel pickup in the tanks (12, 162, 164, 262, 264) momentarily is above the fuel level.
