A bypass pressure control unit for use in bypass relation to a fuel delivery line of a pump operated fuel delivery system for an internal combustion engine. The unit includes a housing that encloses a flexible diaphragm valve for defining with the housing a first bypass outlet chamber and a second fuel inlet chamber. The housing has a fuel inlet for communicating the second chamber with the fuel delivery line. The regulating valve is a flexible diaphragm membrane biased by a spring into direct engagement with a relatively large diameter valve seat formed...
[ What is claimed is:] [1.] A method of delivering fuel to an internal combustion engine that includes:a fuel supply with a fuel pump responsive to application of electrical power for supplying fuel under pressure,fuel delivery means on the engine,a fuel line having one end connected to an outlet of said pump and a second end connected to said fuel delivery means,a check valve in said fuel line for preventing reverse flow of fuel from said delivery means to said pump,fuel bypass means coupled to said fuel line between said second end of said fuel line an...
