I have a 5.0 from a 99 Explorer I will be hopefully using in a project. One thing that has me puzzled is the fuel system. It only has the high pressure supply line to the fuel rail, and a vacuum operated pressure regulator in the rail, but no return line to the tank. I am familiar with the type of returnless system that uses a pressure/temp sensor in the rail to control the amount of pressure the in tank fuel pump develops, but not this setup. Someone care to learn me on how it works?? My plan was to fabricate my own fuel tank that would gravity feed into a late 80's Ford truck inline high pressure pump. Will that idea still work with the returnless system on the engine I have?
