where does all this common rail pressure come from surely not from the punie little lift pump. nope - the electric lift pump only supplies about 12psi or so of pressure. the gear-driven injection pump for 03 and up trucks its a bosch cp3 pump pressurizes the fuel up to about 23500psi again for the 03+ engines. i would have thought that the actuation of the injector would create the much higher pressure. in the older trucks 02 and earlier it was the pressure in the injector lines leading to the injector that would cause them to pop off... somewhere around 3500psi. the pressure had to be created first to get them to open and then the higher the pressure the more fuel that would flow in a given time and the more atomized the fuel would become. on the 03+ trucks the injectors are electrically actuated via a solenoid. the rail pressure is present in the injectors at all times. this gives the computer direct control over all phases of the injection event or events as the 03-04 trucks have two injection events the 04.5+ engines have three injection events per power stroke. to this conclusion because of the location of the lift pump being between the tank and filter. that would make the filter an extremely high pressure can with a low pressure gasket on it. yeah - a pleated paper filter isnt going to hold up to 1600 atmospheres .
