Fuel Rail Pressure Sensor Wiring Diagram & Workinghow to diagnosis & working Fuel Rail Pressure Sensor with help with wiring Diagram & testing with Multimete.. NOTE: Any change made in fuel pressure will change the fuel bowl float level requirements. A readjustment in fuel bowl levels will be required for proper operation of the fuel system. WIRING THE FUEL PUMP: NOTE: A fuel pump can be wired as shown in figure 2, but the preferred method is wiring it through a relay, as shown in figure 3. 1.
