Fuel Flow Analysis

Js550 fuel line diagram

Fuel flows from the fuel tank to the fuel pump, which pressurizes it and sends it to the fuel filter. The filter removes impurities from the fuel before it reaches the fuel pressure regulator. The regulator maintains optimal fuel pressure for the fuel injectors, which spray the fuel into the engine’s cylinders.

Fuel Pressure Regulation

Js550 fuel line diagram

The fuel pressure regulator ensures that the fuel pressure remains within a specific range. It does this by controlling the flow of fuel through a bypass valve. When fuel pressure is too high, the valve opens and allows some fuel to return to the fuel tank.

When fuel pressure is too low, the valve closes and restricts the flow of fuel.
