Fuel system diagram - 2005 Honda Civic

I can provide you with a general fuel line system diagram for a 2006 Dodge Grand Caravan with a 3.8L engine. However, keep in mind that the specific layout of the fuel lines in your vehicle may vary depending on the trim level, optional equipment, and other factors.

Here is a basic diagram of the fuel line system for a 2006 Dodge Grand Caravan with a 3.8L engine:

Fuel tank
Fuel pump
Fuel filter
Fuel pressure regulator
Fuel rail
Fuel injectors
Throttle body
The fuel tank stores the fuel for the vehicle. The fuel pump, located in the tank or along the frame rail, pumps fuel through the fuel filter, which removes impurities and debris. The fuel pressure regulator helps maintain the correct fuel pressure in the fuel rail, which supplies fuel to the fuel injectors. The fuel injectors spray a fine mist of fuel into the intake manifold, which is then drawn into the engine through the throttle body.

I hope this information helps! Let me know if you have any other questions.
