Sure thing! Here’s a basic vacuum line diagram for a 3.8 GM engine from the 3800 Series 2:
- Brake Booster Line: Connects from the intake manifold to the brake booster.
- PCV Valve Line: Runs from the PCV valve to the intake manifold.
- Fuel Pressure Regulator Line: Connects the fuel pressure regulator to the intake manifold.
- Evaporative Emissions Purge Solenoid Line: Goes from the solenoid to the intake manifold.
- HVAC Control Line: Links from the intake manifold to the HVAC control.
- MAP Sensor Line: Connects the MAP sensor to the intake manifold.
These lines carry vacuum pressure to various components within the engine system to assist in their functioning. Always consult the specific vehicle manual or a mechanic for accurate and detailed diagrams tailored to your vehicle model.
