The vacuum lines in a 2000 Pontiac Grand Prix GTP are crucial for the operation of various systems, including the HVAC, fuel pressure regulator, and brake booster. Typically, these lines connect the intake manifold to components like the brake booster, EGR valve, and other vacuum-operated accessories. For an accurate map, it's best to refer to a service manual specific to your vehicle or a detailed vacuum diagram found under the hood. If you're troubleshooting, ensure each line is intact and free of leaks for optimal performance.
