Vacuum Advance Line - Holden HD HR X2 Stromberg

Holden X2 Vacuum Advance Line – Distributor to Carburettor

• Factory-style metal vacuum line for Holden HD HR Dual-Carb X2 setup
• Connects distributor vacuum advance to carburettor port
• Restores correct ignition timing and drivability

This vacuum advance line is designed specifically for Holden X2 engines, replicating the original factory routing between the distributor and carburettor. Correct vacuum advance is essential for part-throttle drivability, fuel economy, and engine cooling. The line transfers vacuum pressure—not airflow—to advance ignition timing under cruise conditions.

Manufactured from bent metal Bundy tubing for OEM-style fitment and durability. A vital finishing touch for authentic X2 restorations and performance-tuned Holden sixes.

Features:

• OEM-style metal vacuum line
• Fits Holden X2 179 and 186 engines
• Directs vacuum from carburettor to distributor diaphragm
