Advance / Retard Vacuum Hose – Distributor Ignition Pipe 3mm x 9mm (10m Roll)

Advance / retard vacuum hose — the small-bore rubber pipe that connects a classic-car distributor's vacuum advance/retard unit to the carburettor or inlet manifold. This vacuum feed adjusts ignition timing with engine load, so a sound, leak-free pipe is essential for smooth running, clean acceleration and correct timing. Thick-wall 3mm bore rubber, supplied on a 10m roll.
