Vacuum Switches

4 produits

Vacuum Switches for Harley-Davidson are the fuel-tap actuators that use engine vacuum to open the petcock and allow fuel flow when the engine is running. Stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these switches fit FXR, Softail, Dyna and Sportster models from the 1980s and 1990s. Standard leads the range with direct-replacement vacuum-operated petcock diaphragms and complete switch assemblies. A failed vacuum switch causes fuel starvation or constant fuel flow, so replacing it at the first sign of trouble keeps your carburettor fed properly and prevents the flooding that can wash oil from your cylinder walls.
