What to do if your vacuum petcock is leaking?

I had to rebuild the carb, replace the carb/ intake seal, fuel lines, etc. The petcock was also leaking and HD has no rebuild kit for it so I bought a aftermarket one. It is not vacuum actuated and I was told to plug the hose.

Can a vacuum petcock be used on a carb bike?

HD was ahead of the game with it Carb bikes are gravity feed fuel the Government was looking at requiring different types of safety shut off to prevent fuel leaks. Now with all bikes being EFI it is not an issue anymore. Everyone I know that had a Vacuum petcock fail just got rid of it.

Do you plug just the hose to the petcock?

The petcock was also leaking and HD has no rebuild kit for it so I bought a aftermarket one. It is not vacuum actuated and I was told to plug the hose. Do I plug just the hose to the petcock or Carb, Diaphragm, and pet cock?

When to turn off the petcock on a Harley Davidson?

You will have to remember if long term storage longer than a week to turn petcock to OFF and REMEMBER to turn it back ON as part of your “FINE-C” (Fuel petcock, Ignition, Neutral, Engine Kill & Choke) start ritual, that vacuum operation allowed you to forget about the fuel petcock…no more. You are actually better off with the manual petcock.
