Hello, I'm Chris.I will do my best to answer your question fast and accurate using the info you have provided. Thanks for visiting Just Answer.
Are you wanting to fix the vacuum actuator or just alter your hubs?
Ok I need to know what tests have been done on the actuator and how has it failed. Have you taken it apart. From inside the PVH you can only correct vacuum leaks with sealant or rebuild the relay internal which controls the magnet. Ford offers no internal diagrams of the PVH
All the fittings should be reusable and zip ties can be used were needed to secure any that are loose. I would get at least 12 foot of hose so you have enough. Its only like 2$ a foot.
The PVH is behind the passenger side headlight.
