I have a 95 f150 4x4 5.8 that I took the throttle body off to do some work on and I noticed that the metal tubes that are attached to the tb where the water lines hook to are rusting out. Can these be replaced and where would you get them. Also what size hose are these? Thanks

 

The hoses run hot coolant through the T/B to prevent freezing. They are not replaceable. If your climate is not that cold, you could by-pass the T/B with a length of hose.
