Vacuum system replacement components
Hey guys,
I'm looking for replacement vacuum components the truck has been whistling like crazy since i've had it. Problem is i can't find anything, just the vacuum can. Anyone know where I could find vacuum components for a 1978 Ford 300 inline 6, with a lead engine?

Whistling is usually caused by rotted out vacuum hose.
I suggest to replace the hoses first.
The first place they usually go is at the transmission of you have an automatic.
What emission parts are you asking about specifically ?

I do not have an automatic transmission. 4 on the floor. Not sure of the emission either i was hoping they made a complete kit... I know there is a vacuum can and vacuum hoses everywhere but i don't know where to start.

Get a can of carb cleaner with a wand ..and start the engine.
At idle,spray the cleaner toward any joints or connections of the vacuum lines and listen for a change in way the engine is running.
I assume you don't have any thermo-vacuum switches on that engine as you never mentioned them ?
Whistles are usually easy to find.
