Answered- When to replace vacuum hoses?
Answered: replacing now. Thanks!
I've read several times that vacuum hoses last a long time, can be trimmed if needed, etc. But, when do they actually need to be replaced? Mine seem pretty dry and crack across the surface like dry clay if squeezed. To me, that seems "bad" but if I don't need to spend $200+ on hoses, I'd rather not. They do hold pressure when I give them a bit with the handheld (how much should I give them?).

IMO, I changed them when i knew they were more than 40 years and i had access to do so. For instance, if you have the dash apart and the hoses are old, why not change the engine, lights, wiper and even heater control hoses while you have access? The cost of the hoses pales in comparison to the labor time and cost to replace them.

It’s better to change them out by now.
If you think about it the heat cycles they have been through and age alone on those rubber hoses.
beside once all are changed you know that you shouldn’t have any vacuum leaks.
To me that’s the biggest pain trying to find where the leak is without creating a new one trying to fix the old leak..
yes I need to do this as to mine also.
