Replacing Hoses--What size and how long?

Hey Y'all,

Truck has 250k miles and its about to get a makeover. My hoses hoses look alright, but I figure if I am going to be replacing all my gaskets and other things; I might as well replace my hoses.

I have no clue what the hoses names are, but they are thin black ones with some possibly as thick as a pencil and some a little smaller.

Can anyone help me with the names of these, the size, and how long of hoses do I need?

Thank you,
Trapper

 

More than likely they're the vacuum hoses.

 

It sounds like you're talking about the vacuum hoses. I'm not sure which engine you have, but presto (member here) recently replaced most of his hoses and posted sizes and lengths in his build thread. He has a 3rz so I don't know how much they differ if you have a different engine.
