vacumm line help

[djs1w3]

Hey guys iv been searching this for a while now and i cant really find anything
Iv got a 98 ranger extended cab xlt 2 door 4x4 offroad with the 4.0 v6 automatic.
I need to know the size of the vacumm lines like all of them my truck is running like absolute doo doo and the only thing i can think of is vacumm leaks at this point.
Any help is appreciated thanks

In cases like this. Just grab a sample of what you need to replace and take it to the parts store.
