Replacing vacuum lines

[bdubyah]

Hey guys, I've got a 93 with a 350 TBI. I've just about replaced everything to do with the motor at this point except the vacuum lines.

I was wondering if anyone that has replaced them could tell me what size and about how much I'd need. I've gotta order a few other parts and figured I'd go ahead and get them while I was at it. I've replaced the one that runs from the pcv valve to the front of the TBI unit. The rest look to be original.

Thanks guys.
