I'm doing a new engine install and I'm replacing all of the hoses.What size are the vaccum lines on an 87 TII? Are the majority 4mm or??? And what size are the fuel lines? Also need info on where to get caps for the coolant nipples. Can any of you guys help me out?

 

The fuel lines are 5/16 or 7.9mm and you want to get the high pressure ones. I got a variety pack of different size caps from Pep Boys.
