I was wondering if anyone knows how much of of what I need to replace all the vacuum lines and boost lines, cause I have a bad boost leak and a rough idle so figured maybe replacing all the lines would fix both. anyway post if you know
thanks

Do a search. Theres a guide telling you how much of each size you need and what order to do it in.

This page tells you the sizes and lengths:

But, if you're going to use silicon, you may want to cover the hoses with something since petroleum products eat silicon for breakfast.

 

mazdatrix says how much hose you need to replace the Vacuum lines

86-92 3.5mm 13ft
6.0mm 6ft

well I got two different answers from both posts but most people I have asked said the first one that asked for 30 feet of 4 mm sounds like alot

also I can't find vacuum lines in the size i need but tons of fuel lines will they work or is there some special place to go to get those lines.

p.s. I am hoping I only need 3.5 mm - 13 , and 6 mm - 6 feet

thanks

there is a thread somewhere here that tells you exactly what you need. i used it and it was pretty much dead on. i think karack was the one who posted it.
