Need. to order new vacuum lines for the. old truck since some are damaged. I have been reading and keep seeing different information with some info saying 3mm id lines and some saying 4mm id lines. Can somebody please tell me which line size I need to order? I am replacing the black red and white right. now.
thanks

 

Snip off a short piece of what you need then reconnect it.
Run over to Napa or whatever your favorite place is and match it have the shop match it up (if the hoses are behind the counter).
Have them roll off enough to route like you'd prefer it to be, trim as necessary and done.

 

I bought this kit and am very pleased! More than enough to replace all those brittle plastic hoses. https://www.paragonperformance.com/A...ne-Vacuum-Hose

 

Thanks Tom. I bought some off of eBay and replaced all my broken lines and suddenly the check engine light is gone and has not been back on since. Not sure if it runs better but at least. that light isn't on and if it does come back on I know it is time to start checking codes.
