vacuum hose size?

[JerryH]

Can anyone tell me what size the really small vacuum lines are that are used on the FI system? I brought home some 4mm from work, and it is to big. We don't have anything smaller.

I have a LTD as well and I will check mine next week when I am on days off and see if I can find out the answer for you..
hopefully someone can answer it before I get off work next wednesday but If not I will check mine anyway..

good luck.. :d :d

4mm is .15748 1/8" is .125 i think that will work for you
available at any auto store

1/8" is what I thought too, but would you believe 3 different auto parts stores didn't have that size, and claimed it didn't exist? Yet they have fittings in that size. I found 5/32" is a perfect fit. I just used almost 10' of it. Sorry about all the simple questions, I could (and did) have figured that one out easily. I'm trying to work on this thing in my spare time, problem is, I can't seem to find any spare time. I finally have almost a whole day to work on it.
