I am looking to change out the vacuum lines in my 13B-REW

I have found tons of stuff all over the internet about the swap my question is can I use 3mm vacuum hose or do I really need to find 4mm

I have about 30 ft of 3mm lay'n around that is why i ask

please let me know
thanks

You will need three different sizes of hose.

3.5 mm
4.0 mm
6.0 mm

Make sure that you are using silicone hoses.

Yeah, and make sure you have a full day to do it cause I believe its about 80+ lines if you still have seq. =)

do one at a time so you don't CAUSE any other issues withthe system. it takes some time but you get to know your car so thats a good thing! Have fun. If it's never been off before(even if it has) The UIM gasket is like around 10 bucks.(metal gasket) replace that while you have it off. stick rags/paper towels in the holes that are open so bolts don't fall in! This sucks!!! Trust me!Good luck.

Ok

so what i am getting out of this is that the hose sizes are spacific
and that you can't use a 3mm hose where there is a 3.5
and so on

anyway
thanks for the replys
