Vacuum Line Size?
I'm looking at replacing my boost / vacuum lines and was wondering what size(s) to purchase? I have seen 3mm, 3.5mm and 4mm on various websites. Also, how many feet/meters does it take to replace all of the lines?
Thank you in advance for your help. Last edited by whosdady; 03-04-2013 at 02:07 PM.. |

Did you order the 3.5 mm (1/8") or the 4 mm (5/32") one? Feel misled because some people so go with the 3.5mm and others say 5/32"

I ordered from FCP
https://www.fcpeuro.com/products/bmw...-11731259996-5 5 meters is about 16.4' and I had about 3' left over. I routed mine a little differently from stock. |

either 3mm or 4mm hose should work. I would try the 3mm to ensure the hose doesn't come off of the connectors. Also, make sure you get hose that is ok for high heat. No wiper fluid hose!

4mm is too big and will slip and cause leaks. 3mm is too small and difficult to fit. Hence the need for 3.5mm -- why cheap out with the wrong stuff? Spend more for the right size and be done with it.

Anyone have issues getting the hose back on the rear waste gate actuator? I don’t have big hands or forearms but I can’t get the booger back on for the life of me. The nipple feels like it’s flared out if that’s possible. Would it be easier to try from the bottom? Or perhaps if I move the coolant reservoir???

I struggled hard on that one, but eventually got it on working from the top. It was a bitch. The trick was to spray some silicone on the inside of the hose, but not get any on the outside or on your fingers making it to slippery too push on.
