I have an mbc to install and I need to purchase some silicon hose to do so. What size of tubing will i need? 4mm? 6mm?

Sitting at work and can't take my car apart to check.

Coulden't find anything with the search

thanks.

 

i have 4mm on mine works good... lil hard to get on dry but guess thats a good thing

 

most of the common mbc's use the 4mm hose

 

for anyone that searches for this later, 4mm fit the best on my buschur mbc. the stock nipples seem made for 4mm.
