does it really matter what kinda vaccum hose you buy. not so much length but the width on the inside.
thanks for the help
ouch

 

i know the quality does matter, i've had some melt on me and thats no fun. But over all i dont see a reason why you would need to use larger then 4mm on most parts and 6-8mm on some others.

 

i just finished my vacuum hose job. i only used 3.5mm for the smaller hoses and 6mm for the larger one. there were a few times where i could have used a larger size than 6, but those are the two sizes you really need.
