Does anyone happen to know what size vacuum hoses our cars use for the most part? In particular between the boost sensor/blow off valve/intake. I've searched quite a bit and I've only seen talk about the FD and using both 4mm and 6mm hose. I want to think it's mostly 4mm but I want to be sure before I order 30ft of the wrong hose.

 

5/32

 

Thanks! Converting standard to metric it comes to 3.9688mm so 4mm it is.

Haha I feel dumb as I actually have that book marked and didn't even think to look there!

Ah well. If anyone ever needs fittings/hoses/clamps here's a cheap place I was told about by a good friend and where I ordered from. Intercooler Pipe Fabrication - Silicone Intake Systems Auto Parts
