I just ordered hoses to change all the vac lines in the engine bay. 4, 5, 6 and 8mm reinforced rubber hose (gates fuel lines) which I found here: http://www.mkivsupra.net/vbb/showthread.php?132227-replacing-the-vacuum-lines/page3
But there are a lot of tiny hoses on the intake manifold and they are a lot smaller, and I was wondering if they are all the same size and what size is recommended. I think that normal silicon hose is best as they are not as thick as the reinforced rubber ones. Or could I just use the reinforced rubber hose? I ordered plenty of every size.
