So I'm going to be tearing out the old vaccum lines and replace them with new silicon ones. But the top hoses are different sizes. I was wondering if I can make them both 3/8 I.d. hoses even though thr brake booster hose looks to be 7/16 I.d.? I don't want the brakes to be harder to push if I do downsize on thr diameter of the hose. I just want to make sure making them the same sizes that thr car will operate like it should.

I wouldnt change the booster hose size. Its a pretty precisely measured volume of air that effects many aspects of the braking system.

I wouldn't worry about it. There's no flow there, it's just a transmission line to get vac from one place to the other. The important thing is going to be making sure it fits on the check valve.

Ok perfect I'm going to be using a boost manifold for dispersing the vaccum

So somewhat related to this, but my clutch line has failed near the fitting connector to the slave cylinder. And I'm trying to find another fitting for it. Does anyone know where I can get the fitting from or at least another fitting that'll fit.

So the bigger hose is 7/16 and the smaller one is 3/8 for anyone wondering if you need to replace it.
