3.3TT Aftermarket hoses for BOVs

[Michael Hespe]

Can anyone point me into the right direction for now lines for a set of new BOVs. I am getting the GFB Kit4 and want to swap out the lines if possible add some color maybe? Any help would be much appreciated.
Also just heard the HKS and holly shit they sound nice but they dont have the adjustment like BFG does. Any downside in going with the HKS? I was planning on running about 50% recirc / 50% blow off. You can't do that with the HKS correct?

THANKS

Is it a 4mm vacuum line?

 

[Rodtheviking]

Believe it is, Mishimoto calls it their 10mm line,3mm wall (x2) with 4mm opening.

Ordered the Mishimoto line and it is NOT it. Their dimensions are not even close.

Can you elaborate?

What size are they?

 

[Rodtheviking]

The opening itself is 10mm not the overall hose size.

Is this the stuff, that doesn't fit?

Yes.

I might just use it for my catch can lines.

Hose is 20mm diameter with a 10mm opening, defiantly not going to work as vacuum line for me.

Factory vacuum Tee fitting is 5mm diameter, so you need 5mm ID (inner diameter) hose to fit it properly. OD (outer diameter) doesn't matter at all, but will affect which clamps you can (re)use.

I just ordered some of this: https://a.co/d/7gsrmw3 which has an ID of 5mm and an OD of 11mm:





Which arrived today, along with some of these...




Which seem to fit together well, but I'm definitely going to need some hose clamps because silicone is slippery stuff inside and out. The nipples on these brass tees grip well, but just a little twist in either direction followed by a little wiggle and they start to slide out.

Now that I'm not in "crisis mode" I, too, want to look around a little. I'm going to keep the brass T-fitting because it's *way* nicer than the brittle OEM plastic one, but the freedom to find other hoses is just too good to not pass up.
