Does the plumbing from the BPV to the intake before the turbo need to be able to withstand the same PSI levels that the plumbing from the turbo to the intake manifold?

I was thinking not because that side of the intake system is the side with the MAF and filter and that end isn't sealed and I'm thinking there won't be the same level of pressure coming through the BPV to recirculate.

Reason I ask is, I don't think my plumbing is going to hold up to pressure from the BPV to the intake. It might but I'm unsure.

There shouldn't really be any pressure build up in the piping before the turbo. You will likely have a minor pressure gradient leaving the BPV. This would only likely affect the connection point of the hose hooked up to the BPV.

I'm slightly worried about that part the most actually. There's a hose coming off the intercooler to the BPV and it's only pushed onto the piping and can easily be removed by pulling if off. It'll probably see 17+ PSI since it should be under the same pressure as the intercooler itself. Maybe I can put a hose clamp on it.

I would definitely put a clamp on the intercooler side of the BPV hoses...this side is pressurized anytime you build boost and will slowly work the hose off the fitting.

fwiw my post bpv plumbing is rigged from clear plastic tubing and elbows, zip tied connections with no blow off(no pun intended). stock boost tho. ditto on clamping the pressure side.

I put a hose clamp on it. There was only one place in the plumbing that wasn't clamped and that was right at the intercooler. You can see it here:
