So while doing my PCV system, I've noticed that the vacuum line (evap line?) going into the middle of the intake has seen better days. This also goes for the hose going back to the turbo compressor from the t-pipe(s). Based on my research (with very little help from the VIDA diagrams) it appears this is an 8mm line and since metric hoses are damn near impossible to find around here, I went ahead and got some 5/16th line from AutoZone. The only thing is it's noted as fuel line so I just want to make sure that this wouldn't be an issue with regards to the collapse strength. Also, the clamp around the line at the air inlet hose/turbo compressor inlet is something I have never seen before. Just want to make sure this hose is suitable and see if I need a new special connection at the back before I rip the old line out and start to put this stuff in. I've included pictures of the old line, where it connects at the back and the new hose I plan on using. Thank y'all in advance for the help.
