Tiga Ordered a fuel pressure tester kit and I’ll check when it arrives.
Yeah looks can be quite deceiving! I’ve pulled it off to clean previously. The thin tube on my Y pipe was snapped off and causing a boost leak when I saw it so blocked it off with a screw and some silicone lol. Pcv seems to be working fine but does anyone know what that vacuum line was for??
It runs to the CBV on the turbo, it opens and closes with pressure. It makes the cool blow off noise when disconnected, but causes the car a very slight rich fuel mix , boost leak, loss of power.
I went ages without it connected, and didn't notice a huge difference once plumbing it back in, it would be worth sorting out though.
