Yes, that red clip comes off. It's used on that vapor hose, as well as the fuel hose/line going into the HPFP. I grazed that red clip when trying to remove the PCV hose and it just snapped in half, like the plastic degraded.
The red clip is used to prevent that black clip from releasing the fuel line. Any ideas on where I can get a new clip?
What's the part # for that vapor hose assembly you have up there?
