Code P026D and split cold side CAC pipe

I'm aware of the rolled bead and its purpose, but decades of experience has shown me that all too often people seem to think hose clamps absolutely need to be reefed down until the hose bulges, then add another turn or three. That's not to say I'm a fan of the stupid hose connector design we have, but the clip isn't the problem. Some of our fittings use o-rings, others use a single or double lipped seal. Good news is the seals are usually easy to replace and cost less than a hose which's been mangled by a hose clamp gorilla.

The issue is they don't sell just a replacement o-ring. One must purchase the whole piece.

Nobody says that you can only buy a replacement o-ring from Mopar. Pull the old one out, measure its ID, OD, and thickness, and find a suitable replacement.

So I've added some PIDs to the diag screen on OBD Fusion. Commanded VGT A Position, VGT turbo A Position, Commanded Boost Pressure A , and Boost Pressure A. So far everything is lining up within reason driving locally. Will be cool the check this while towing and under a sustained load.

The PID I'm using for a gauge is "Boost Psi" and again....21.9-22.1psi is what I'm seeing as the norm at my 500-700' elevation.

"Atmospheric pressure" is reading 14.4psi so that is consistent with my elevation.

Mine boost max out at 23 psi since new. My commanded vs actual position VGT is off by about 1.5%.

What I'm trying to say is why makes thing more complicated to repair. Trying to find a compatible Viton oring would be tough.

It looks more like a tapered seal to me than an oring? I would guess by design, the pressure probably tightens the seal.

I can't find a picture and the oem part label pic shows it as a nut, but many descriptions online list 68364983aa as a 55mm seal? Could this be it?
