For me yes the O-ring 100% fixed the truck

Did you check it you still have problems my truck same issue

Interesting… glad it helped other people, sorry it didn’t help you

Yes, the code never came back after that

I believe I took the pipe or another O-ring (possibly from the other side, I can’t exactly remember) with me to the hardware store and found the best matching size. For me, I went to a place called “Karl’s Hardware” but they are just a small 3 store company in my area. I’m sure other places, maybe even auto shops like Napa etc, would carry one that big. I’ll look through my photos in a bit and see if I can find what size I got (because I usually take photos of everything) and I’ll report back if I do!

Went through all my photos and although I couldn’t find a size, I was able to confirm that I took out the O-ring from the opposite end of that plastic pipe and used that to match the best size for the one that was missing 👍🏻

LOL sure thing. …except that this explains all that I went through to help with troubleshooting for someone else that could be going through similar.
