Help, I can't see...Charcoal Canister Blues Photos Added

[jersey]

Problem solved. It wasn't the little tabs with the 10 for the far hose it was the black part of the 2 knuckles. PLUS once I got the 1st hose off I was able to swing the box all the way down hanging to where it was close enough to see it with my glasses on. Took a little effort to both push it in and squeeze but once it clears the retaining ring on the canister tube it's good to go.

For the middle tab, same thing, push it towards the canister, press in the black button and it pops right off. Better still on reinstall, it pops back on.

Codes PO 442 and PO 455 are both gone!
