P0442 Small EVAP leak - broken canister

[2018GMC]

Several months ago I got a CEL for intermittent P0442. Cleared and went away for months. Recently got it again and now it’s a permanent P0442. 
 

After checking the purge solenoid in the intake I moved under the truck and saw that someone attempted to jack the truck up under the Evap canister. Last shop I was at was Discount Tire / Americas Tire over a year ago. 
 

I guess the code took months to show because the plastic Evap canister was sealing since it was shoved hard into the metal holding tab. After months of road vibration it developed a leak. 
 

A new canister is $150 so I put some JB Weld in the hole along with bending the bracket back down.

Good catch, we almost had matching damage, mine fell off of a small lift at the dealer.

Guess I was lucky, never had any codes show up, so they must not have broke mine.
