JLT v3.0 Catch Can Vac Leak

[ict_wildcat]

Lot of posts and threads about catch cans but I didn't see anything on this when I searched, so hoping a few can weigh in.  Installed a JLT catch can on my 2020 LT Trail Boss with the 5.3L 10 speed and have noticed what sounds like an air/vac leak where the hose connects at the intake manifold valve.  When I remove the catch can hoses and reinstall the stock PCV hose the sound is almost non-existent.  No CELs or codes occur when running the can.  Anyone else notice a leak on their cans?  Thanks in advance!

Did you verify the can is sealed well? Remove it and plug one side. You can use a vacuum pump or suck on the other side to see if the seal is leaking.

These are not high tech. Just an inlet and outlet but if the canister seal is leaking that’s a problem.
