DIY Cigar Smoke Test cured P0442?

Been getting the 'Check Gas Cap' light and p0442 Evap Small Leak Detected MIL.

Pulled out the air box, placed a rubber glove and rubber band around the main air intake tube. Removed the hose off the power brake booster, and blew 2 mouthfuls of cigar smoke into the hose watching the glove ballon up.

Watching the glove it started to go down a bit and I saw smoke coming out of the back under the intake intake.

Cap on nipple had seen better days

Replaced with a new one and repeated test. No more smoke seen.

Location of nipple

Really wanted to tray a vape since they produce so much vapor, but 99˘ vs. vape price...
