Super easy heat soak / vapor lock remedy for Jeep 4.0 engines. While it might not go away completely depending on your issue, wrapping it with this kit noticeably reduced mine by what feels like 90%. You may want to use zip ties to keep the fuel line wrap in place - mine started drooping into my driveshaft as you can see.

What were the original symptoms? I have a 2008 GC with what seems like a vapor lock issue. It cold starts fine 100% of the time but after going for a drive and turning it off, if i try to turn it back on within 5-20 mins it will not turn over. I have to wait 30+ mins for it to cool down

Mine were very similar to that. When I’ve been at operating temp for a while, and most often when off-roading/starting back up (especially when on an incline/decline) it barely achieves adequate idle and I have to feed it gas. After that it was a rough/weak idle and misfires, usually followed by an engine code. Quintessential vapor lock/heat soak. This kit tamped that down by what feels like 90%
