Vapor lock possible in 4.8 2008 TJ Jeep. I have the wix corvette filter regulator setup with the oem 1997 TJ in tank pump. On a hot day if sitting idle will starve for gas smells lean and die, after it cools it runs fine. I used a temp probe and the fuel line leaving the regulator is 140 deg F on a 95 deg day. I wrapped the exhaust next to the filter. The above temps are after I did the wrap. I also installed a small alu shield over the regulator. Does this sound like Ive done enough or do I need to think about re-routing the exhaust???
The above pic shows were it is the exhaust is about two inches away and exits the rear durring build
below is after I wrapped it
plastic wire tie is temp
