Fuel Starvation / Mechanical Fuel Pump

I couldn't wait any longer. Kids in bed and wife busy on the phone. Time to test the car without the gas cap. I know it's not sunny and 90 degrees. It's 78 degrees and 81% humidity. I drove the car 30+ miles without an issue. Mixed driving, but mostly highway, and no stalls.

Popped the hood immediately, upon arriving home, to see how hot the area is where the fuel line runs by the header primaries.

Here are the results.



I could keep my hand on the fuel line/inner fender area for 10 seconds without crying.



Am I right to think it's strictly a venting issue?
