Mechanical Pump with Return Line- input/pictures/etc.

OK so I checked All-knowing Google, and he says richmond VA is about 166ft above sea-level and the summer time high temp is 69.5.
What I want to know is how on earth you can be cooking your gas under these conditions.
I run my cooling system at 205*F, so my 7-blade fan is pounding heat under my hood, and my aluminum heads are gushing heat under the hood, and my uncoated TTIs are also pouring heat. And my fuel lines are un-insulated, and my carb is bolted to the intake with nothing more than the 1/4" or so standard paper spacer,and this thing has done 4 back to back 1/8mile runs with about 10/15 minutes of idle time in the line-up, on a near90* day, and it went 93mph on the last run. After the last run it was back to the pits,hang the exhaust system, put the street tires back on,reload, and off to the parking lot we go. Some 3 hours later, my son and I had our fill of that and we jump into the car and off we go.
At no time was there a hint of a fuel issue.
And my pump dead-heads at the carb.
And I run 87E10 (right now,yesterday at $0.88 a liter,Cunuk)
So tell me AJ, what's yur point? Ummmmmm, oh yeah; are you having an issue?, or are you attempting to avoid an issue? Or at the risc of sounding like an aZZ,do you just have nothing better to do, or spend yer money on? Ino,Ino, that's harsh. Well only if it's applicable. I just can't understand vaporloc at 69.5*F and 166ft.elevation.Or even, as in my case; near90*F and 880ft.
