The air gap and reflective white surface works. Is it as cold as AC? No.

THAT's my dream coach! Gauges as far as the eye can see.
From his 3-tank article:
"Last summer, during a trip to the east coast, I experienced vapor lock problems when forced to idle on 100°+ days for more than three minutes. When I returned home, I abandoned the stock steel fuel line that ran inside the frame around the engine and ran a new steel line outside the frame. When I finished this task, it was 105° in Ridgecrest and I drove to a large empty black asphalt parking lot and idled for thirty minutes with no vapor lock problems."
From the Western States article:
"The hottest fuel temperature I have observed was 148 degrees – twice. Once on Baker Grade on I-15, and another time on I-84 east of Portland, OR. In both cases it was August and the outside temperature was 115 . The temperature outside the frame was 122 . On I-15 Baker Grade with two fuel tanks, the front tank was 5 degrees hotter than the rear tank. On I-84 with three tanks, the front tank was 5 degrees hotter than than both rear tanks.
Generally speaking, my fuel temperatures run 30 warmer than outside temperatures. After installing heat shielding between the exhaust pipe and the fuel tanks, I could not detect any change in fuel temperatures. ...Right now, I am not experiencing vapor lock but I have been here before!"
Is Chuck's coach carb or efi?
