Many of us seem bothered by petrol pipes, pump and carb getting too warm, and I can remember this being a problem nearly fifty years ago. This made me think - why do the vast majority of cars blow the air heated by the radiator straight onto the engine?
Cold air hits the radiator, then the warmed air is flowing over the carb, pump and petrol pipes. No wonder it vaporises in hot weather. And hot weather leads to more traffic, so stationary traffic has a lot of hot air heating up the petrol.
And to make things worse, the hot exhaust pipe is usually along the same side of the car as the petrol pipe!
Old minis and 1100s seemed rare, in directing the hot air away from the engine, exiting under a front wing. that makes more sense.
Your thoughts?
