Fuel tanks breathe, as the liquid and air warm up they expand and push out air, that evening they cool and condense pulling in replacement air which is generally very moist and the cycle starts all over again. This happens all year long, anytime it’s warmer during the day than it is at night.
Fuel tanks do not "breathe".
So when I fill my coach, 75 gallons, and then drive 600 miles you’re saying my empty tank is then a crumpled up ball of tin because it collapsed from not being vented?
Or that when I fill my 75 gallon tank with fuel coming out of a buried tank full of gasoline that’s about 50 deg F. and then park it in 90 deg. F. heat the tank somehow expands to absorb the increased volume?
According to the MSDS GM Top Engine Cleaner is (they keep the exact formula secret) 75% or more petroleum distillates, I.E. oil.
