You only build pressure from expansion of the gasses in tank. Not likely to build pressure when engine is running because you would be taking more fuel from tank than the expansion process. Now, sitting in the sun, not running is a whole different ball game. Some gasoline engines with the tank half way over the engine will actually build pressure in tank while running. When I was at Hickory Hills many years ago, they were running a 656 gasoline on a dynamometer and they ran a pipe out of the top of the gas cap outside to vent the fumes but that was mainly due to the expansion from heat that occurred immediately after shut down as tank was pretty warm (HOT).
