Why does the Mega Filter trap air when others apparently do not?
The deep drop of my suction nipple, and the internal post seal ensures that there is no channeling of fuel through the threads, and that none of the microscopic filings generated when engaging the filter threads are dropped into the clean fuel below. This also creates a large area for air to collect as the fuel enters the filter. The lazy flow allows this air to rise to the ceiling and collect, waiting to be bled. Other filter designs have less depth to the suction nipple, and apparently allow the air to pass through the system.
