Has anyone either put a 90deg bend in the fuel tank vent with the vent hole facing forward or added a 45deg forward facing cut in the fuel tank vent?
The reason being to the negate a lower pressure in the tanks caused by the vents being on the bottom (low pressure area) of the wing and again to stop the Venturi effect on caused by the vent pointing straight down with the end being 90deg to the airflow? I found that I need to do the above to allow the engine driven pump to suck fuel from the tanks in either high altitude, high temp or both situations. Has anyone heard of doing this ?
Thank you in advance for your input.
