YS checkvalve

[Rcmaster199 at aol.com]

The check valve is attached to the vent line such that air can enter the 
tank: ie-point the arrow towards the tank. Fuel is prevented from flowing out. I 
would expect the YSDZ pump to generate enough suction to draw fuel from the 
tank and unseat the check valve to equalize tank conditions.

The valve is removed to fill the tank. It's the reason I need the thing in a 
convenient spot so that I can remove the checkvalve and attach the tank vent 
or overflow to my gallon fuel supply vent. When the tank is filled, no fuel is 
spilled and the exposure to humid Fla air is nil. 

Hope that helps
