Just curious however .Is the valve like a breather that bleeds any trapped air out of the system?
How do you bleed the air otherwise.
many thanks
Could you see anything wrong with the valve top/diaphragm?
I use the Tettra bubbless tanks. I've been using them for 15 years and never had a problem with air in the fuel.
I don't do anything special when fueling. As long as the fuel pick up is always in the fuel, then it won't get air in the system.
