Hi,
This tank takes a very very long time to fill, I have tried all methods with the bowser, driving me nuts so finally went to manufacturers website and it appears to be caused by air lock from incorrect installation of the filler and breather. Other than that it’s an awesome tank.
How do fix this ? Can I bend the breather?
Is this a Professional needed job?
They show the correct way on their website see images below
These two pics are how mine is setup incorrectly
