The stock lines are very soft and loose like you said mr240, specially on the nipple inside the tank.

I was on the track this morning, I put another piece of line and the end of the fitting to make it tighter, works great so far, But also I'm gonna try different brand of line. I like the soft ones inside the tanks so the clunk can turn easily upside down.

If this doesn't solve 100% the problem! I would say the fittings on the tank needs to be a little sharper.
