Are you absolutely 100% positive that your vent line runs uphill from the top of the tank to the vent fitting?
Any sags, kinks, pinches or loops can fill with gas and give you a premature burp.
And I mean any. Just a tiny low spot can collect liquid, and if you've had to squeeze the hose at all (i.e. make it not round) to fit through anywhere or have pinched it with something, it's pretty much game over.
Same goes for the fill.
