Have not had problem with burping but I only use the lowest setting in the truck lanes. For me, a bigger problem is the foam that happens when diesel is pumped. After the foam shuts the automatic nozzle off, if I wait for the foam to go down I can squeeze another 4 gallons into the tank. That takes time due to foaming and it is not a nice thing to do if someone is waiting for the pump. All that said, that is why I like my 57 gallon replacement tank. Only rarely do I have to get fuel with the Monty hooked up.
