Hi folks,

When my tank is full or almost full, it will make a loud noise like if
the tank(aluminium ???) was being pushed forward and then, retaking its
original shape. This noise sounds 2 times, usually when leaving (a few
hundred meters down the road) and when stopping the van ( a minute after
full stop.., engine not running)

Could it be related to a whining gas pump which suctioned too much or
not enough gas ?
