So you have him drain his tank, and disconnect the line from the tank to the filter, or you do it and charge for it too and then you rinse it out for him. You can use a shop vac on the discharge side to blow out the residual water.
You make it clear that he is the one to confirm the tank is dry before refueling and off you go.
Quick and easy money.
