What do you do to get rid of gas from your mouth and stomach when siphoning your tank?

HF has a battery powered siphon hose. Hurricane Beryl knocked our power out of a week and the "kid" (30) got us one to put gas into the generator we had to get so not to lose out freezer. Works slicker than cat chit and IF he bought 4 of them, they must be cheap! I will add some hose and use it top drain and add gas to my old car gas tanks.
