It sounds like a euphemism for something sexual, but Kim literally pumps Kanye's gas!

She was photographed filling up the Lambo over the weekend.

She not only bought him a $750,000 car, but she also puts gas in it!

Paparazzi snapped Kim and Kanye stopping at a gas station, where Kim hopped out to fill up Ye's Lamborghini Aventador LP 700-4—all while Kanye sat in the car.

Shouldn't the guy always pump the gas?
