A friend of mine worked at a gas station. After a customer would leave, my friend would drain the gas pump hose into a can. The next customer would unwittingly pay for filling up the pump hose before any gas got into his tank. My friend ended up working for the FBI. LOL
How old was that hose? There’s a check valve in it that shuts off the gas at the source so there’s no drainage. That advert that shows some guy draining what’s supposedly left in the hose into his tank. Next time you fill up and the pump shuts off, see if you can get anything but a few drips - maybe. It’s all due to the EPA regulations.
