Hi, I've seen lots of comments here about having trouble fueling up the 1000L fuel tank at a gas station. I've had trouble with this too, and found no resources online that would help solve my issue, so I figured I would make one.

You must make sure that the tail end of the fuel tank is close to the gas station pump. The tail end can be identified by the ladder, or by draining/filling with a gas can. It's very important you get this positioned closely to the pump.

Make sure you have a generator running if necessary, and then you should be able to fill the gasoline storage tank from the pump either by right clicking the fuel tank, or an option through vehicle mechanics.

Hope this helps.
