Can’t fill up gas?

Usually, if someone has issues filling the tank, its because the vent valve is not open and the back pressure created when filling the tank, causes the fill pump to shut off.

Say wut? You lost me after the first sentence.

I do too.

When it comes to rental however, I fill it until I see the gas start to overflow. I prefer not to get gas close to the airport where it is more expensive.

Thanks for the response and sorry for the vagueness. Little more on it. The needle reads 3/4. On the pumps side it clicks at 10 gallons and I know that it needed more and figured it was the pump the first time it happened. I hit it again and gas spit out like it was overfilled.

When you are filling it up, fill it slowly. If you're having pressure issues, getting it to fill as fast as it can just builds up more pressure. Try putting it on the first notch while filling. (hope that makes sense)
