Normally, air flows through that tube while you’re filling and the gas keeps flowing as long as you hold down on the trigger. When that hole gets covered by gasoline (when your tank is full), a vacuum forms inside the nozzle and an automatic shutoff switch gets tripped, turning off the flow of gas with a thunk.
What are signs fuel pump is going bad?
A bad fuel pump may overheat and inadequately deliver gas to the engine, causing it to run hot and turn off while on the road. In this scenario, your vehicle may start back up after overheating and shutting down, only to do the same thing a half-hour later. This scenario is a common sign of a bad fuel pump.
Can you fix a fuel pump by yourself?

The equipment must accurately measure the amount of fuel pumped. Flow measurement is almost always done by a 4 stroke piston meter connected to an electronic encoder.

Hi There, This is likely related to your EVAP emissions system and something called a purge solenoid. The EVAP system prevents fuel vapors from the fuel tank from escaping into the atmosphere. The EVAP system collects and temporarily stores the fuel vapors in the charcoal canister.

In a nut shell: the numbers on the pump are an octane rating that measures the different volatility levels of gasoline. The numbers measure volatility in reverse of what you would expect. For example: A premium fuel with an octane rating of 93 is less volatile fuel, than a lesser grade fuel with an octane rating of 87.
What is the unit of gas?
Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).
