Nothing more annoying than a petrol pump that keeps stopping while refueling.

Is it the car or the gas station?

Both are possible.

And luckily there are solutions to address the problem.

One of the possible causes of this problem is that the car's fuel vent has become clogged or blocked.

In this case, fuel may rise in the car and cause the pump to shut off.

Some cars are extra sensitive to this because the development engineers have not thought carefully about the construction.

But often the problem is not due to the car, but to the operation of the pump.

Such a pump contains a valve that can interrupt the gasoline flow.

This is useful when your tank fills up and the system turns off automatically, but it turns out to be downright annoying when you have only just started refueling.

“Tilting the gun can also help or pull the gun back slightly from the pipe.

If that doesn't work, look for a gas station with slower-flowing pumps. ”

The cause is usually in the construction of the nozzle, which you insert into the tank opening. The nozzle has an outflow opening for the fuel and a small opening that sucks in air. It is important that air continues to flow through that opening. If the hole is covered, for example by the (too fast) rising level of petrol in the tank, a vacuum is created in the gun. That vacuum then sucks the shut-off valve down, stopping the fuel flow.

So if the pump keeps stalling over and over, something is usually blocking the small hole.

Often times, the culprit is simply fuel splashing back hard enough to temporarily block the hole, causing the shut-off valve to kick in.

In the case of smaller cars, this is often more likely due to a relatively short pipe between the filling opening and the tank.

A possible solution in this case: squeeze the nozzle less hard.

Tilting the gun can also help or pull the gun back slightly from the pipe.

If that doesn't work, find a gas station with slower-flowing pumps.

Overdue maintenance can also be the cause

Another possible cause has to do with overdue maintenance of the pump.

Sometimes the shelf life of the outflow opening of such a pump is no more than three years.

Service station operators can save money by not replacing it in time.

As a result, there is no longer a steady flow of fuel from the gun.

The deviation in the jet can, among other things, block the air hole in the nozzle due to unwanted turbulence.

Sometimes it also helps in that case to keep the nozzle upside down as much as possible during refueling, to turn it a little or to pull back a little further from the tank opening.
