Petrol pumps stopping when the tank is full

Random

How does it work? It's in the nossle of the bump I'm assuming and it stops on contact with further liquid indicating the tank is full - right?

Seen someone earlier at the garage and it didn't stop. It just splashed out at them. Looking at them the nossle seemed to be the whole way in too ?

Yeh seems to be the way they all work, ensures success when filling a cannister too! The person you saw may have just continued to override it.

Does the button usually make a loud clicking sound though and you have to actually release the handle and compress it again? (I was at the other side of the pump .. surely I'd have heard it?)

From another site:

When your petrol tank is full, and the nozzle is actually sitting in petrol rather than air, the pipe will suck this petrol through the pipe, rather than air, causing a drop in pressure that is detected by a valve, which shuts off the petrol supply.

I try to fill right up to the brim, but even then I've not had it splash out.

Sounds like a faulty pump then, but next time be a bit more nosey, inform them that you are a mod on boards.ie serving the people.

Danbo!

If you look into the end of the nozzle there is a smaller 'tube' opening at the bottom and if fuel goes into that it will sense fuel rather than air, and click the handle off. You have to release the handle and start pumping again to keep going.

Some people who stretch the pipe across their car, when they park on the wrong side, often put the pump in upside down and the tube thing isnt effective then. Also, if you have the pump in at the wrong angle/not far in enough, petrol can splash back into the tube and it will keep clicking off, even when the tank is empty. Just take out the pump and put it back in again, rather than shouting at the employee 'your ****ing pumps are ****in ****e'

Airlock followed by a blowback, the motoring equivalent of a belch.
Not anything to worry about unless it's repeated in polite company.

I've managed to do it before with an MR2 turbo. After playing petrol station roulette at 350km on a full tank I ignored the clicking/stopping mechanism and kept going... a bit of a spillage

Basically, if the op had asked the victim exactly what had happened, all would be clear. Not having a stab at mods.
