Petrol splash back when refilling, Proton Saga 1st gen

[RigerZ]

So when I pumped petrol just now, I left the nozzle to pump automatically. When it stopped quite a lot of petrol splashed out from the filler hole.

1) I went to a petrol station which I dont normally go to; this is the first time happening. Petrol pumping too fast?

2) I noticed when looking down the filler hole there is a passage at the side where petrol will flow out and go back down the tank. What is this for?

3) I was refilling from 2/5 level. Some forums suggested an air pocket was forcing its way out?

Put it in the slowest flowing mode. My Persona flows super slow. U can hear them going down in the tube sound.

1) Flow was fast and the cut off was slow, probably due to the pump adjustment. However when pumping petrol best not to leave it unattended. You will never know when the pump can fail. I had at one time the pump did not cut so petrol was still flowing but luckily I was holding it

2) As far as i know the side passage is for air flow out when petrol goes in the main passage. When really full you can see even the petrol comes out from there but goes down the main passage again.

3) whether empty, 2/5 or near full no difference...

Yes it was, but my regular station is also Shell and I never had this happen

Still think is pump adjustment problem. Got back to your regular station.....

Faced the same issue a few times before. Shell stations as well. The cut off was definitely a little delayed, and as you remove the nozzle, quite a bit of petrol tends to spill out. Found this to only happen when filling 'full', If just stick to the RM50 per fill and gauge more accurately it never happens.
