Peugeot Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is XXXXX XXXXX I will try help you with this.
This is caused by either a blocked fuel tank vent or a restriction lower down in the filler neck.
Either way you will need to get under the vehicle to see if you can find what is blocking the vent or remove the filler neck to see if anything has been pushed down inside it.
