What are the common issues with the Kia Picanto's fuel system?

I have been experiencing some trouble with the fuel system of my Kia Picanto. The engine hesitates and sometimes stalls. I have changed the fuel filter, but the problem still persists. Any advice on what could be causing this issue?

It is possible that there is an issue with the fuel pump or the fuel injectors. I recommend getting them checked by a mechanic.

Another possible cause could be a clogged fuel line. Have a technician inspect and clean the fuel line to see if that resolves the issue.

Sometimes the problem could be due to a faulty fuel pressure regulator. Have it checked and replaced if necessary.
