Q: This means that when I open the filler cap air escapes and I can only get 24 ltrs of fuel in at a time even if the gauge is showing empty.
A: Is it sucking air in when you remove the filler cap? Perhaps the breather in the filler cap is blocked.
I have a problem with an Air Lock in the fuel tank on my Peugeot 206 has anyone else had the same problem.?
