Hello my people..
Pls I notice a huge pressure out anytime I open my tank cover to refill fuel.
But when parked over night I don't notice it.
And it's some how affecting my fuel gauge.
My fuel gauge will indicate low fuel ,but after I lease the pressure from the tank or when the car sits for some hours, the fuel gauge will return to it's original gauge..
The car is a vw touran 2.0 fsi engine.
Any help will be appreciated..

Do you understand the tank ventilation system. If you do then you can answer that question yourself. Read up about it
