My Jetta will sputter and sometimes stall when the fuel gage reads below half tank. I have used the mileage counter to see if the gage is not correct, but the level seems true. I would also measure fuel quantity by the amount going in on a refuel. There is no engine light. Again it only happens when fuel level is below half tank. Very Puzzled and wondering if you have any ideas?

Replaced fuel filter and air filter

Hi vinman323,

Thank you for the donation.

From the symptom description I believe the fuel pump is the cause of the problem.

Check if the fuel pump strainer or connecting hoses are bad resulting in air being sucked into fuel lines when level drops below the 1/2 tank mark.

You can access the fyuel pump by folding the rear seat back forward and removing the fuel pump access hole cover.
