Hi Christian: When this happens at 1/4 tank, check the hose that goes between the fuel pump and the fuel pickup strainer, inside the tank. Look for a cracked hose just below where it is secured to the pump. This happened to me... at 1/4 tank the fuel level was below the crack in the hose, and I began to suck air into the hose, causing the car to lurch, especially at turns and accelleration.
