06 Mustang Garaged and Washed every week, Taken care of better than most of the Vehicles on the road with all preventive maintenance preformed ahead of schedule. Fuel Pump went out at 75,000 Miles. Surging and hesitation when reaching 2000 RPM. Error on dash along with Code P0460. Cluster display reads DTE FLI DTE ERR. Upon further research it is common for air bubbles to get sucked into the pump as well as contamination from High Sulfur cheap gas that Most gas stations sell.

Tried a bottle of Techron Gas treatment and did not help. Only solution was to replace the Pump. I Ended up buying a carter Pump with extended warranty. Getting locking ring off and removing old pump was easy. However getting the locking ring back on and in position was a PITA. However the pump is easily accessible by removing the back seat.

Guessing on the date and mileage but it was around it. 1st the sending Unit was going out, it would stop sending information to the fuel gauge and bring up an error on the display. Got the fuel pump replaced with one from the factory and it worked fine until 150,000 miles.

(guessing about the pump being the cause but everything is maintained and nothing looks dirty or in need of replacing)

When I go for a high speed acceleration or accelerating from a stop, the engine acts like it is not getting enough fuel. It will lose power and start to lunge. I have to let off the gas and slowly put my foot down and it will do better, but when you are in the passing lane and it happens with cars following, really dangerous.
