My fuel gauge on my 2006 Lincoln towncar reads E but the tank is F

trouble starting and pulling hills why worry hook up a fuel pressure gauge and see it read between 40 to 50 psi

Its inside the gas tank, so the tank has to be removed.

How do you know it is the fuel gauge? it could be the fuel level inside the fuel tank. Please give more information. You are not getting a reading? drop tank and the fuel lever is located ontop of the tank. put an ohm meter across the wires to see if the fuel lever is working. take the fuel lever out of the tank and inspect. Be carefull not to smoke or create a spark while working on the gas tank.

Fuel pumps outside the gas tank have nothing to do with fuel gauge readings. There is a fuel level sender unit inside the tank with a float which supplys variable ground circuit to the gauge. If you can find the wire to this unit, you can ground it to see if the gauge now goes to full. If so, sender unit in tank is bad, or has bad wiring/ground.

Bad fuel pump.
If so,have to remove the fuel tank,to replace pump

There is a TSB on high sulfur fuel usage, and how it impacts the fuel level resistance.
If you change fuel, it might start working again. The TSB is : ERRATIC FUEL GAUGE OPERATION TSB 08-2-9

ISSUE:
Some 2004-2008 F-150 and 2006-2008 Mark LT vehicles, built before 12/3/2007, may exhibit erratic fuel gauge operation or illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0460 or P0463, and/or Instrument Cluster Module DTC B1201. This may be caused by sulfur contamination in the fuel causing an open or high resistance in the fuel level sender.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

Install a new fuel level sender following the service procedure instruction sheet provided in the fuel sender kit.

its located inside the gas tank, you have to take the gas tank down

The fuel pump is inside the fuel tank on a 94 TOWN CAR. On the side of the tank facing the front of the car, up high on the tank there is a round plate with fuel lines and an electrical connection. The pump is attached to this plate.

Dont stick the pump nozzle all the way in. Just put it half way and it wont deactivate till you fill up. Good luck

If there is an access, it would be under the back seat,otherwise drop the tank. My friend has my manual for the towncars, and can't say for sure.
