You're going to find the fuel tank pressure sensor (FTPS) located on the top of the fuel tank on the 2011 Ford F-150. It's part of the fuel pump assembly itself, which is itself part of the evaporative emissions system, and has the function of telling the engine control unit (ECU) about any leaks in the fuel system, or even a loose gas cap. Some signs the FTPS is going bad is going to be that Your fuel consumption increases noticeably (Your wallet feeling lighter will inform this) as well as having a lose of power or acceleration, and difficult starting Your vehicle --- many of these symptoms are shared with a failing crankshaft sensor, so You'll have a bit of investigating to do, to find out which is failing.
The ftps is not in the pump. I bought an assembly for my 13 and it is not there. It is located in the vapor line between the pump assembly and the charcoal canister.
