SOURCE: 2003 F150 need to know
In a Ford CCOT system, the orifice tube must be located in the liquid
line between the outlet of the condenser and the inlet of the
evaporator. On the 02 F-series with V8, it is located in the
evaporator inlet port, a pretty common point for Ford to put it. You
have to remove the inlet line and then you can access the orifice tube. Check this diagram like a reference guide (click image for zoom)...
This is for an 2001 F-150... the orifice tube is located in the bottom line from the evaporator to the bottom line to the condenser (click image for zoom)...
Hope this helps.

The combination fuel filter and fuel pressure regulator is used on all engines. It is located on the top of the fuel pump module. A separate frame mounted fuel filter is not used with any engine.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for extended service. They do not require normal scheduled maintenance.

SOURCE: location of oxygen sensor
I believe you may have three (3) O2 sensor, (2) of the sensor is on ether side of the exhaust down pipe and some times called up stream O2 sensor, the third O2 sensor know to some as the down stream O2 and is after the Catalytic converter.
The up stream O2 monitors the left and right side banks and sends signals to the ECM to make the adjustments to the injectors to keep the proper air/fuel ratio.
The down stream O2 monitors the catalytic converter and sends signal to the ECM if the catalytic converter has gone bad.
Good luck and hope this helps. If you get it scanned at Auto Zone, they should be able to let you know which O2 has gone bad so as to not change all three. You could always check the wire harness to the down stream O2 for corrosion. Keep me posted
