Could be a failing fuel pump.
allow the unit to operate until the flame goes out
You have to remove the upper headers and it should be there toward the radiator and the fuel rail
No it will not. It will either be leaking or become clogged which will make the heater not produce any heat. it has nothing to do with fuel mileage.
Disconnect the battery. Drain the cooling system. Working in the passenger compartment remove the panels from under the dash and the steering column trim cover. Remove center console if you have one. Remove the heater outlet duct and glove box. Remove the heater core cover. Disconnect the heater hoses from the heater core. The hoses and clamps are in the engine compartment on the firewall. You may have to rotate the engine forward and remove fuel lines transmition dipstick tube and the plenum to gain access to these. Remove the heater core.
Your local auto parts store can sell you the tools needed to disconnect the heater hoses from the heater core. The tool comes in a set that is not expensive and is easy to use. You can also use the same tools for disconnecting fuel lines and AC connections.
When you say you've replaced everything you need to have heat, does that mean the engine thermostat? What you're descibing sounds a lot like a faulty engine thermostat. It could also be a collapsed or blocked hose between the engine and the heater core or possibly a blocked heater core. If there is quite a bit of foreign debris in the line that has blocked the heater core you might not be getting enough flow to keep the heater core warm. Try back-flushing the heater core. Remove both hoses, turn the heater to high (you might have to have the engine running if the heater controls run on the engine vacuum) and use the garden hose to make sure that you get good flow through the heater core. Don't allow more than about 15 psi through the heater core since much greater pressure can cause damage. As for fuel pump cutof switches, most are in the trunk either clearly marked on one side or the other or behind one of the side covers. If it isn't clearly marked, you may need to refer to the owners manual or contact a dealer.
Could the new fuel filter be installed backwards, therefore shutting off the fuel supply?
it very well could be your fuel pump relay warming up and shutting down. it ussually located on the fire wall.
passenger side pannel by floorboard / behind side pannel just below heater core.
check fuel sencer
If the fuel pump is causing a fuse to burn up on a Lincoln, perhaps it is because the fuel pump is not shutting off when it should. It could be running after the car is turned off.
