DESCRIBE WERE THE FUEL PUMP IS LOCATED AND WHAT COLOUR AND SHAPE IT LOOKS LIKE FOR AN FORD FD Ltd 1983 6 cylinder

maybe 4 gallons is not enough in that big tank I would consider say another 20 gallons before I looked for more problems

Look for a elbow shaped tube on the top of the valve cover.
It looks like only a connector but inside of the elbow is the valve.
The elbow shaped PVC valve tends to clog faster than ones that are designed to be straight.

The 83 still used a carb and mechanical fuel pump I believe.
And the fuel pump is probably bad.
Check the oil and make sure it is not over filled with gasoline.
Take the fuel line off the carb, and see if the pump squirts when engine cranked.
Open the gas cap as well, so make sure a stuck purge valve is not holding the gas back.

Check for voltage at coil and also for spark leaking at coil to terminal. Maybe ignition fuse?

check the coil and for spark

you could have sludge in your gas tank which moves around and clogs your fuel pump. it happens alot in older vehicles.

BACK IN 1985 FORD MOUNTED FUEL PUMP IN 3 LOCATION.IT HAD MECHANICAL FUEL PUMP BOLTED ON THE ENGINE.ELECTRIC EXTERNAL FUEL PUMP.ON THE OUTSIDE OF FUEL TANK.THE INTERNAL ELECTRIC FUEL PUMP.ON THE INSIDE OF FUEL TANK.

at rear near the fuel tank, round can shaped filter.

Actually, even in 1982 Ford produced fuel injected vehicles. They used electric pumps, rarther than the mechanical one r_clark is referring to. So, the question is, is it fuel injected, or is it carbureted? If it's carubureted, r_clark is correct. The timing cover is on the front of the motor as you are facing it. If you look behind the large main pulley at the bottom front of the motor you'll see an oval shaped cover. That metal oval cover is the timing chain cover. Look to the left of it, still facing the front of the engine and you should see the fuel pump if you have a carbureter. If, on the other hand you have throttle body injection, the Ford F250 uses two electric fuel pumps. One is a low pressure pump which is inside the fuel tank, the other is the high pressure pump which is mounted on the vehicle's frame. That one will normally be located just in front of the tank on the inside rail of the frame assembly. It looks like a large cylinder mounted on a bracket with wires going to it. If you see a cylinder that just has a fuel input and output line with no wires, that is an inline filter, not the pump.

Also, keep in mind if you are asking about the pump because you are not getting fuel, you might want to check to see if you have a large canister style filter down there on the frame. If that's plugged, you won't get adequate fuel!
