fuel tank filler neck problems, Help!
I have an 86 f150 i300 longbed pickup. since i bought the truck i cant get gas to flow into the tank at a decent pace. i can only go about half speed and takes forever to put gas in the truck. I understand it maybe a vent problem? Im not sure but id like to just replace the entire neck strait into the tank. Ive tried taking the old filler neck out but it wont come out. is there some kind of crimp on the inner hose? can someone explain how to make a filler neck swap? thanks

Take the hose clamps loose going to the tank, take the 3 screws out of the bed around where you put the nozzle when filling, and then whole assembly will come out.
You will find a smaller pipe inside the larger rubber pipe. If you look down the filler hole you will see a spot where the smaller inside pipe is held in place, Make sure the smaller pipe is present and in the correct position in the holder in the neck.
The inner hose can get out of place, and cause the fuel from the station hose to splash back and cause the filler gun to cut off. It's purpose is to keep all the air coming out of the tank when you are filling, separated from the fuel going in. If this hose is missing or out of place, it can cause "gurgling" and pockets of air coming up out of the tank when filling will throw fuel backwards at the station gun and make it cut off.

I had to drop my rear tank to get the inner plastic tube back into it's "holder" in the tank.
I call it a holder for lack of a better word...
There is a "holder" on the tank side, and one on the filler neck that the plastic tubes slide into. This holds the tube up off the bottom of the filler neck and hose.
These plastic tubes can get damaged or dislodged from it's "holders" if someone siphons your gas.
The filler neck will slide into the filler hose, and the plastic tube will slide right into it's holder built into the neck without dropping the tank. The problem and why I had to drop the tank is the plastic tube came loose from the tank side and no way to reach that end with the tank in place.

Not replacing the filler, just moving it. I moved the fuel tank from the midship just inside the frame, to behind the rear axle, and am moving my fuel filler from the door on the side of the bed to behind the driver side taillight. I am afraid I may have to head to the local junkyard, as well, if I can't find an inexpensive replacement.
