Fuel Gauge Troubles

I'm researching 2005 F250 that appears to only have one problem. The fuel gauge has a history of trouble. The truck has been to the shop three times and came back working three times. The sending unit was replaced twice and was listed as having a rusted sending unit once. TSB 061311 was performed once. Once again the fuel gauge is not working properly. Upon fill up the gauge will not register more than about 1/2 tank. After driving it some it will register more, but never full. Is there a frequent problem with sending units? Any ideas as to a permanent fix for this problem? Thanks in advance for any input.

Heavy, the dealerships here in Tucson put me through many visits and bottles of Techron before finally replacing the instrument cluster...which immediately solved a problem that went on for almost 2 years. My problem was a little different, the fuel gauge would just drop to zero randomly, sometimes staying there, or not register full right after a fillup. But it sounds like all the other things have been replaced or dealt with, then look to the instrument panel.

danocross, thanks for the tip. The work will be on my nickel so I'm trying to avoid any trips to the dealer.

Fuel Low Light

I was getting close to empty and noticed the fuel pump light by the fuel guage. Never did run out having found a station selling Diesel, close though had between one to two gallons left when I filled up. The light never did go out or maybe it is alwas lit when the lights are on and I never noticed it before. Is there a method to get it to do so or do I have a problem. Mine is an 07. Didn't mean to hijack your thread. My problem fit the title.

I'm not sure. On other trucks I have, when the light stays on from a trouble code I can disconnect the battery & the loss of power will make the light go out. However, on the PSD it may not be as simple as that. The two battery combination has to be handled properly and a diagnostic tool may be required to turn off the light safely. On earlier model F150s, if you packed in the fuel on fillup, it would create a code/light that had to be cleared by Ford for a fee or by a diagnostic tool. Even with all that said I wouldn't think a low fuel light would require these kind of steps. I'm sure their are some really sharp folks somewhere on the site with the real answer.
