01 7.3 Ltr fuel gage issue

[Lookn4trains]

Hello All
Recently my fuel gage on 01 super duty is acting up. The needle slowly rises to full a few minutes after the engine is running, one day it worked fine, had just above a half tank compared to my mileage counter like i figure. then next day the needle just rised to complete full tank. Any suggestions? Fuse? etc? help much appreciated.

I had problems with my fuel gauge a few months ago as well. Turned out my "fuel sending unit" was cracked. It left me stranded without fuel twice. Long story short it was an $800 repair.

appreciate the info. is the sending unit inside the tank? i will research more on that. i put a bowl under the engine today, drained quite a bit of fuel off, didnt really see anything bad in regards to contaminants or water, i have been using lucas oil additive for a couple of years now, hopefully that hasnt affected the fuel system. i have my daughters friend called he worked for ford as mechanic, gonna call him, if i find out any hard and fast info i will pass along. thanks again shooter

I was out in the woods this spring and I looked and saw my gauge slowly working its way up to full and it has been there ever sense. I figure the sending part in the tank is the problem. No way I will spend a bunch to get that fixed though. I just fill up every few days. Looking forward to replies

It's not that mine was an annoyance and never read right, it's that it would stop sending fuel to the engine because of the crack. It would usually stop picking up fuel when there was about 1/4 fuel left in the tank. Don't think this has happened to Lookn4trains yet, but if it does this could be a diagnosis.

Side note, Lookn4trains, I assume your into trains from the screen name lol. My Grandpa, Dad, and Uncle all work for Union Pacific. Grandpa used to be the foreman of the Houston yard, Uncle is head of IT, and dad used to lay track and stuff.

We're all gonna go see that unstoppable movie when it comes out!

Awesome shooter, i grew up in cincinnati, couldnt swing a dead cat without hitting a train when i was young, i have a lot of respect for the guys out there moving our commerce, takes a lot of intestinal fortitude to put up with the hours and time away from family. my last 3 years in navy was in great lakes prior to retirement, thats a whole lotta trains up there! Good friend of mine there is manager of track maintenance from Kenosha wisconsin to Chicago.

well, Josh99 gave me a good idea there, just monitor my fuel mileage, its been steady so i'll try that, both you guys have a great turkey day!
