Question gas guage

Nearly each time I start my truck I get different readings and the tripometer miles to empty changes as well. Any other experience on this or advice on what to look for?

truck info if it matters:
99 250 v10 cc 4x4

I also have a 99 v-10, the only difference I have seen is when I park either up a hill or down a hill. The gauge sending unit is apparently in the rear of the tank. Say if I have a 1/8th of a tank and I park up a hill it will show over a 1/4-1/2 when I start it the next time. Or it will show way empty if I park down hill. Maybe not your issue but thought I would put in my $.02.

Good luck

had the same problem on my 04 F-250, V-10, Ford replaced the fuel sending unit under warranty. I haven't had the problem again.

brad99sd mine does that as well but now does the other weird stuff too. Is the fuel sending unit an easy fix?

Duckhacker,

To be honest, I'm not too sure where it is on the tank or if it's easily replaceble. I can check and see if it is in my hayes manual or not for you. I have just learned to get used to it, it has done it since new and I have 107K on it now and it's not that often I park on a hill. I kind of assumed it is normal since it makes sense that the sending unit must be in the rear of the tank(it's consistant). I will try to remember to check for you.

wrong fuel level

just bought my 01 250 and it has the same problem in reading the wrong amount. When I fill the tank it only shows 3/4 full and thats on flat ground. took it to the shop to have the sending unit replaced under warranty. the shop told me that the stock sending unit is **** and that even the new 05's off the dealership have the same problem. easy fix though just drop the gas tank and replace it witha new one.

Gees,

I hope mine never takes a big S**T!! I have been lucky so far, mine only depends on where I park. I am assuming it is probably right near the fuel pump and the exit and return lines on top the tank. I keep forgetting to look in my manual, sorry.

the gas tank is on the driver side of the bed with the sending unit towards the the rear of the tank. when replacing the sender you have to take off the fuel pump as it is all one assembly unlike my mustang that has a seperate sending unit and fuel pump assembly

I have the same problem as 1badSD...When I fill my tank on my '02 F250, I only get a reading of 3/4 of a tank...quite annoying!!

Do I have to drop the tank to get to the sending unit? Is the sending unit an expensive item?

Sending Unit

Unfortunately you have to drop the gas tank. Just make sure you are on empty to make things easier as the sending unit is on top off the fuel tank. Pretty easy just put a jack underneath the tank, loosen the straps, drop the tank, dissconnect the fuel line (need fuel line dissconnect tool), swap the sender, and put everthing back together. Looks like you have to get the sending from ford as I couldn't find it on any of the parts dealers websites. Hope this helps.
