Inaccurate fuel guage

[Risky Bizness]

Our brand new 2024 F150 King Ranch with a 3.5 Liter had a fuel guage issue.The truck had 775 miles on it and the guage would read for example: 50 miles to empty when we got ready to go some where. When we checked it on the FORD Pass site, it would say 227 miles to empty. BUT, while driving the truck would read different saying it had 150 miles to empty.

It would change readings while driving it.

SO, I took it back to my dealer, and they hooked it up to their computer. Found it to be a sending unit. Ordered a new sending unit. Dropped the tank, and found out that there was also a cable with a corroded end on it, so ordered it and put it in. (Said it had no dilectric grease in it from the factory).

Total repair time was 2 1/2 days.

Truck seems to be working fine now. The tech said it had about a 1/2 tank of fuel. SO, we knew that the tank reading was wrong.

I didn't pick up my copy of the repair order, but I will. Was hoping to possibly have parts numbers on it for anyone to use it for future repairs.

It wouldn't be a Ford if the fuel gauge was accurate, now would it?



But I feel for you; wonky sending units are a pain.

I have a tank waiting to go back in my '97 Eldorado Touring Coupe (fuel pump went bad, actually, with integral sending unit), have already done the sending unit on my '72 Eldorado, the pump on my '98 Mustang, and still have to doit on my '99 Deville just over the sending unit.

And each and every one requiring the tank to be dropped.

(but were the Deville one year later, the pump could be pulled though a plate in the passenger compartment!0.

That reminds me of my '88 from back in the day that would only indicate the fuel level accurately once it was below 1/2 tank. Above that the needle would bounce around like crazy until it hit 1/2 then would be dead accurate, lol.

My 2020 Ranger would do the same thing on occasion. It was a late 2019 build so I chalked it up to 1st year model glitches. Haven't had many issues with the PB thankfully.

OP you can always go back to the dealer and ask them for a copy of the repair order so you have it for your records. They should be happy to print it out or even email it to you if you call your advisor about it.

YOu're right, I can get a copy. I just forgot to take it with me

It happens ?

I wish I could say that I have no idea why it would do that, but I've learned more about sending units than I ever wanted to know. (Start with: the fact that they exist!)

The cork floats on the pivot arm in the Ford Model A were more accurate than these things are.

My 2021 Lariat PB would show a quarter of a tank and when I would fill up it might take as much as 29gal. When it got to a quarter, I started looking for a gas station!
