Gas gauge issue

Gas gauge issue
Hi. My gauge was dead when I bought truck. Tried everthing and then repalced the fuel pump/sender. Gauge works. Sort of. I have a 2000 XLT. Its supposed to have a 20 gal gas tank. When I fill it goes fill and not much going on wrong for the most part. But from empty on the gauge when I fill it the pump says its full when I put twelve gallons in. So tank registering empty with gallon in it. Any ideas?

Did you check the float range on the new one?
3rd party(not Motorcraft) pumps are often spring loaded so are made to fit more than one size gas tank so sender/float needs to be set for YOUR size tank
Float arm may need to be bent down a bit so its closer to the bottom of the tank when at the end of its travel in the sender part
Generally you should have about 2 gallons left when gauge is on Empty and engine may stumble when cornering hard, pump gets uncovered and sucks in air for a moment
Extended cabs have 20gal, and regular cab Long Beds
Regular cabs usually had 17gal
If it takes more than 30 miles to come off of Full then float arm needs to be adjusted most likely
If you stand the pump up on a flat surface the float should be about 1 to 2 inches above the surface, that's YOUR choice on how much reserve you want, lol

Have a question for you RonD. I assumed that if the pump were as you said and needed adjustment on the arm that it would only be an issue with the gauge. I did not think it would cause the truck to run out of gas by stopping the fuel pump when it was at the low setting. Because it is starting to look like the the gauge is accuarte. Makes me wonder if I do have a 20 gallon tank. Because it seems like when it hits E it will run out of gas shortly after.

Not sure I understand the question
There is no electrical connection between the fuel pump and sender/float, each has its own 2 wires, they don't even share a ground
There is no adjustment for the pump, it always sits at the lowest point in the tank
The sender for the gauge has a metal arm with a float on the end, the float does what it sounds like, it floats on top of the gasoline in the tank, this causes the sender OHMS to change based on the angle of the metal rod attached to the float
16 ohms = Empty
160 ohms = Full
You can bend the metal rod/arm to suit your needs, Empty is usually most peoples concern, lol, for obvious reasons
3rd party fuel pump assembly senders are not always set up properly for specific models, i.e. Rangers, most Ford vehicles use a 12volt fuel pump and 16/160 ohm senders, so 3rd party can be used in several models
If your Ranger ran out of gas when gauge was not quite on Empty, or was not on Empty for long, then sender/float is out of adjustment, but at least you know to not go below 1/8 of a tank again

I'm confused too. Inhad thought thenarm was out of adjustment on new pump. Old sender didn't work and had no gas reading. But from empty on new pump reading the truck doesn't take 20 gallons to get full. I am afraid to run iut of gas to rest it but I have run out becausenI assumed I had 8 gallons of fuel left when it hits E on my gauge. Assuming the arm needed adjusting. But I ran out and Imita starting to look like there isn't much has in there when its on E.

Gauge
Guge does come off full pretty quickly. But it gets to get and the light comes on "check gauge". At that point I filled it up and it took 13.7 gallons. But that can't be right. I have a 2000 extended cab XLT. Should have a 20 gallon tank. I was riding further on that "check gauge light withe the needle on low but I ran out and don't want to tey that again.

Has anybody just replaced a float on a 2005 Ranger XLT 4x4 with the 4.0? I suspect from what I have read that my float is cracked and loaded with fuel causing my gauge to read empty. If so any advise or a good part number to buy a new float?
Thanks in advance.
my email is cdesjardn1@gmail if it's easier to send it that way.
Also, anything about 2005 I should pay attention to? bought this for my middle kid to learn how to drive stick. Thanks in advance for any help.

I could be wrong about this. But on my 2000 I pulled a float from a junkyard 2000 because earlier years had posts of floats full of fuel. Guess what? On the 2000 the float is solid. Its probably your sender
