Problems with gas guage
I recently purchased a 1995 F-150 its a beautiful truck. Well I am having problems with the gas guage, I can normally go about 220 per tank (dual tanks) but from about 150mi it is on empty. Whats going on with this, has this been brought up before? Any suggestions will be greatly appreciated.

It is quite common (perhaps std) for vehicles to read empty long before they really are. This does 3 things I can think of off hand.
1- it gives you a reserve to get to the gas station
2- it prevents you from really running out of gas and attempting to pump air, which could burn out the fuel pump.
and
3- if prevents you from filling the gas line with water. There is always ~some~ water in the gas you buy and since it floats on gas, its the last to get sucked up....
otherwise, yes i was amazed at the reserve myself when I had to run the tank dry to work on it just a few weeks ago myself!!

Wow, 220 per tank? I get like 140. Im *fixing* it tho 
.
Anyways, mine doesnt do that. Once its on 'E' it means EMPTY!. I thought that maybe it could stay on 'E' for a while... Nope. Good thing theres dual tanks.

Thanx for the advice papo Tim but I dont think if could be a reserve, no I ride motorcycles so I can see where you are getting at. but I dont think that it should be on E that long. I can see going a couple miles but not about 40.

Could be your fuel sending unit is going south for good. One of mine is and first it just starts bouncing and then it goes and sits on E for another 20 miles. You can either live with it or replace it. Worst part for replacing it is dropping the tank. The bit about water floating on gas is wrong. That was why in the NAVY we had water compensated fuel tanks that worked. Fuel is lighter than water (sheen on water when you spill).

I don't recall specifically, but it wasn't much. Here's the catch...while you have the tank down, its not a bad idea to do the fuel pump as well. That's where the big money is.
I'd give the local Ford dealership a call and see how much they can give it to you for, and ask if they know any auto parts stores that'll carry it. Dealerships are using expensive and they know it. I've gotten some of the best shopping advice from the guy behind the counter at my local Ford dealer.

'95 F150 Fuel gauge reading wrong
Since both tanks are acting the same way, I'd check the dash gauge itself.
Neither of my two tanks work all the time but they don't register identically on the gauge either.
Each affects the reading differently.
I read about checking the voltage reading from the sending units at the tank before dropping tank and replacing internal units.
I don't remember what the voltage reading are.
Maybe someone else has them available.

Mine does that too, but I take it to be normal. The guage works well, as in it doesn't jump around, I just have a bigger bottom half than top half. I've even got it figured out as to I have to be on the far side of the E tick before I worry about gettin gas. I can get around 350km per tank. Here's a question, for those of you with dual tanks, is your rear tank bigger than the front tank? Mine is, and I thought that was odd.
