Fuel gauge not working past year, it kept giving false readings
I recently had bad gas smell in my car. After inspection, I found a pin hole in the plastic part of the dealer manufactured fuel line topside. It was hard to see but, it kept squirting fuel out after the vehicle was shut off. I had the line replaced by the dealer. Upon receiving my car from the dealer I noticed that my gas guage was functioning correctly again. It's been a week and still good. Question; Is the fuel system a vacuum pressurized system and since the line was compromised with a hole would that have kept the fuel guage from reading the fuel level correctly?

Dont believe so as you have been driving it for a year and its only recently leaked so no link there.More likely the mechanic who fixed your car got it going again.Loose terminal, bad earth or some thing small enough to fix as a service/good will without charging you for it.

Check that there are no holes in the float. If the fuel is getting into the float, it will give a false reading. Another thing is to check the ground on the float sensor. If it's not connected tightly, it will create a false reading too.
Depending on the Year of Expedition there was a recall for Gas tank straps. Those units having shields for the Off-road package kept the gas tanks from falling off the vehicle. For units without the shields, the tank could hang from the remaining strap which would put all the pressure on the remaining strap. The repair for the strap is free under Warranty. There are other parts which may fail. The main line to the fuel pump can rust. Any metal component up to the fuel injectors can likewise fail. There is also a system for the Emissions and the vapors can leak if the hoses have pin holes. A device called a "smoke test machine" is needed to detect these leaks. This is a possibility since you see no fuel puddles under your vehicle. A tiny fuel leak can seep and evaporate while the vehicle is in motion. I would call in the vehicle VIN# and see if your particular unit has been recalled for the straps. An inspection under the vehicle would be useful. After that, do a "smoke test".
There is a fuel gauge sensor in your fuel tank. If the sensor is out of place, it will not read the amount of gas in your tank correctly if it is out of place. This is a fixable job, but I recommend a ceritfied mechanic. Hope this helps! Please give 4 thumbs up!
The Fuel level FLOAT, in the tank is defective. Possible that it "holed", and has sunk to the bottom of the tank. To check, separate the harness plug to the Tank sender unit, and ground the supply to a suitable place on the frame. The dash gauge should record "Full", therefore the sender unit is suspect. regards. DT
Hello graytape, was the fuel gauge and low fuel light working and then one day just stopped working?, if so, you have probably blown a fuse and you should be able to locate what fuse and where it's located in the owner's manual.
If you recently got the vehicle and then you found out that the gas gauge and low fuel light doesn't work then that is something completely different.
without knowing the year of the vehicle I can only give you an educated guess.
Many vehicles have a float in the gas tank and this float is directly linked to what you see on the gas gauge. However, after a number of years the floats get saturated from the fuel and become heavy, heavy enough to where they don't float anymore. That is one of the most common causes of the fuel gauge not working.
The sensor that activates the low fuel warning light may be independent of the fuel gauge and the fuel in the tank isn't low enough to turn it on. Your tank has to be very low to activate the low fuel warning light.
Hello. Before getting involved in real repairs, dump a bottle of fuel injector cleaner in your fuel tank. It may clean your sending units enough to get them working again. The chances of success are only about 50%, but the cost is very low. Redline, Chevron, and others make good fuel injection cleaner.
You could possibly have air in your cooling system. If the dash gauge temperature sensor does not have coolant flowing past it, it will give a false temperature reading while your engine is actually overheating. If you recently drained and refilled your cooling system, you might need to bleed the air out of that system. If you didn't drain it recently, you might have a leak that's letting out coolant and letting in air.
my wife kept smelling raw gas but i couldn't. problem was a tiny hole in the FRONT of the gas tank. i then remembered hitting something in the road some time back. insurance replaced it with a used tank. this hole was visible as a wet area around the hole. the hole it's self was so small you could hardly see it.just a possibility.......ray
