Gas Gauge i have a gas gauge problem as i'm driving my tanks says that i'm full of gas and then a friend said that i ran out of gas!!! what happenend??

Sounds like the float in the tank is faulty, or the gauge on the dash.
You should be able to unplug the circuit to the sending unit and check both components.

You probably have a ground wire not making contact to ground on the front tank sending unit. OR the sending unit itself inside the tank is faulty. Either way, when a gas guage goes to full all the time (empty or full), this indicates that NO ground is available for the sending unit.

replace front fuel pump because gauge is made into fuel pump and not serviceable. Or poor boy way of getting by would be fill front tank with gas reset mileage drive normal for a day. refill again with gas note gallons used and mileage driven for average miles per gallon. front tank should be around 17 gallons multiply by mile per gallon you figured

it's just either the gas gauge is being faulty

It may be the sending unit in the tank that needs replacing. Here's how you can check: Turn the key on and disconnect the sender unit at the gas tank. Ground the sender unit's wire with a jumper wire from the truck's harness to ground. Watch the gauge. If the gauge on the dash is good, grounding the sender wire will cause the gauge needle to react and should move to full. This would indicate a new sending unit is required. If the gauge doesn't move when the sender unit is grounded, the gauge is bad and needs replacing. Pull the instrument cluster out to replace the gas gauge. Likely any old ford gas gauge might work-back then, there were not so many production changes.

There is a fuel level sensor in the gas tank. If u are reading fuel in the take. Then its taking gas.

Float is off. Just try to put a full tank of gas in it and watch the gauge. Noone can siphone your tank BC there is a ball before the tank abling u not to siphoned.

hi it can really only be two things, first is the fuel sender on the pump inside the tank it could be stuffed or sticking causing a false reading, second it can also be a faulty fuel gauge on the dash.

Wont take gas and the gas gauge stays full? This question really doesn't make sense. But if you cant put anymore gas in the car and the gauge says full then you have a full tank of gas. If the gauge always says full even when the gas tank is not full then the sender unit is failing or the gauge itself.

sounds like you have a restriction in the fuel inlet pipe,( maybe air locking) also your tank sender unit neads replacing to fix you gauge fault, or it maybe that it has something that is not alowingf it to move freely inside the tank, have a good look inside when low on fuel. through the hole where the sender is fitted.
