Answers 1 & 2 pretty much nailed it, you have a hole in the tank or well that's pretty much it. There are no outside lines that close to a near empty tank and your fuel pump is either midway on the side ot mounted into the top, so I'd place my money on either a hole under the tank strap or a seam on the tank gave way.

Hole in tank. Most likely a hole right in the bottom. If you can't find it right away, it could be under the straps that hold it on. Can you see anything wet near the bottom of the tank? Does it leak while its running, not running, or both?

Surely you can see the fuel on the outside of the
fuel tank or a rusted fuel tube under it

You should be able to find that issue in 10 minutes
IF you get under it

That is only 2 gallons added at a time

Wouldn't you think the fuel tank is the issue,if
it leaks without the motor running

Now you also know we can not guess from here

SOURCE: gas gauge

The float that moves the gas hand is possibly stuck in the tank. If there's isn't an access hole in the rear of the vehicle you'll have to drop the tank. Unless it becomes free on it's own. Hope this is helpful. Please rate. Thanks

SOURCE: Fuel Leak

VERY carefully. This is a dangerous job due to the explosive nature of gasoline. I would recommend doing it outside on a breezy day (to dissipate fumes that are highly explosive). I would also recommend running the tank down low before. You can purchase rubber fuel line to replace it. Slide the rubber line over the metal line where it's solid, clamp it, and do the same for the other end. Be Careful!!! Use plastic zip ties to support the hose and prevent it from hanging down.

SOURCE: gas gauge reads empty and low fuel with 10 to 20 gallons of fuel

Other than replacing the sensor which is part of the fuel pump assembly inside the tank, you may have loose or corroded connections in the wiring just outside of the fuel pump/sensor position on the tank. These connections are exposed to water/salt conditions from road spray. May the force be with you!

2002 Lincoln ls has a gas leak when I go to the gas station and put 15$ or more gas starts rushing out not all of it maybe 5$ worth which is enough and as I drive it today I see a small leak

I can see your picture that you posted. Each tank can usually only leak from a few places. The filler tube, the overfill tube, the fuel line going in, the fuel line going out, or a seam in a metal tank. Also, seeing as how A lot of pumps are made of plastic, it could be leaking from there also. As I stated before there is also a rubber O-ring between the pump and the tank which could also leak. Other than that, that is it, unless there is a hole in the tank. Please be cautious

Can i put coolent leak repair through the reservoir tank as we cant find the radiator cap in this VW Bora v5

It depends on the type of leak sealer and how much flow there is through the degassing tank. If the leak sealer is a solid it should not be put in the tank and if it is a liquid with lots of solids that must be vigorously shaken it would be better if it isn't added to the tank unless the coolant level is first lowered to effectively empty the tank so the leak sealer will enter the main cooling system almost immediately.

In almost every case the best results are usually obtained by adding directly to the radiator and in the absence of a radiator cap or a filler on the engine, disconnecting the top radiator hose and adding the leak sealer there before reconnecting and topping up with the saved coolant will ensure maximum efficiency of the product.

My 1988 dodge ram custom 50 I think is having fuel pump problems. It chokes going mainly up hills. or could it be the fuel filter?

There are fuel lines inside the gas tank. Over time they can rust causing them to break or leak. You have one of two options, first you can pull the tank and replace the line. The second option is to keep the gas tank fuel level above the leak. And the fact that this happens mainly when going up a hill, suggests the leak is lower in the tank. All the gas shifts to the rear of the tank and exposes the leak. NOTE: The leak is probably just above the level you usually keep the tank filled to. So if you keep it at 1/4 that's where you'll find it etc....

worth checking the fuel tank for holes or there might be some fuel delivery pipes leaking badly. Or it might be an O2 sensor not giving correct signal to ecu thus consuming so much fuel.

2000 ford windstar problem with gas mileage

Start the car with the hood open. Check the engine compartment as well as the fuel line from the fuel tank to the engine compartment. If there is a leak you will find it. Remember gasoline will evaporate quickly when there is air movement so watch carefully to make sure you don't look over the leak.

My 95 accord waste alot of gas but can't seem to find a leak in the gas tank either my exaust is too big. i can fill it at half a tank and if i drive a mile it will be at empty

You certainly have a leak then. The engine could not cope with that amount of fuel. If the tank is not leaking, check all the flexible hoses and connections, especially those on the pressure side of the fuel pump.

Monster fuel leak

if the gas is leaking from the top of the tank, 10 to 1 it's either the fuel line, or the top part of the sending unit which is probably made of plastic, is cracked where the fuel line connects to.The tank should be empty or near it, easier to drop, loosen the tank strap bolts towards the front, then remove the rear ones one at a time, as you take the last rear bolt out, the tank should drop a little. Becarful of the wire connection and fuel line, drop it slowly enough to reach in and disconnect them.If the unit has a plastic hose connection, it needs replacing. good luck.
