You can stop a leaking gas tank, by making a paste of soap on the hole of the gas tank.
If your vehicle is leaking fumes, then your gas tank needs to be fixed.
You can't. EPA and the government requires a gas tank to be replaced if it is leaking or cracked.
Replace it.
If its leaking from the gas tank directly, then yes...but it could also be leaking from the gas line or the engine or any of the connections in between.
Look inside the car above the fuel pump for an access panel. If there is none, you will have to drop the fuel tank to fix the leak if the leak is at the fuel pump. You need to determine exactly where it is leaking.
Your gas tank or one of your fuel lines is most likely leaking and your rear differential is probably leaking also. Your head gasket is located in the engine which is in the front of the car, not the rear. Take it to a mechanic because you DO NOT sound mechanically inclined enough to fix anything safely.
how much to fix a gas tank on a 93 grand cherokee?
How do you fix an airlock in a 2002 ford explorer gas tank.
it all depends on where its leaking from if its leaking from a hose then it could be a quick fix of 40 bucks but if its leaking from a gas tank then you might be able to empty it and clean it out and maybe put a spot of weld on it but if its too bad then you might have to spend upwards of 400 bucks or more on a new one and if its rusty then dont bother trying to fix it....
Replace it! Or there are places that will take your old tank (bare and dunk it in some type of teflon/rust proof coating. I'd go for the replacement.
