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.
Replace it.
You can't. EPA and the government requires a gas tank to be replaced if it is leaking or cracked.
It is possible that the expansion tank on a boiler could have too much water and not enough air, causing leaking. To fix this problem, the tank should be adjusted to the right levels of each.
It probley would help putting the petrol tube into the tank
You can replace it. Or you get a plastic tank fix kit in AutoZone or Advance Auto Parts.
u send it to a mechanic or buy a new fuel injector or tank if its leaking
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, should only coast a few bucks at auto parts store.
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.
