You need to invest in some jack stands or take it to a mechanic shop to get it off the ground so you can work on it.

Gas seems to be coming from the top of plastic gas tank and running down the left side of the tank and dripping on the ground


I know it sounds a bit difficult but fuel leaking is serious danger so with this id siphon tank dry (don't use a drill pump ) and undo fasteners and hoses/wires that hold it too truck , lowering it to ground , a carefull inspection of approx. area of leak will tell the problem , your looking for cracks in plastic or rubber hoses , these might be very small and fine look closely
if cracks are in the tank , unless you know someone with a ultrasonic welder id replace the tank

The hose is on the side of the gas cap and it runs down to the bottom of the quarter panel. When I filled the gas tank up, gas comes out of this hose. We just had the fuel pump replaced. Its not leaking...


There are normally two hose lines from the fuel filler that run to the tank. The larger one carries the fuel from the nozzle to the tank. The smaller one is a vent hose that allows vapors to leave the top of the tank while filling. These vapors come back to the nozzle area and can be vented and/or collected by the nozzle depending upon air pollution standards in your area. If your second hose is running to the bottom of the quarter panel, it is probably the vent hose that may not have been reconnected at the top of the tank when the fuel pump was replaced. The fuel running down there is from kickback fuel at the time the pump shuts off. The real problem is that the vent line is open on top of the tank and when the tank is full, that can allow vapors and fuel to escape out of there and it could contact hot exhaust areas - a major fire or explosion hazard. Have this inspected and repaired IMMEDIATELY.

Why does my svt contour gas tank overflow into the parking lot when filling up.


There are two hoses running from the filler neck. Either of them could be leaking from the top. There is also a seal on the top of the tank where the fuel pump is that can leak. If your car leaks the whole time you are putting fuel in, I would suspect the hoses. If it only leaks when you get it full, then check the seal on the top of the tank. The top of the tank can be seen without dropping the tank. Remove your back seat and you will see a cover over the fuel pump. Remove that cover and you can see the top of the tank.

Try a fuel filter:
Fuel Filter REMOVAL & INSTALLATION The in-line fuel filter is located in the engine compartment between the fuel tank and the fuel rail.
  1. Properly relieve the fuel system pressure.
  2. Disconnect the negative battery cable.
  3. Position a suitable container below the fuel filter to collect any excess fuel that may leak from the filter and lines. CAUTION
    Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.
  4. Remove the retaining clip from the fuel filter upper hose.
  5. Disconnect the upper hose from the fuel filter and drain any excess fuel into the container. Plug the hose.
  6. Raise and safely support the vehicle.
  7. Remove the retaining clip from the fuel filter lower hose.
  8. Disconnect the lower hose from the fuel filter and drain any excess fuel into the container. Plug the hose.
  9. Lower the vehicle.
  10. Unfasten the filter retaining clamp screw and remove the fuel filter. Fig. 1: The fuel filter is located in the engine compartment, between the fuel tank and fuel rail — 1.9L engine's underside shown 90981p47.jpg

I have a 1991 Toyota Corolla and I don't know what is wrong with my fuel hose, it leaks when I make a right, and when I fill the tank to a point. And I can't locate the problem, all there is, is a stench...


you need to get your car to a car shop so they can put it on a lift to see what is wrong. fuel leak can be very dangerous.
there is a fuel pump gasket on the top of the tank
there is a filler hose goes to the side of the tank
there are a pressure hose and a return hose go to the top of the tank
there are evaporation hoses on top of the tank as well.
rubber hoses are getting old and crack easily
so there are many possibiltities that can cause leak

Fuel tank leaking how to solve problem gas is not pouring out but is seeping through bottom of tank There is fuel leaking from the top of the tank, is it a fuel overflow release or is the seal on the fuel...


If your gas tank is cracked or has a hole in it, you have to drain the tank, remove the gas tank and replace it, or have it repaired (if possible). If the gas tank is just leaking from the top and dripping along the side and to the bottom, you will still have to empty the gas tank, and remove it to get a good look at the condition of the gasket. It is not uncommon for these gaskets to become cracked or fragile over time because of the harsh chemicals and cleaning agents used in unleaded gas. If you do decide to have the gas tank removed, I would recommend replacing the fuel pump and fuel filter if your car has high mileage. Please rate this response if you found this helpful.

Gas tank filler hose on Ford E Super Duty Motor Home


Look again into the fuel filler there should be a metal hose which is where the tank gets it's air from, ensure when your filling up your not pushing the fuel filler gun fully home when filling up, suggest you don't fill the tank right up to the very top as your correct it's a big job & you will need parts before you take the tank off. http://passionford.com/forum
