    Some more info: can see the leak coming down at the LHS while the engine running even when the tank is nearly empty, could it be other than tank leak problem?

    Megadeth_600 is right, the plastic tank is not at fault. Based on his input I opened the plate with 3 screws. I do not notice any leak until I start the engine. There you are I can see petrol start leaking from the connection of the outlet hose. I tried to tighten the securing clip and it snap right away. Changed to a new clip and restart the engine, and that's it no more leak. Thank Megadeth_600 and to Ajkill.Finally manage to solve my problem within minutes and without the hassle of removing ha gas tank. Great!

REMOVAL & INSTALLATION
Always ground yourself to the vehicle's chassis to prevent sparks while working on or around the fuel tank.

  1. Disconnect the negative battery cable.
  2. Remove the access panel under the rear seat or in the luggage compartment.
  3. Disconnect the gauge sending unit wiring and hoses.
  4. Raise and safely support the vehicle.
  5. Drain the fuel tank into an approved container.
  6. On Cabriolet models, remove the right rear inner fender and disconnect the breather hose from the filler. Remove, but do not disconnect the gravity valve.
  7. Detach the fuel pump bracket from the body.
  8. Lower the pump enough to disconnect the fuel hoses from the tank.
  9. On Cabriolet models, the rear axle must be dropped out of the way as follows:
    1. Disconnect the brake hydraulic hoses at both sides of the rear axle.
    2. Detach the rear axle from the body on both sides and let it hang on the parking brake cables.
  10. Unhook the muffler supports and pull the large hose from the filler neck.
  11. Support the tank, loosen the straps and carefully lower the tank out of the vehicle.
To install:
  1. If a new tank is being installed, glue new foam strips to the tank in the same location as the old ones.
  2. Position the tank and secure it with the straps.
  3. Connect the wiring and hoses to the sending unit.
  4. Attach the fuel pump bracket to the body.
  5. On Cabriolet models, install the rear axle, connect the hydraulic lines and bleed the brakes.
  6. Install the access panel once all electrical connections have been made.
  7. Connect the negative battery cable.
  8. Fill the tank with fuel and check for leaks.

Check the tank by the trunk. In other words, lift the floor in ur trunk, the tank cover (about 6 inches in diameter and same color as the car) should be right there under a plate with three screws. Open that with a phillips head screwdriver (star) and check if u see gas there, maybe the gasket (more like an o ring) is no more good. U will have to unscrew that big white plastic bolt there but check to make sure the two gas lines are snug and secure in their place first.

VW's have plastic gas tanks, therefore not rusted or punctured( highly unlikely)

If this doesn't help, lemme know and ill tell u how to remove the gas tank.

Good luck.

When filling up the gas tank of my 1998 Pontiac Grand Prix SE, it releabsed a few cups of gasoline from somewhere at the bottom of the car. I'm not sure why??? It hasn't leaked since.


Both the fuel pump and gas gage sending units are located inside the tank. They are accessed by a plate and gasket on top of the fuel tank.
If the gasket leaks or the hoses leading to the vent leak, your condition would happen. Unfortunately to confirm the tank would have to be dropped(removed) which requires all the fuel to be removed first. Not a pleasant nor easy task.

Ford freestyle smell like gas inside


Could be a small gas leak in one of the gas lines or even a leak on top of the gas tank and yes could even be a leak where the fuel pump goes in the top of the tank. Quite often the leak is on the tank top out of sight and it smells of gas even if you have a slight leak.

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.

Theres a gas tank leak comining from the top of the gas tank. what could this be /


Not knowing your milage or what part of the country you live in if they use salt on the roads. The leak is coming form the three fuel lines going into the gas tank and fuel pump. The fuel pump is inside of the gas tank secured by a large slip ring seal. From the years gone by these lines rust and since they are under pressure they will leak through. You will have to drop your gas tank to get to this. This is a ugly all day expensive job. Replace the fuel pump which comes with the new seal and fuel lines assembly. I could sit here and tell you the step by step procedure but that will take hours. The very best thing you can do is buy a Haynes repair manual for your car and year at any auto parts store @ Advanced, Autozone. Read the step by step in the manual. I have used these for 40 years with all my vehicles and saved tons of cash in labor costs. Be prepared to replace the gas tank straps and additional fuel lines depending on how bad the rust is.
Good luck and thanks for your question and I hope my suggestions help. Don't forget to rate me.

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.

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.
