Over time, a gas tank may begin to corrode and fail. When this happens, gas may leak from the vehicle, having an effect on fuel economy, and potentially leading to a dangerous fire or explosion. If gasoline is leaking from the gas tank, you should be able to notice the leak underneath the rear of the vehicle accompanied by a noticeable smell. It is important to inspect the kind of fluid leaking to ensure that it is gasoline. Gasoline may also leak from fuel lines and may require a different repair than a leak from the fuel tank. Finding the origin of the leak will help you and the mechanic determine what repairs will need to be made.

How this system works:

The gas tank is a reservoir for gasoline used to power the combustion engine in an automobile. Gasoline is filled from outside the vehicle, down a filler neck, and into the tank. Tank size and material varies based upon the size and make of the vehicle. Gas tanks are typically made of metal or plastic and may be built with the fuel pump inside the tank. Whether or not the fuel pump inside the tank or not, fuel is pumped from the tank to the engine where it mixes with air and is burned. A leak in the fuel tank may be dangerous and cause flammable vapors to escape the tank.

Common reasons for this to happen:

  • Corroded/Leaking Gas Tank: Over time, gas tanks may corrode and start leaking. In areas where there is a lot of snow and salt, corrosion may be more prevalent and more rapid. Depending on the location of the leak (e.g. if it is on a seam) there may be an increased risk that the leak will become worse if not dealt with.

  • Punctured Gas Tank: Even though gas tanks are typically made from sturdy materials, it is possible that a gas tank could be punctured. Punctures are more serious and may require the entire tank to be replaced.

What to expect:

A top-rated mobile mechanic will come to your home or office to determine the origin of the leak and what repairs will necessary. The mechanic will then provide a detailed inspection report outlining the nature and cause of the leak and the cost of any repairs that need to be made.

How it's done:

A mechanic will first inspect the ground underneath the gas tank to see if gasoline has pooled under the tank. The mechanic should then inspect the tank itself to identify the source of the leak. He or she should then determine if the original tank can be repaired or if it needs to be replaced completely. If the tank needs to be replaced, the mechanic will first drain the old tank. He or she should then disconnect the original fuel lines, inspecting them to see if they if they need to be replaced. The mechanic will then remove the straps that hold the tank and drop it. The mechanic should install the new tank ensuring that all the appropriate parts are reconnected. He or she will then add fuel to the tank and start the vehicle to make sure the fuel system is working properly.

How important is this service?

Any gas leak can become extremely dangerous if not dealt with. Besides the worsening fuel economy, your vehicle may also be susceptible to fire or an explosion. A mechanic may be able to repair the gas tank without having to fully replace it. If you notice a gas smell or gas pooling underneath the gas tank you should let a mechanic inspect your vehicle. Having a mechanic inspect your gas tank can help recover lost gas mileage and keep your passengers safe. Gas leaks will only become worse over time and should be dealt with immediately.

BMW 740i V8-4.4L - Starter - Beaverton, Oregon
Andrew came out last week and troubleshot my car in the garage and said it was the starter motor. I had suspected it was the starter motor but wasn't quite sure so it was good to get a verification. I have to admit, I was kinda skeptical about this home mechanic thing so I was taking a wait and see attitude until after he came back for the repairs. Both times, Andrew showed up early..which is fine by me. Today, when he came back, he went straight to work installing the new starter motor and changed the oil. Car fired right up so I was happy and I've started it a few more times and it is working well and I don't see any oil leaking. If there was a half star option, I'd deduct 1/2 star. Andrew needs to carry some oil rag buckets or something since he put a bunch of oily rags next to the sidewalk and I went out to clean them up (my dad saw them on his way out and text me and I said, it can't be the mechanic) and had to dig up some dirt since the rags were leaking oil. I'm not sure why he thought placing them on the ground was a good idea but oily rags on the ground is never good especially when it's raining. Overall, I'm happy with the repairs and the experience and will definitely consider using the service again especially since I'm working from home and don't get into my normal shop anymore.
