BMW 325i Fuel Tank

Finding Out the Trouble with the BMW 325i Fuel Tank

The fuel tank is a very crucial part of every vehicle because it contains gas or diesel. It's important to know whether the BMW 325i fuel tank is worn or already has cracks because fuel is very flammable. You wouldn't want any fluid to leak out of your car that can cause fire, would you? So, go ahead and use some of these tips to troubleshoot your fuel tank at home.

Problem with the sensor

If your BMW 325i starts to experience issues with the fuel gauge, such as reflecting an empty gas when in fact, it's full; you may have a problem with the fuel tank. The dilemma at hand is caused by the sensor. It's generally affordable to replace the sensor, but it can be expensive on most vehicles that would require extra repair work. Better have this checked by an expert mechanic.

Rusty fuel tank

It's inevitable for a fuel tank to get rusty over time. So, you better do a regular check up to know whether or not it has already rusted. Take note that a rusty fuel tank will cause it to leak. Study the exterior of the tank, under the straps that hold it to the body frame. It usually gets rusty around that area and moisture builds up there. If it isn't too damaged, then you can just carefully scrape off the rust. If not, a replacement will be required.

Contaminated fuel

If you start to sense that your BMW 325i is experiencing power loss, stalling, or premature fuel pump and fuel-injector failure, then these are indications that the fuel is probably contaminated. It's not good to keep driving your car with impure fuel because it can affect the performance of your vehicle. You should take out the fuel tank and remove its impurities. Otherwise, you may have to replace it with a new one for a fresher tank.

Flaking fuel tank

If your BMW 325i runs on diesel, it's possible for the inner lining to flake. Regularly check up on the gas tank if you notice that the fuel line, pump, and filter are clogged up.

  • Things to Keep in Mind When Cleaning the BMW 325i Fuel Tank

    A clean BMW 325i fuel tank will significantly improve the performance of your vehicle. You wouldn't want to be driving around a rusty one, would you? Though it's hidden, it's still a good idea to keep it fresh and clean. Here are some things to keep in mind for the fuel tank's proper upkeep.

    • Keep the fuel tank clean.

      You must ensure to keep the fuel tank clean from any contaminants so that it won't negatively affect the performance of your car. There are available cleaners for tanks in auto parts stores; all you have to do is look for the right one.

      Before cleaning your fuel tank, make sure that it's empty. Half fill the tank with hot water and about a half gallon of muriatic acid. You can then apply the cleaner after you have emptied the tank from the previous mixture. Take note to wear thick rubber gloves because these cleaning products can irritate your skin. After a day, your fuel tank should be completely dry and clean. Also, remember to do the whole cleaning process outdoors because you might inhale dangerous fumes, which can be detrimental to the health.

    • Keep the fuel tank from being in contact with water.

      Water is heavier than gas and it will most likely be at the bottom of the fuel tank. The most effective way to maintain proper upkeep is to minimize the exposure of water to the fuel. There are several processes that you can do, such as fuel tank insulation, which is to stabilize fuel temperature. You can also recycle fuel by using water separators.

    • Schedule regular clean ups.

      It's good to set a time when to inspect the fuel tank if in case it's already filled with contaminants. Schedule a periodic tank inspection and cleaning. It is said that periodic treatments along with preventive doses of EAP-approved fuel biocides can contribute to extending the time gap when you should get the fuel tank cleaned.

    • Keep the fuel tank free of rust.

      The usual question that runs into your mind when it comes to the fuel tank is: How do I know if my fuel tank has rusted or is starting to rust? When inspecting the tank, don't forget to thoroughly check the bottom because that's the area that's prone to rusting.
