Why is my car gas tank not opening?

In this article, we will touch upon the “my car gas tank won’t open” problem. While explaining the problem associated with the gas tank lid, we will explain the different causes behind the problem.

Why is my car gas tank not opening?

The reason behind the car gas tank not opening are as follows:-

  •  Rust builds up in the system.
  • The metal flap spring is broken.
  • Broken latch
  • The release cable is damaged.

Many people think that the metal flap on the car fuel tank is the same on every vehicle. However, this isn’t the case because some gas tank flaps pop open by lifting a lever, while others have a key lock in them. These metal flaps can get damaged easily and can prove to be extremely frustrating because they will hinder you from filling fuel in your vehicle.

If the metal flap on the gas tank in your vehicle isn’t closing, then you must first check the owner’s manual for the best possible cause of the problem. There are some general causes for the stuck metal flaps of the petrol tank.

  • Rust build up in the system.

One of the common reasons behind the stuck fuel lid is the rusting of the latch, which is present to grip the fuel lid in place. The fuel lid mechanism is open to moisture; thus, there are high chances of it getting rusted. Moreover, rusting damages the components of the latch used to hold the fuel tank lid. But it also causes rusting in the areas around the latch. 

Therefore, to reduce the effect of rusting on the working of the latch, one can lubricate the system. To lubricate the watching system, you can utilize WD40 lubricating oil on both the latch and the catch. Lubrication will reduce the effect of rust.

  • The metal flap spring is broken.

The latch mechanism of the fuel lid is employed with a spring which is responsible for the opening and closing of the fuel lid. Interestingly, the lever present in the cabin of the vehicle, when lifted, actuates the spring movement, which in turn unlocks the lid. If the spring is damaged, you need to replace the spring, and the problem of the stuck flap will be solved.

  • Broken latch

The latch used in the flap of the fuel lid has a similar working to the latches used in the bonnet and trunk of the vehicle. The latch mechanism uses spring as the main component for locking the flap of the fuel tank. When the flap is closed, the catch present on the flap of the vehicle strikes the latch lock. Once it strikes the latch, the catch gets locked, and it can be only opened by lifting the lever present near the driver’s seat.

In some cases, the latch of the vehicle can get faulty due to a broken spring or detachment latch release cable. In such a case, when you pull the latch release cable, the flap won’t open. Therefore, for fixing the faulty flap, you will need to change the latch. 

  • The release cable is damaged.

The fuel flap is locked with the help of a latch that is present in the car body. The operation of this latch is carried out with the help of a latch cable. This latch cable is connected to the lever, which is present inside the vehicle near the driver’s seat. When the driver lifts the lever, the tension in the cable releases the latch, which is similar to the bonnet latch working.

The latch release cable for the fuel lid travels through the underbody of the car. Hence, there are high caches of it getting rusted due to the water present on the roads. Thus, in that case, the strength of the wire slowly deteriorates and eventually, when the wire becomes completely rusted, it snaps. Therefore, in such a case, you only have one alternative, which is to change the wire.

Conclusion

In this article, we have addressed the “my car gas tank won’t open” problem. To address the issue of the faulty latch, we have explained the different causes which can develop the problem of the faulty flap. Moreover, some of the most common reasons behind the faulty latch are rusting and breaking of the spring present inside the latch. Moreover, we have also briefly explained how you could fix the faulty flap of the fuel tank.
