Avoiding Air Lock for Better FIS Performance

06.19.2014 · Posted in Automotive, cars

The issue of air lock usually occurs while changing the fuel filters, or while performing other maintenance activities of the FIS. Let us take a look at how the issue affects FIS and how it can be prevented.

Affects the overall performance of FIS

When air enters fuel lines, it obstructs the supply of fuel to different parts of FIS; the engine may not get an adequate supply of fuel. Inadequate supply of fuel causes damage to the engine and results in loss of power. This condition could further lead to poor/uneven idle, decreased fuel economy and poor overall performance of the FIS.

Takes a lot of efforts and money to resolve

Air lock is one of the major issues in FIS. As mentioned earlier, the fuel injectors are affected by it, and it is very difficult to remove the air from them. This process not only takes a lot of effort and time, but also costs a lot of money. To avoid the issue in the fuel lines, you can take certain preventive measures. A few of them are mentioned here.

Preventive measures

With these few preventive measures, you can avoid air lock. Here are two simple ways to prevent this.

Never run on low fuel levels

One of the major reasons for air lock is running the vehicle on low fuel level. Running on low level for a long period will not only cause the issue, but will also overheat the fuel pump and reduces its life. Therefore, make sure to avoid driving your vehicle at a low fuel level.

Care should be taken while replacing or servicing components of FIS

While fixing or replacing any of the components of FIS, make sure you tighten them well. If any gap is left, it will allow the air to enter the fuel lines, causing air lock. Also, make sure that the fuel is filled first while replacing the fuel filter. Otherwise, air is introduced to FIS and causes the issue.

It is important to avoid air lock because it damages FIS, and results in loss of power, which in turn can damage the engine. You can avoid it with proper care, maintenance and following the simple preventive measures we discussed in this article.
