Whether you are aware of it or not, the cars you drive most likely uses something called a fuel injector. In the 1980s, vehicles drove with the help of carburetors. However, they were eventually all changed by fuel injection systems.
The real fuel injector itself can pose a problem if it starts to leak. If you see a problem, it is important to find the source. Often times the fuel lines running to the injector will be the cause because they no longer seal accurately, so this article will give you the tools the fix this malfunction by yourself.
WHAT IS FUEL INJECTION
Fuel injection is the system in your car that mixes fuel and air. Perhaps the most important thing to remember is that each and every fuel injection system is measured and set specifically to each type of fuel it will handle.
1 – A SIMPLE FIX
The first thing that needs to be done is to ensure the fuel system is depressurized. This is a simple work you can execute by allowing the engine to cool down and removing the fuel cap.
2 – REMOVE THE O-RINGS
From the firewall, you will see the return fuel line. You must first remove the quick disconnect fasteners. Then, when you remove the tube, you will find two orange O-rings inside. Remove them and replace them. Be sure to check the outlet line when you’re finished and repair it if necessary.
3 – SEAL AND TEST IT
With the new O-rings in place, use your quick connect line repair kit to change and secure any of your lines. To test if the leak is fixed, simply insert the key into the ignition and turn it enough so that an electrical current is running through the engine; you don’t need to turn over the engine. This is very important because you don’t want to accidentally start a fire if you have improperly mended your lines. With electricity flowing, check your fuel pumps for any leak. If you find them clean then you have completed your task.
4 – Remove the Fuel Injector Itself
If you find that this does not fixed your issue, it will become necessary to replace the injector itself. Finf your injectors, and simply slide a flat head screwdriver in the top of it to easily pop out the plug keeping it in place. Now you can use a fuel injector puller to remove the injector from the engine. Be very careful, though, cuz you don’t want to break any of the expensive engine pieces find around it.
Next, put the new fuel injector, making sure not to force anything into place. It will slide in once it settles properly. Then, you can reattach your fuel lines and everything should be good to go.
