How to Identify Bad Fuel Lines?

Fuel lines are made of rubber hoses and are located in the fuel injection system. Their main job is to transfer the fuel from one place to another.

After a while, the rubber might start to degrade gradually. If you are cautious, you can easily identify bad fuel lines with ease. The symptoms it would show if the fuel lines are bad-

Fuel Odor

Fuel odor would start to leak out from the vehicle. It would lead to drying out the fuel hoses and then lead to leaking the fuel vapors. These leaks of fuel vapor would produce a faint or even odor of gasoline.

Engine Misfiring, Hard Starting, and Stalling

Any sort of leak in the fuel line would affect the vehicle’s performance as well as compromise the engine. Engine misfiring, hard starting, and stalling all are due to broken hoses in the fuel line.

Fuel Leak

Any rupture in the fuel line would cause a visible fuel leak. It will mostly be dripping and sometimes can even create a puddle of fuel under the vehicle. It would cause the fuel to run out sooner than usual.

As soon as you see any of the symptoms, it is better to change the fuel line. Otherwise, it might cause some serious consequences.

Depressurizing the Fuel Line

Before disconnecting the fuel line, you have to depressurize it first. If you don’t then it might burst into your face when disconnecting. Because it contains a lot of pressure to keep the fuel running. 

Thus, you need to depressurize it first by following a few steps-

Step 1: Removing Fuel Line Fuse

You have to pick up a long nose plier first. Then locate the fuse and remove it by the plier.

Step 2: Emptying the Fuel Tank

Now, start the engine till the fuel runs out and stops. If it doesn’t start, keep on turning the engine over for 10 seconds.

That’s it! The fuel system has now become depressurized and safe to disconnect. You can even use a gauge to check the fuel pressure. 

Disconnecting the Fuel Line Without Tool

You need to disconnect the fuel line to avoid any kind of consequences. Such as fuel leaking to even the vehicle becoming not drivable.

You can very easily disconnect the fuel line if you go to any car shop. But they will charge a lot for this simple task, which you can do on your own.

However, not everyone has the tools at their home to do this thing. That is why we are going to explain how you can disconnect the fuel line without any tools.

For Push Lock Fuel Line

This type of fuel line fitting has three clips. Which hooks up and locks the fuel line with the fuel filter. The tool one might buy will help unhook the clip to disconnect it from the filter.

Doing it by yourself would save you a lot of time and money. There are a few steps that you need to follow-

Step 1: Getting the Length by the Fuel Filter

Before measuring the length, remove the safety hook from the fuel line. Then you can easily measure the length of the exposed portion of the fuel line. But you have to shorten the length a little bit when measuring with a scale. 

Step 2: Cutting the Sharpie Cap

You have to choose a sharpie and take off the cap. Then cut it at that exact length that we measured before. That would be approximately ¾ inch. After that, cut a slit in the middle for it to fit onto the line.

Step 3: Disconnecting the Fuel Line With the Cap

Slide the cap onto the exposed fuel line. Then slide the cap into the fuel fitting line with one hand. Then try to pull the fuel line with the other.

After a while, the cap would release the hook that is retaining the fuel line. And then it would be disconnected completely.

Now, you can easily disconnect the fuel line from the fuel filter. To reconnect, you just have to insert the fuel line back into the fuel filter. Try pushing it till you hear the click sound. After that, it is good to go.

Making a Homemade Fuel Line Disconnecting Tool

You simply cannot disconnect the fuel line only with your hands. It has a push lock system inserted into it. That is why you need a tool to disconnect it. You can very easily make it on your own at your house.

First, you have to take off the cap of a sharpie or even a bottle cap. For the sharpie cap, just cut it with a saw at the exact length. For the bottle cap, drill a hole into the middle at the exact diameter. Then cut a slit in the side for it to slide onto the fuel line. 

That is how you make a tool to disconnect the fuel line. You can even use a 3D printer to make one for you or even buy one online. 

Things to Consider When Disconnecting Fuel Line

You got to know how you can disconnect the fuel line. But only knowing how to do it is not enough. Because there are a few things to consider before trying to disconnect the fuel line.

  • You should wear safety gloves and glasses.
  • Keep all kinds of fire and spark away from it.
  • You should have a fire extinguisher close to you.

Now you can safely disconnect the fuel line on your own.


Where is the reset button for the fuel pump?

There is a red-colored reset button on top of the shut-off switch of the fuel pump. It is located at the right rear quarter trim panel, which is near the life gate.

What are the ways to check fuel pressure without a gauge?

There are two ways you can do it. One is by using an OBD scanner, that will provide live data of the pressure. Another is by turning the keys on. If you only hear a buzzing sound and no other symptoms, the pressure is normal.

What are the symptoms of low fuel pressure?

Symptoms of low fuel pressure include- difficulty faced in starting the car and engine light turning on. It also causes the throttle to become unresponsive, low performance, and the engine to stall.


Hope you got a clear idea about how to disconnect fuel line without tool.
