Replacing Fuel Lines: Pontiac G5 Two-Door Guide

Replacing the fuel lines on a two-door Pontiac G5 is a maintenance task that can be completed in a few steps. Before beginning, it is important to have the necessary tools, such as a fuel line quick disconnect tool, and to depressurize the fuel system by pulling the fuel pump relay out of the fuse box and starting the car. This guide will walk you through the process of replacing the fuel lines on your Pontiac G5, ensuring a smooth and efficient process.

Depressurise the fuel system

To depressurise the fuel system of a Pontiac G5, follow these steps:

Firstly, locate the fuel pump relay in the fuse box. Pull it out, then start the car. The car will splutter and die. You can then turn off the car and replace the relay.

This process will depressurise the fuel system, and you can now move on to replacing the fuel filter.

It is important to note that this process should not take longer than 15 to 20 minutes. Before beginning, ensure you have the fuel line quick disconnect tool, as this process will be very difficult without it.

Once the fuel system is depressurised, you can move on to the next steps of replacing the fuel lines:

• Go to the rear of the car and locate the fuel filter.
• Remove the two fuel lines that are circled in red. It may be easier to access these lines if you unclamp and move the wires circled in blue.
• Using the fuel line quick disconnect tool, remove the fuel line circled in green.
• Finally, remove the bolt in yellow, and the fuel filter will be ready to come out.

Disconnect the fuel filter

Disconnecting the fuel filter on a Pontiac G5 involves several steps. Firstly, depressurize the fuel system by pulling the fuel pump relay from the fuse box and starting the car. The car will then turn off. Replace the relay, and go to the rear of the car to locate the fuel filter. Next, remove the two fuel lines that are connected to the filter. You may find it easier to access these lines if you unclamp and move any wires that are in the way.

Now, to disconnect the fuel filter itself, you will need to remove the bolt holding it in place. Then, using a fuel line quick disconnect tool, remove the fuel line from the filter. This will allow you to fully disconnect the fuel filter from the engine feed fuel pipe. Tilt the fuel filter downwards and drain the fuel into an approved container.

Remove the fuel lines

To remove the fuel lines from your Pontiac G5, you will first need to depressurise the fuel system. Do this by pulling the fuel pump relay out of the fuse box and then starting the car. The car will splutter and die. You can then turn off the car and replace the relay.

Next, go to the rear of the car to locate the fuel filter. You will need a fuel line quick disconnect tool to remove the fuel lines. Remove the two fuel lines that are circled in red. You can get better access to the fuel lines by unclamping and moving the wires circled in blue. Then, remove the fuel line circled in green using the fuel line quick disconnect tool. Finally, remove the bolt in yellow, and the fuel filter will come out.

Replace the fuel filter

To replace the fuel filter on a Pontiac G5, you will need a fuel line quick disconnect tool. This process should take no more than 15 to 20 minutes.

First, depressurize the fuel system by pulling the fuel pump relay out of the fuse box and starting the car. The car will then turn off. Replace the relay.

Go to the rear of the car and locate the fuel filter. Remove the two fuel lines that are circled in red. You can unclamp and move the wires circled in blue to access the fuel lines more easily. Next, remove the fuel line circled in green using the fuel line quick disconnect tool. Finally, remove the bolt in yellow, and the fuel filter will be released.

Now, put the new fuel filter in place. Reinsert the bolt from the yellow circle, and put all the fuel line fittings back on the filter. Don't forget to put the wires back into the clamps if you moved them.

Finally, repressurize the fuel system. Do this by placing the key in the ignition and turning it to the "ON" position. You should hear the fuel pump making a whirring sound. Check the fuel lines at the fuel filter for any leaks. Turn the key back to "OFF" and wait 10 seconds. Then, turn the key to the "ON" position again, wait for the fuel pump to finish pressurizing, and you are ready to start the car. Check for leaks one last time, and you are ready to drive.

Repressurise the fuel system

To repressurise the fuel system of your Pontiac G5, follow these steps:

Place the key in the ignition and turn it to the "ON" position. You should be able to hear the fuel pump making a whirring sound. Check the fuel lines at the fuel filter for any leaks. Turn the key back to "OFF" and wait for 10 seconds. Then, turn the key to the "ON" position again. Wait for the fuel pump to finish pressurising, and you are now ready to start the car. Check for leaks one last time, then you are ready to drive.
