Nylon fuel line repair kits

If you are looking to replace the fuel line on a Chevy HHR, there are a few options for Nylon fuel line repair kits. It is important to note that some fuel lines are made from hard steel or rubber, which can be more prone to rust and leaks. Nylon fuel line repair kits are designed to replace these original factory lines and provide an easy installation process.

One option is the Inline Tube Nylon Fuel Line Repair Kit, which is available for the 2006-2011 Chevrolet HHR. This kit includes both the fuel supply line and the vapor emission line, as well as couplers, hose barb to quick disconnect fitting, zip ties, and safety tags. The fuel supply line runs from the tank to the mid-section of the car, while the vapor emission line runs from the charcoal canister to the mid-section. The kit is engineered for an easy install that does not require the removal of the original hard lines.

Another option is the MUCO Nylon Fuel Line Kit NFR0019, which is compatible with the Chevy HHR 2006-2011 2.2L, 2.4L engine models. This kit includes both the fuel and vapor vent lines and is designed for an easy installation process.

There are also braided stainless steel fuel line kits available, such as the one recommended by Oldblue in the ChevyHHR forum. These kits are known for their durability and corrosion resistance. When choosing a fuel line kit, it is important to consider the specific make and model of your Chevy HHR to ensure compatibility and ease of installation.

Additionally, when replacing the fuel line, it is important to be aware of other common issues that may arise, such as problems with the control arm bushings and hardware, which can cause difficulties for mechanics during the installation process and increase the overall cost of repairs.

Fuel supply line

The fuel supply line is the line that runs from the fuel tank to the engine of your Chevy HHR. It is responsible for carrying the fuel from the tank to the engine, where it is combusted to power the vehicle.

Over time, the fuel supply line can become damaged or clogged due to rust, debris, or other factors. If you notice any leaks, it is important to replace the fuel supply line as soon as possible to prevent further damage and potential safety hazards.

To replace the fuel supply line, you will need to purchase a replacement line that is compatible with your specific Chevy HHR model. You can find these replacement lines at automotive stores or online. When purchasing a replacement line, it is important to consider the material it is made of. Some options include nylon, braided stainless steel, or multiple pieces. Each material has its own advantages and disadvantages in terms of durability, ease of installation, and cost.

Once you have purchased the replacement fuel supply line, you will need to remove the old line from your vehicle. This may involve disconnecting it from the fuel tank, engine, and any other components it is attached to. It is important to be careful during this process to avoid damaging any other parts of your vehicle. Refer to your vehicle's repair manual for detailed instructions on removing and replacing the fuel supply line.

Vapor emission line

The vapor emission line is a crucial component of the fuel system in a Chevy HHR, and it often requires replacement due to corrosion and leaks. Here's a detailed guide specifically focused on the vapor emission line:

Identifying the Vapor Emission Line:

The vapor emission line is one of the two main fuel lines in the Chevy HHR, along with the fuel supply line. The vapor emission line runs from the charcoal canister to the mid-section of the car or the engine. It is responsible for carrying vapors from the fuel tank to the engine, where they can be burned along with the fuel.

Symptoms of a Faulty Vapor Emission Line:

A faulty vapor emission line may exhibit similar symptoms to a faulty fuel supply line. These can include:

• Leaks: If you notice fuel leaks underneath the vehicle, especially near the rear driver's side, it could indicate a broken or corroded vapor emission line.
• Performance Issues: A faulty vapor emission line can affect engine performance, including reduced fuel efficiency and difficulty starting the engine.
• Check Engine Light: The "Check Engine" light coming on could be due to a faulty vapor emission line, indicating an issue with the evaporative emissions system.

Replacing the Vapor Emission Line:

• Sourcing the Correct Parts: Ensure you purchase a vapor emission line compatible with your Chevy HHR's specific year and model. Several companies offer replacement kits, including Inline Tube, RockAuto, and Amazon.
• Jacking Up the Vehicle: For easier access to the fuel lines, jack up the HHR and place it on jack stands with the front end higher.
• Releasing Fuel Pressure: Before working on any fuel lines, it's crucial to release the fuel pressure. Do this by disconnecting the fuel pump fuse in the underhood fuse block and then starting the car.
• Removing the Old Vapor Emission Line: Start by removing the old vapor emission line, working from the front of the vehicle towards the rear. Be careful when handling the old line, as it may be brittle or damaged.
• Installing the New Vapor Emission Line: Begin at the rear of the vehicle and work your way forward when installing the new line. Ensure all fittings are clean and lubricated with a small drop of clean engine oil to protect the O-rings. Use the retaining clips to secure the new line in place.
• Refilling and Testing: Once the new vapor emission line is installed, refill the fuel tank and reconnect the fuel pump fuse. Start the engine and check for any signs of leaks or issues.

By following these steps, you can effectively replace the vapor emission line in your Chevy HHR, ensuring a safe and reliable fuel system. Remember to take all necessary safety precautions when working with fuel lines, and always refer to a qualified mechanic if you have any doubts or concerns.

Fuel line rust

If you notice a fuel smell from the rear driver's side of your Chevy HHR, it could be a sign of a rusted and leaking fuel line. This issue has been reported by several Chevy HHR owners, particularly those with 2006-2007 models. The fuel line runs along the rocker panel, and the rusted spot is usually found in front of the rear tire.

The rusting of the fuel line is likely due to a combination of factors, including the car's low clearance, the proximity of the fuel lines to the exhaust, and exposure to salt and moisture from winter weather conditions. Some owners have suggested that the design of the fuel lines may be flawed, and that GM should issue a recall for this safety hazard.

If you discover a rusted fuel line, it is important to address the issue promptly to prevent further damage and ensure your safety. Depending on the extent of the rust, you may be able to repair the line by removing the rusted section and installing a compression fitting. However, if there are multiple rusty areas or the problem is widespread, it is recommended to replace the entire fuel line.

When replacing the fuel line, consider using a nylon kit or a braided stainless steel kit for improved durability. You can find pre-bent fuel line kits specifically designed for the Chevy HHR, ensuring a precise fit and meeting or exceeding OEM requirements. These kits typically include galvanized steel lines with plated fittings and hardware, as well as flexible hoses made from stainless steel or PTFE for corrosion resistance.

Fuel line leaks

If you suspect a fuel line leak, the first step is to inspect the fuel lines for any signs of rust or corrosion. You can also check for any fuel dripping or puddling near the fuel lines. If you notice any issues, it is important to address them as soon as possible to prevent further damage and potential safety hazards.

To replace the fuel lines, you will need to purchase a fuel line replacement kit. There are a few different options available, including nylon and braided stainless steel kits. The kit should include all the necessary parts to replace the entire fuel line, from the fuel tank to the engine.

Once you have the replacement kit, the next step is to remove the old fuel lines. This may require some mechanical knowledge and skills, so if you are not comfortable with the process, it is best to consult a professional mechanic. When removing the old fuel lines, be careful not to damage any other components, such as the brake lines.

After removing the old fuel lines, you can install the new ones, following the instructions provided with the replacement kit. Ensure all connections are secure and tight to prevent any leaks. Once the new fuel lines are installed, inspect the vehicle for any signs of leaks and test-drive the car to ensure it is running smoothly.

It is important to note that fuel line leaks can be dangerous and should be addressed as soon as possible. If you notice any signs of a fuel leak, such as a strong gasoline smell or dripping fuel, it is best to avoid driving the vehicle and have it towed to a repair shop for inspection and repairs.
