What You'll Learn
Fuel line repair/replacement
The Chevy Cobalt has two fuel lines.
If your Chevy Cobalt is leaking fuel, it is most likely due to a leak in the fuel lines, especially where they bend to go up over the back axle. The first step is to inspect the lines to determine the extent of the damage. If the lines are severely rusted or corroded, it is best to replace them entirely. You can choose to use genuine Chevy parts or opt for a more affordable option from third-party sellers.
There are a few different approaches to repairing or replacing the fuel lines. One method is to cut the damaged lines and install high-pressure gas hose or tubing in their place. This can be shaped to fit around the bend and attached to the filter. It is important to ensure that any hose used is suitable for high-pressure gas and will not crush when making tight bends.
Another option is to use a fuel line repair kit, which typically includes a pre-cut braided stainless steel fuel line that is resistant to rust, dry rot, and cracking. These kits are designed to be easy to install, with some users reporting that it can be done in about an hour. The process involves removing the factory clips and using the supplied steel clips and fasteners to secure the new fuel line at the factory clamp locations.
Additionally, there is a "service fuel system" procedure that includes blowing out the lines, replacing the fuel filter, and draining the tank. This procedure is more involved and may take around 2.6 hours to complete.
It is important to note that repairing or replacing fuel lines can be a complex task, and it is always recommended to seek professional assistance if you are unsure about any part of the process.

Fuel line leaks
The Chevy Cobalt has been the subject of investigations by the National Highway Traffic Safety Administration (NHTSA) after the agency received numerous complaints regarding fuel leaks. Owners of the Cobalt reported strong odors of fuel and leaks to federal safety officials, with 208 complaints received by the NHTSA specifically regarding fuel leaks. Of these, 39 complained of fuel leaking from a line near the left rear wheel. The safety watchdog claimed that the leaks were caused by corroding metal fuel lines.
The investigation involved 614,000 Cobalt and HHR models, with the Cobalt models affected being from the 2008 to 2010 model years. Owners of these vehicles reported similar issues with fuel leaks, with one owner of a 2009 Chevrolet HHR stating, "The gas line is rusted and leaking. There is a strong odor of gasoline at the rear driver's side tire of my car. It leaves fuel on my driveway." Another owner of a 2008 Chevrolet Cobalt wrote, "Gas line corrosion problem (due) to the muffler right under gas lines and gas line up in pocket where heat and moisture cause early corrosion (poor design)."
In 2012, GM recalled nearly 50,000 models, including 2008-2009 Cobalts, due to a faulty fuel pump that could crack, especially in warm weather states. This issue was separate from the fuel line leak problem, but it highlights the potential dangers of fuel leaks and the importance of addressing them promptly.
If you suspect a fuel line leak in your Chevy Cobalt, it is important to take immediate action. First, you should check to make sure that it is indeed a fuel line leak. If it is, you can replace the fuel line or just the rusted piece in your backyard with a few jacks and jack stands. Cut out the old rusted piece and replace it with a new piece of fuel injection hose. Make sure to tighten the clamps and check for any other leaks. You can also refer to online resources and forums for guidance on repairing fuel line leaks, as well as purchasing fuel line repair kits. However, if you are uncomfortable with performing the repair yourself, it is best to consult a professional mechanic.

Fuel line tubing
The Chevy Cobalt has two fuel lines, which are prone to leaking, especially where they bend to go up over the back axle. This is a common issue, and there are several options for repair or replacement.
There are a variety of fuel line tubing options available for the Chevy Cobalt. The original equipment manufacturer (OEM) fuel lines are made of steel, which is durable but can be difficult to install due to its rigidity. This can make it challenging to bend the lines to fit the unique needs of your vehicle.
One option for repair is to patch the leaking area with a rubber fuel line or high-pressure gas hose. This is a more economical solution, as it is cheaper than replacing the entire steel line. However, it is important to ensure that any rubber hose used is capable of handling high pressures. Nylon hose is another option, but it can be prone to crushing when making tight bends, potentially causing fuel starvation.
For a more comprehensive solution, complete fuel line replacement kits are available, which include everything needed for a clean and complete installation. These kits typically feature pre-bent lines made of materials such as galvanized steel, stainless steel, or PTFE flexible hoses. The stainless steel options are resistant to rust, dry rot, and cracking, making them suitable for both gas and diesel engines. The flexibility of these lines makes them easier to install and ensures a precise fit.
When considering fuel line tubing options, it is important to prioritize safety and durability. While patching a leaking line may be a temporary solution, a complete fuel line replacement kit offers a more reliable and long-lasting fix, ensuring the fuel system is secure and efficient.

Fuel line cost
The cost of repairing or replacing the fuel lines in a Chevy Cobalt depends on several factors, including the model year, the extent of the damage, and whether you choose to use genuine parts or aftermarket alternatives.
For the 2007-2008 Chevy Cobalt models, the labor time for a fuel line replacement is estimated to be around 2.0-2.2 hours, although some mechanics may charge based on real-time. This labor cost will vary depending on your location and the mechanic's expertise.
If you are looking for a more affordable option, you can consider patching the damaged section of the fuel line with a few feet of rubber fuel line or high-pressure gas hose, which can be purchased for around $14. This approach is more cost-effective than replacing the entire steel line, as demonstrated by a Chevy Cobalt owner who spent $100 to replace about 12 feet of old line with a nylon line kit.
On the other hand, if you prefer a more comprehensive solution, you can opt for a Quick-Fix Fuel Line Kit, which typically includes a pre-cut braided stainless steel fuel line, steel clips, and fasteners. These kits are designed to be easy to install, resistant to rust, dry rot, and cracking, and compatible with both gas and diesel engines. The cost of these kits can vary, but they offer a secure and reliable option for replacing leaky fuel lines.
Additionally, you may need to factor in the cost of any specialized tools required for the repair or replacement, such as a fuel line disconnect tool set, which can be purchased separately.
It is always recommended to consult with a certified mechanic or a trusted automotive repair shop to get an accurate estimate for your specific Chevy Cobalt model and fuel line issue.
