What Is a Fuel Line?
The fuel line is a hose that transfers gas from the storage tank to your engine. Fuel lines attach to pumps that push gas into the engine so the car can run. Given that the fuel line carries all the gas, fuel line problems affect engine performance and efficiency.
Chevy Cobalts, in particular, are susceptible to fuel line problems. Over 600,000 Chevy Cobalts have been investigated for having fuel line and ignition problems.
The models most affected by this defect are the 2009-2010 year models.
How Much Does a Chevy Cobalt Fuel Line Cost?
The Chevy Cobalt is relatively inexpensive to maintain, with an average annual maintenance cost of about $450. However, in some cases, parts for a Chevy Cobalt can be more expensive than equivalent parts for models still in production.
This is because most manufacturers do not still produce parts for discontinued models.
Here is a quick table showing the average prices of fuel line parts for Chevy Cobalt models over the years. The prices were calculated by comparing parts costs on several popular auto parts websites.
As you can see, costs for a Cobalt replacement fuel line are pretty consistent across the board. The Chevy Cobalt uses a single ⅜” supply line, 1 ⅜” vapor line, and a fuel filter. The fuel lines are made from nylon and measure 7’ long.
If you have a problem with one fuel line, then you probably have a problem with the vapor line as well. That is why most manufacturers and vendors sell fuel lines in kits with at least two hoses.
Other Related Costs
Generally speaking, you will not just replace your fuel lines but also replace your fuel pumps and fuel filters.
The fuel pump draws gas from the storage tank to the engine. Fuel lines and pumps are closely connected so problems in one lead to another. Fuel pumps are more expensive than just fuel lines.
This table has a quick list of the average cost of pumps for various Cobalt models.
As you can see, fuel pumps are generally more expensive than fuel lines, but they are an integral part of a working fuel system. If you buy a fuel pump from a registered parts dealer, you can often get a warranty on any parts you buy.
As far as labor goes, you can expect to pay between $100 to $250 for installation. The cost of installation is affected by the car’s age.
Fuel pumps are pretty durable but they still need to be replaced every now and then. Experts recommend getting your fuel pump switched out once every 100,000 miles or so.
The fuel filter is another important part of the engine. The fuel filter keeps particles and dust out of your lines and engines.
Broken filters can cause build-up in the fuel line and lead to damage. Experts recommend changing your fuel filter after 30,000 miles or once a year. Keeping your fuel line clear will increase engine efficiency.
The table below has average prices for Chevy Cobalt fuel filters.
Fuel filters tend to be cheap and there are several models that are compatible with every year in the Cobalt line. Compared to many other cars, Cobalt parts are pretty flexible.
Most compatible models are compatible with the 2005-2010 line.
Factors that Affect the Cost of a Chevy Cobalt Fuel Line
- Vehicle age. All other things being equal, older Chevy Cobalt models are cheaper to repair. Newer models have more advanced systems and computer integration which increases labor costs.
- Additional issues. Fuel lines are an integral part of the car and usually co-develop with other issues. For example, if you replace your fuel lines, your mechanic will most likely recommend you also replace your fuel pump.
- Manufacturer or shop. Generally speaking, it is more expensive to buy individual parts directly from the manufacturer instead of an independent shop. However, you can usually get a warranty if you buy from the manufacturer or a registered dealer.
Signs of a Bad Fuel Line
Here are some of the most common symptoms of a broken fuel line.
Fuel Leaks or Odor
The most obvious sign of a broken fuel line is unexplained fuel leaks or a fuel odor. As lines wear out, gas will condense and drip out on the ground under your car.
Leaks can be near the front or the back of the car, depending on where the leak is.
Another sign of a broken fuel line is inefficient engine performance. Leaky fuel lines mean that not enough fuel is getting to your engine and that you will burn through gas quicker.
A broken fuel line can also lead to engine problems down the road.
If a fuel line is broken, then gas flow to the engine will get interrupted. This will cause sputtering or engine misfiring.
In the worst cases, a broken fuel line will prevent you from starting the car at all.
Smoke coming from your engine can mean a broken fuel line. Broken lines leak fuel which can be ignited by the hot engine components.
If you see smoke coming from your engine, immediately turn off your car and move a safe distance away from the vehicle.
