Most of the older cars on the market have a carburetor that helps to disperse the fuel that is need during the combustion process. While these carburetors are very reliable, there are a number of repair issues that can render them unusable. With all of the different parts that it takes to make a carburetor run, it can be a bit overwhelming to keep up with them all. The fuel return hose is designed to take excess gas out of the carburetor and take it back to the gas tank. For the most part, this hose is used constantly during the running of the vehicle.

The hoses on a car can last anywhere from 10,000 to 50,000 miles considering the conditions that they are exposed to. The fuel return hoses help to prevent the carburetor from flooding due to the fact that it removes the extra fuel. These hoses also reduce the amount of wear on the fuel pump by reducing the occurrence of vapor lock. Just like any other hose on your car, eventually the fuel return hose will have to be replaced due to wear. Neglecting to act when repair issues are discovered can lead to a number of additional issues. If you find that there is a problem, have the car inspected by a professional and replace the fuel return hose if necessary.

Usually, this hose will not be inspected during routine maintenance. By taking the time to look at the hose on occasion, you will be able to spot issues and get them repaired before any real damage is done. The heat from the engine will eventually lead to the rubber hose drying out and becoming very brittle. If you start to notice that the hose has visible damage or cracking, then you will have to take the time to get the right repairs done.

Here are some of the other signs that you may notice when it is time to replace the fuel return hose on you vehicle:

  • There is a noticeable gas smell from under the hood of the car
  • Gas puddles under the car
  • The carburetor is flooding easily and will not keep the car running

Getting these lines replaced in a hurry is essential in reducing the danger that leaking gas can bring. Allowing the professionals to handle this type of work will reduce the chance of any further issues.
