Craftsman Model 358797290: Replacing Fuel Lines Like A Pro

If you're looking to replace the fuel lines on your Craftsman 358797290 leaf blower, you've come to the right place. This repair guide will walk you through the process step-by-step, so you can get your leaf blower running like new again. Before you begin, make sure you have the necessary parts, including the small and large fuel lines, which can be purchased from Sears PartsDirect.

Remove the cylinder shield

To remove the cylinder shield of your Craftsman 358797290 leaf blower, you will need a screwdriver.

First, place the leaf blower on a flat surface, preferably a table at waist height, and put on work gloves.

Next, use the screwdriver to remove all the nuts on the cylinder shield. Most Craftsman chainsaw models come with 3-4 nuts on the shield. Once the nuts are off, you can remove the cylinder cover.

Take out the air filter and check if it can be replaced after washing it with fuel. If it is dirty and no longer functional, you will need to replace it.

Finally, disconnect the spark plug.

Disconnect the spark plug wire and remove the air filter

Disconnecting the spark plug wire and removing the air filter is an important step in replacing the fuel lines on a Craftsman model 358797290. Here is a detailed guide on how to perform this step:

First, locate the spark plug wire. It is usually connected to the spark plug, which is often located near the engine. Once you have located the wire, carefully disconnect it from the spark plug. This step is crucial as it ensures that the engine does not accidentally start while you are working on it.

Next, move on to removing the air filter. The air filter is typically housed within an air filter housing, which can be found by following the spark plug wire from the spark plug. Using a screwdriver, carefully remove the screws or bolts holding the air filter housing in place. Once the housing is open, you should be able to locate and remove the air filter itself.

It is important to note that the air filter may be dirty, especially if it has not been replaced in a while. If this is the case, you may need to replace it with a new one. Additionally, it is recommended to wear work gloves and safety goggles during this process to protect your hands and eyes from any debris or fuel residue.

After removing the air filter, set it aside and ensure that you keep track of all the screws or bolts you have removed so that you can easily reassemble the components later.

By following these steps, you will have successfully disconnected the spark plug wire and removed the air filter, allowing you to access the fuel lines and proceed with the replacement process for your Craftsman model 358797290. Remember to refer to the repair manual or seek professional guidance if you are unsure about any steps or procedures.

Remove the fuel filter

To remove the fuel filter from a Craftsman model 358797290, you will need a steel coat hanger.

Firstly, straighten out one end of the coat hanger and slide it into the fuel tank to bring out the fuel filter. You will then need to detach the fuel line from the filter.

If you are replacing the fuel filter, you will need to purchase a manufacturer-approved fuel filter to ensure the best performance.

If you are removing the fuel filter as part of a larger fuel line replacement, you will need to remove the cylinder cover and air filter, air filter housing, carburetor, and fuel line before removing the fuel filter. You will also need to disconnect the spark plug.

Remove the carburetor

To remove the carburetor from your Craftsman model 358797290, you will first need to prepare your equipment and work area. Ensure you are wearing appropriate safety gear, including gloves and eye protection, and that your leaf blower is switched off and cooled down. Place the leaf blower on a flat, waist-height surface, so you can work comfortably without bending over.

Next, remove the old fuel from the tank. Use an old container to collect the fuel and keep it nearby. Now, remove the cylinder cover and air filter. Unscrew all the nuts on the cylinder shield, and then remove the cover. Take out the air filter and check if it needs to be replaced. If it is simply dirty, you may be able to wash it with fuel. You may also need to replace the fuel filter.

Now, disconnect the spark plug. Remove the two bolts holding the air filter housing and carefully pull it out, keeping the nuts and bolts in a container so they don't get lost. The throttle linkage will be attached to the backside of the air filter housing, so be careful not to damage it. Take a photo of the arrangement so you can remember how to reassemble it later.

With the air filter housing removed, you should now be able to see the carburetor. Before you can remove it, you will need to disconnect the fuel and vent lines. Use a flathead screwdriver to do this, and if the connections are too tight, use some WD-40 to loosen them. Once the fuel and vent lines are removed, pull the carburetor out carefully.

Install the new fuel lines

To install the new fuel lines, you will need to cut the new fuel lines at an angle to thread them into the tank. Use a pair of scissors to cut the lines. Push the large line about 1 inch into the tank. Push the small line into the tank, too, but ensure it goes far enough so that it can be grabbed through the mouth of the tank with a pair of needle-nose pliers.

Now, pull the small line out of the mouth of the tank. Cut the end square and install the fuel filter. Pull the line back in so that the filter rests on the bottom of the tank. Trim the fuel lines and connect them to the carburetor.

To ease threading, lubricate the fuel lines with a drop of oil.
