Your gas trimmer can wield much power to get through tough yard work in a jiffy. The best weed eater can have challenges at one time or another.

With wear and tear, the gas line can become blocked, bent or even split, especially if the line is made of plastic.

The components can become dry and cracked and let in air, which will in turn block the free flow of gas.

If you suspect trouble on the line, first check the lines and remove any clogs where visible. Next, locate and replace any defective parts as needed.

Some of the tools you will need include:

  • Scissors
  • Gloves
  • Needle-nose pliers
  • Screwdriver
  • Used rag/paper towels
  • Approved gas can
  • Wire clothes hanger

Step #1:

Disconnect the spark plug wire from its outlet. Separate the spark plug wire from the plug. Never let them touch each other.

Step #2

Drain the gas tank in a well-ventilated area. Pour the gas through a funnel into the weed eater gas can. The funnel will help channel gas more efficiently into the can and minimize spillage.

Step #3

Remove the gas line from the carburetor. It can be done manually, or with a pair of needle-nose pliers. Be careful to absorb or wipe away any spills as you go along.

Step #4

Locate the two screws that secure the gas tank into the trimmer.  Loosen with a screwdriver and store them for reconnecting later. Take the fuel tank out.


Take the two gas lines out of the weed eater separately. If they are damaged, it’s best to discard them. As soon as the gas lines come off, the filter will slip out as well.

In case you may not be aware, the filter is shaped like a small cylinder and is attached to the thin line in the fuel tank.  Keep the filter to reconnect it to the new gas line when ready.


Channel the line into the fuel tank. Feed the line into the same hole through which the defective line was removed.

Feed the new line into the holes, both small and large, where the gas tank’s lid is located. You can secure the line safely in lace using a needle-nosed pliers.

Step #7

You will also need to attach a gas line filter at the end of the tube. Simply insert it exactly back into place in the large opening.

Push a good amount of the lines through the fuel tank and be sure the gas line filter settles well at the bottom of the tank. If the lines are tight, lubricate them by coating outside of the line with a little oil.

Step #8

Once the fuel line is securely in place, reconnect the fuel tank to the weed eater and tighten it.

Be sure to reattach the fuel lines into their designated place within the carburetor. They should sit in the same positions as the original parts.


The last step is to put the spark plug wire back into the spark plug.

Fill the tank with gas and do a test run to ensure the weed eater is working. Once this is done, your weed eater should be ready to go.
