Fuel line had hardened and split. Could not prime carburetor.

Michael from DOVER, Delaware

2 of 2 people found this instruction helpful.
Difficulty Level:
A Bit Difficult
Total Repair Time:
30 - 60 mins
1. Dismantled outer cover and pull rope assembly to allow fuel tank to come loose.
2. Had ordered all fuel lines, fuel filter, primer bubble, and air filter from eReplacementParts, not just the one fuel line that had split.
3. Was a wise choice because another fuel line split during disassembly.
4. Model 322L trimmer fue l filter must first be pulled from fuel tank and cut off before fuel line can be removed. Be careful not to disrupt the rubber bushings in the fuel tank the fuel lines pass through. I had not ordered those. The bushings seal the fuel lines to prevent leaks. Mine didn\'t leak, but I had known, it would have been a good idea to have ordered the tank bushings as a good measure and reassurance you get no leaks.
5. When replacing all fuel lines remember to make a sketch where each fuel line connects. This is important. I should have listed this first. Two lines go to the carburetor and to go to the primer bubble. Don\'t trust your memory. Make the sketch.
6. The longer fuel line must be pushed into the tank and brought out the fuel cap opening first before you install the filter. Push the fuel filter and rest of fuel line back into the tank. Some fuel line may have to be trimmed.
7. I replaced the other fuel lines trimming off excess, making sure there were no kinks or pinched segments.
8. I reassembled the fuel tank making sure the tank tabs fit snugly into their respective slots on the trimmer body as well as the pull rope assembly. All the while making sure the fuel lines remained routed properly.
9. Finally I verified none of the fuel lines had come undone and reassembled the outer housing. The carburetor air filter was shipped pre oiled and was easily installed.
10. I installed a new spark plug that I had purchased locally.
Pay attention to the assembly before servicing. Clean your trimmer while it\'s apart with rags and WD40 or some other oil solvent cleaner.
I started the trimmer and it ran great. No leaks from fuel system. Ready to go.
