Return Grommet

Removed carburetor to a access fuel lines & primer pump, used wire with hook to remove the fuel filter. I replaced the fuel line fuel filter & primer pump. Then I dissembled the carburetor cleaned it in my ultrasonic cleaner resembled, reinstalled, checked the compression 110 lb. cranked it up it ran fine, oiled the blade.

1.Drained gas to make sure any crap was removed.
2. Pulled the fuel line with the filter somewhat out of the tank, squeezed it to make sure no leaks and not clogged. It just dropped out when I drained the tank. It was still good and not brittle or stiff, so did not use the replacement line I bought.
3. Removed gas return pipe with needle nose pliers. It was broken and still and brittle. When i pulled on the return line at the grommet end at tank,the grommet came out and apart in pieces)
4. Checked for grommet trash in tank, there was none. Sometimes you get lucky!
5. Put a smear of oil on one end of return line and inserted into the new grommet by twisting. It inserted just fit flush with bottom of grommet. I wasn't sure if some of the line was supposed to stick out of the grommet into the tank but there was some resistance with getting it all the way through, so I thought that as long as the gas was not leaking from the pipe or grommet and gas was going back to tank was OK. It Was.
6. Inserted one edge of grommet with return line in it into gas tank hole. Used a small screwdriver to mash rest of grommet into tank hole until seated. Took it easy so as not to tear it or return line.
7.Replaced other end of return fuel line to carb with needle nose pliers. A little tight working space but not too bad.
8. Checked return line to make sure there were no kinks and squeezed fuel bulb which still had a little fuel in it to make sure it was clear and sent fuel to tank.
9. Fueled up, pressed primer bulb, checked for leaks. There were none.
10. Started blower, checked for leaks. No leaks! Success!

Replaced the gas line grommet, easy!

After looking closer at the problem while getting ready to install the new parts, all that was needed was the Fuel Line which was cracked.
It was a bit difficult to get the grommets out because they were a bit greasy. It was necessary to remove the gas tank which was not possible because on screw would not come out.
When trying to thread the fuel line back through the grommet a bit of "3-in-one oil" made it easier.
The Fuel Pipe had to be 'fished' out of the gas tank opening because of the filter on the end.
Also it was a struggle trying to get the grommets snapped back in the holes.

-Removed the old grommet and fuel line.
-Installed the new grommet without the return line. Put oil or vaseline on the grommet to make it easier to push in the hole.
-Lubricate the outside of the fuel return line, and cut the end of the line at a sharp angle. Then split the line. This allows you to get it started in the grommet easily.
-If you want, reach inside the tank with a wire hook and pull the return line far enough to cut the end square with snips. Optional.
-Slide the other end of the fuel return line on the carburetor.
That is it!

0. Remove the remaining fuel from the tank. Using a funnel I put the fuel back into my 1 gallon gas can.
1. Removed the air cleaner cover.
2. Removed the hardware holding the tank in place.
3. Disconnect the fuel lines at the carburetor and primer, paying close attention to which line goes where.
4. Installed the new vent, return line and fuel line and filter into the new tank.
5. Removed the old primer and installed the new one.
6. Attached the new fuel lines to the correct places on the primer and carburetor.
7. Placed the new tank into position using the mounting bracket and screws attached the tank to the engine.
8. Filled the tank with fuel.
At this point I tried to start the saw, it would not start. I found that I had flooded the carburetor when I was checking the operation of the new primer.(guess I primed it one to many times!) Removed the spark plug then, using compressed air I dried the inside of the cylinder and the spark plug, reassembled and started the saw.
9. Installed the new air cleaner I had purchased and reinstalled the air cleaner cover.
10. Put the saw back to work trimming trees.

Removed old grommet and gas-drenched air filter element and replaced with eReplacement parts. Commercial Tanaka trimmer works great again.

Used needle nose pliers to remove the old parts and replaced with the new ones.

Replaced grommet - No leaks

Replaced grommet, and fuel pipe assembly at the same time.
