2. Remove the old primer bulb assembly from the right cover. Disconnect old fuel lines as required.
3. Draw or take a picture of the throttle control trigger in the right cover, then remove it and the cable from the cover.
4. Remo ... Read more ve the throttle cable from the right cover and set it to the side. It won\'t go far because the kill switch is still attached.
5. Removed the gas tank and all old/broken hoses/parts.
6. Installed the fuel line in the bottom of the tank. (This requires pulling the filter hose connection through the small hole in the bottom of the tank from the inside. Do not use pliers. Just feed the end of the hose through the hole and apply a steady pull to the hose and wiggle it around. The piece will pull through without breaking anything.)
7. Install the new return fuel line (mine was blue) on the primer bulb assembly.
8. Cut a bevel on the other end to make it easy to feed it into the side hole on the gas tank. This hose was a little long, so I had to cut about an inch off to make it fit correctly.
9. Install the fuel line (bottom of gas tank) to the connection on the cylinder side of the carburetor. This requires good light and long needle nose pliers, unless you want to remove the air filter. (this also removes the carburetor.)
10. Install the primer bulb in the right side cover with the short (clear) fuel line to the front.
11. Connect the front line (clear) to the fitting on the intake side of the carburetor.
12. Push the rear line (blue return line) into the hole in the side of the gas tank.
13. Re-install the throttle cable and trigger assembly to the right cover.
14. With the right cover in place, but not screwed down, and without replacing the left cover, add fuel to the gas tank and check for leaks.
15. Press the primer bulb several times to be sure it is operating properly and there are still no leaks.
16. If all is good, replace the left cover and install all the mounting screws.
Note: I had not used my blower for about 5 years, so I had to do the fuel/air mix setup found in the manual and replace the spark plug. Runs like a dream and no gas leaks.
No fuel getting to the motor; rotted fuel return line.
