The diaphragm in the carb may need to be replaced. Make sure all your fuel lines are fine. On these inexpensive blowers the fuel lines tend to get brittle and crack and fall apart.

The little pump for gas does not wok


The primer does not necessarily need to work for the unit to run. It does have a choke to aid cold starts. However it is a good indication of something wrong in the fuel system. A primer bulb that does not return to shape or does so slowly indicates a clogged screen in the carb. Check the fuel filter and fuel lines. Replace the fuel lines if they are stiff or discolored, rebuild the carb and replace primer bulb.

Fuel leaks bulb not priming.


If you have a leak the bulb will not prime. Over time the either the rubber on the primer bulb gets a pin hole in it requiring bulb replacement or one of the fuel lines cracks and introduces air into the lines. Unless the system is completely sealed the primer bulb will not work. Make sure all of the connections on the fuel lines are tight and correct the system leaks.

Thanks for choosing FixYa.

Diagram of fuel lines for ryobi 280r leaf blower


The line out of the bottom of the fuel tank goes to the curved brass line coming out of the carburetor and the straight brass line out of the carburetor goes to the short side coming out of the primer bulb. The long side of the primer bulb goes back to the fuel tank.

My prime button broke can i bypass it


No, you cannot bypass it. Even if you could get it to run without the bulb there would be a significant chance of fire and injury. Replacement Ryobi primer bulbs are very common, you can get one just about anywhere...in fact, you can go to Google, put in Ryobi and whatever the model number is of your trimmer and the words primer bulb and you will get plenty of hits for parts companies that carry the replacement bulb.
