Ryobi fuel lines

chevyssruleFebruary 20, 2010

Good Evening,

I have a Ryobi 790r trimmer what I need to know is how the fuel lines run.

There are two going to the carb one goes to the top the other to the bottom. So I guess on is the inlet the other the return line. I need to find out does the top line run from the carb to the primmer bulb or the bottom line?. As I do not know which one is the inlet & which one is the return? If anyone can explain how these two fuel lines run it would be a big help!.

Thank You,

connect the top of carb hose to the short primer bulb stem. The bottom carb hose to the fuel line that has the filter on it inside the tank. Finally, connect the remaining fuel line that comes out of the fuel tank to the center or the longer stem of the primer bulb.
hope this helps,
