Question
I have a ryobi 775r string trimmer whose fuel lines I replaced. Now the primer pump cracked and needs to be replaced.  Where can I get a replacement for a model that old( 10-15 yrs)?

Getting parts is sometimes hard for old equipment, I can get you a replacement carb for around $40.00 plus shipping if you can find the carburetor make and part numbers then I may be able to cross reference that and get a break down. All we show when we look up the model # of the trimmer is a carb part # no make or breakdown of the carb
