Took the outer casing off, removed gas tank, carburetor off, separated the engine backwards about 1/2” and replaced the fuel lines while I was at it and had to be careful putting it back together once I was done I primed it 4 or 5 pulls and it was running good it was a lot harder than my chainsaw.

I had not used my trimmer for a while, and when I tried to prime it the bulb cracked, then the lines snapped when I tried to take off the bulb. I used a screwdriver to dismount the fuel tank. To install the new tank I had to make sure the fuel lines when in the right spot on the carb, and I put in the new primer bulb, and bingo everything works great now!
