Fuel System Fix: Renewing Your Weed Trimmer’s Lines and Filter 🌿

Your string trimmer, or “weed whacker,” is a workhorse, but its tiny two-stroke engine is extremely sensitive to fuel delivery issues. Over time, the clear lines inside and outside the fuel tank become brittle, crack, or—most commonly—get stiffened and dissolved by ethanol in modern gasoline.
