This little device helps to draw fuel into the carburetor, making it easier to start the engine, especially after it has been sitting for a while. Understanding its purpose helped me appreciate why I needed a reliable primer bulb.

When I bought my first fuel line primer bulb, I wanted something easy to install. I appreciated products that came with clear instructions or were designed to fit seamlessly without complicated modifications.

Before making my final decision, I always looked at customer reviews and ratings. Hearing from others who had similar experiences provided valuable insights. I found it helpful to read about how well a bulb performed over time and any issues others faced. This information often guided my purchasing decisions.
