Features:
1. One-Way Valve System: The primer bulb features an integrated one-way valve, ensuring fuel flows only in one direction-from the fuel tank to the engine-preventing backflow and maintaining efficient fuel priming.
2. Ergonomic Design: It has a bulb shape that's easy to grip, allowing for easy manual fuel priming.
3. Flexible and Weather-Resistant: The materials are chosen for flexibility and resilience against environmental exposure, particularly in marine settings.

Functions:
The main function of the primer bulb assembly is to draw fuel from the tank into the fuel lines, effectively filling the line and removing air pockets. This allows the engine to start more easily, especially if the engine or fuel system has been idle. The primer bulb is critical for maintaining consistent fuel pressure and ensuring smooth fuel delivery to the carburetor or fuel injection system.

Maintenance Tips:
1. Regular Inspection: Check the primer bulb for cracks, stiffness, or leaks. Inspect both the bulb and the connecting hoses, as fuel leakage can indicate wear.
2. Avoid Over-Squeezing: Apply gentle pressure when using the bulb, as excessive force can damage the one-way valve inside.
3. Keep Connections Secure: Ensure that the hoses and clamps around the primer bulb are tight to prevent air leaks, which can impair fuel delivery.
4. Protect from Sunlight: Prolonged exposure to sunlight can cause premature aging of the rubber or plastic. Store in a shaded area or cover it when not in use for long periods.

Common Issues and Symptoms:
1. Valve Failure: If the one-way valve wears out, it may cause difficulty priming the fuel, leading to hard starts.
2. Hardening or Cracking: Exposure to ethanol fuel blends or environmental factors can cause the rubber to harden or crack, impacting the bulb's effectiveness.
