Briggs & Stratton Primer Bulb - 694395

Product Details & Features

Give your mower or outdoor power equipment the quick, reliable start it needs with this genuine Briggs & Stratton primer bulb (694395) — a simple but essential fuel system component that helps your engine fire up more easily. 

This branded primer bulb is designed to work with a range of Briggs & Stratton small engines, especially Quantum, Sprint, and other petrol engines fitted to walk‑behind mowers and similar garden equipment. The bulb is made from fuel‑resistant elastomer that stays flexible season after season. When pressed, it draws fuel from the tank and pushes it into the carburettor, reducing the number of pulls needed to start the engine — especially from cold. 

Why It’s Useful:

• Improves Starting: Helps charge the carburettor with fuel before cranking, making cold starts quicker and more dependable. 

• Genuine OEM Part: Designed to Briggs & Stratton specifications for optimal fit, sealing and durability. 

• Durable & Fuel‑Resistant: Made from quality rubberized material that resists cracking and degradation from regular fuel exposure. 

• Easy Push‑Fit Installation: Direct replacement — no re‑tuning or special tools required, simply push into the primer housing to install. 

• Restores Performance: Replacing a worn, hardened or leaking bulb can help eliminate hard starting and reduce effort on pull‑start or electric‑start engines. 

Compatible With:
Many small Briggs & Stratton walk‑behind mower engines (e.g., 450E, 500E and various Quantum series) and other petrol‑powered garden machinery where part 694395 or its older equivalent 496115 is specified.
