Briggs & Stratton Fuel Filter – 845125

Product Details & Features

Keep your Briggs & Stratton engine’s fuel system clean and running efficiently with this genuine Briggs & Stratton inline fuel filter (Part 845125) — a key maintenance component engineered to protect your carburettor and fuel system from harmful debris and contaminants. 

This OEM fuel filter 845125 is part of Briggs & Stratton’s Extended Life Series, featuring a compact inline design that fits standard ¼″ (6.35 mm) fuel lines and is ideal for space‑limited engine bays. With a 30‑micron filtration rating, it effectively traps fine particles before they reach the carburettor, helping maintain smooth fuel flow and reliable engine performance. 

Key Features:

• Genuine Briggs & Stratton Part: Made to OEM quality and specifications for proper fit and dependable operation. 

• 30‑Micron Filtration: Helps remove dirt, rust and debris before they can enter the carburettor or fuel pump, reducing the risk of clogging and poor running. 

• Translucent Body: Clear housing lets you see fuel condition and easily check filter status at a glance. 

• Easy Inline Installation: Designed for straightforward replacement on compatible Briggs & Stratton engines with push‑fit barb connections. 

• Compact Size: Approximately 3‑1/2″ (88.9 mm) long with a 1‑1/8″ (28.6 mm) outer diameter, making it suitable for a range of petrol‑powered outdoor equipment.

Why It Matters:
Fuel cleanliness is critical for reliable engine starts, smooth running and long‑term durability. Over time, even small amounts of debris in fuel can lead to carburettor blockages, rough idling, hard starting and increased wear. Replacing old or clogged fuel filters with this genuine Briggs & Stratton 845125 helps maintain consistent fuel delivery and protects vital engine components — especially in dusty conditions or when using stored fuel.
