⚡ At a Glance
- • Filtering Efficiency: Captures common fuel contaminants to help maintain a clean fuel supply
- • Best for: Owners of Mercury and Sierra outboards seeking compatible replacement filters
- • Not ideal for: Applications that require manufacturer-branded or metal-bodied filter assemblies
Compatible with several Mercury and Sierra fitments and constructed from sturdy plastic. Inline filtration supports injector health and helps maintain consistent fuel flow.
Protects injectors and engine operation - with inline contaminant capture
Inline filtration traps particulates and debris before they reach the fuel rail and injectors, preserving fuel flow paths. The filter media prevents large contaminants from passing downstream while maintaining feed pressure within normal ranges.
Cleaner fuel reaching injectors reduces the chance of blockages and helps the engine run more consistently. That protection reduces the risk of injector-related faults and keeps performance predictable on the water.
Fuss-free replacement - with precise sizing for existing hose clamps
Designed to match common hose diameters used on compatible Mercury and Sierra outboards, the filter fits into the fuel line inline and secures with existing clamps. No specialised tools or adapters are required for standard installations.
Quick swap-outs can be completed at the slip or in the garage, minimising downtime and keeping maintenance straightforward. Regular scheduled changes are simple and do not demand professional fitting.
Durable for marine use - with robust plastic construction
Manufactured from strong plastic that resists impact during handling and is less prone to corrosion than metal alternatives. The material choice keeps unit weight low while offering mechanical resilience in saltwater environments.
Lightweight, corrosion-resistant construction makes the unit easy to handle and store, while helping to avoid damage during routine maintenance. Longevity of the component supports dependable service intervals.
