Sierra 20/21 Filter Kit

Protect your valuable marine engine with the ultimate defense against fuel contamination: the SIERRA 20/21 Fuel Filter Kit. Engineered for the harsh marine environment, this comprehensive kit is an essential upgrade for any boater looking to ensure reliability, performance, and longevity for their inboard or outboard engine. Dirty fuel and water are the leading causes of engine trouble on the water; don´t let a preventable issue ruin your day or lead to costly repairs. By installing this high-efficiency filter system, you provide your engine with a clean, dry fuel supply, allowing it to run at its peak potential every time you leave the dock. This kit is the professional´s choice for safeguarding sensitive fuel injection systems from the damage caused by water and microscopic debris.

Filters

Unmatched Water and Debris Filtration

The heart of this kit is Sierr´s industry-leading filter technology, designed to offer unparalleled protection. This system excels at two critical tasks: removing water and filtering out particulate contaminants.

Sierra fuel water separators are meticulously engineered to remove over 98.8% of emulsified water from your gasoline. Water in fuel leads to phase separation, corrosion of critical fuel system components, and poor engine performance. By effectively stripping this water out before it reaches your engine, the Sierra filter prevents these issues and protects your investment.

Furthermore, Sierr´s 10 micron filters are over 90% efficient at removing particles as small as 10 microns. These microscopic particles of dirt, sand, rust, and other debris can easily clog fuel injectors and carburetors, leading to engine hesitation, stalling, and a significant loss of power. With this advanced filtration, you can be confident that your engine is receiving the cleanest possible fuel for maximum efficiency and power output.

Technical Specifications

This filter kit is designed for high performance and broad compatibility, making it the ideal solution for a wide range of marine applications. All filters are engineered to flow at an impressive 90 GPH (gallons per hour), ensuring they can feed even the hungriest, high-horsepower motors without restricting fuel flow. This high flow rate guarantees your engine will never be starved for fuel, even under heavy load. The kit is highly recommended to prevent damage to sensitive inboard and outboard fuel injection systems, which are particularly vulnerable to contamination.
