Sierra

<p>For nearly six decades, Sierra has established itself as one of the marine industry's most trusted names in aftermarket engine and drive parts. Founded as a specialized marine parts manufacturer, Sierra has grown into a comprehensive supplier of replacement components, instrumentation, and accessories for both recreational and commercial boating applications. Operating from their 300,000-square-foot distribution center in Litchfield, Illinois, Sierra serves boat owners and marine technicians worldwide with an extensive catalog of parts engineered specifically for the harsh saltwater environment.</p><h3>Marine Engine Excellence</h3><p>Sierra's reputation was built on delivering precision-engineered internal engine components and drive system parts that meet or exceed OEM specifications. Their <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> provide critical sealing solutions for inboard and outboard motors, while their <a href="/7570-sierra-engine-complete-assembly-15341">engine complete assemblies</a> offer comprehensive replacement options for major overhauls. Each component undergoes rigorous testing to ensure reliability in demanding marine conditions, from corrosion resistance to temperature cycling performance.</p><h3>Instrumentation and Monitoring Systems</h3><p>Accurate instrumentation is essential for boat operators to monitor engine health and prevent costly breakdowns on the water. Sierra's comprehensive line of <a href="/7570-sierra-gauges-200483">gauges</a> includes everything from fuel pressure and temperature indicators to voltmeters and trim gauges, all designed with marine-grade materials that withstand vibration, moisture, and UV exposure. Their <a href="/7570-sierra-tachometer-gauge-1488">tachometer gauges</a> deliver precise RPM readings critical for optimizing engine performance and fuel efficiency. Supporting these instruments, Sierra's <a href="/7570-sierra-gauge-resistor-47908">gauge resistors</a> ensure proper signal conditioning and accurate readings across various sensor types and engine configurations.</p><h3>Expanded Product Portfolio</h3><p>In 2022, Sierra significantly broadened its scope beyond traditional marine engine parts to encompass a wider range of boating accessories and even outdoor power equipment components. This strategic expansion brought established marine brands like Shields and Moeller under the Sierra umbrella, creating a one-stop resource for marine maintenance and replacement parts. The company now offers fuel systems, electrical components, battery charging solutions, and NMEA electronics alongside their traditional engine parts lineup.</p><h3>Quality Backed by Industry-Leading Warranties</h3><p>What sets Sierra apart in the crowded aftermarket marine parts market is their commitment to standing behind every component they manufacture. Their warranty coverage extends beyond simple part replacement—it includes shop labor, haul-out fees, towing charges, and related incidental costs should a warrantied part fail. This comprehensive protection reflects the company's confidence in their manufacturing processes and quality control standards. For boat owners facing repairs far from shore or mechanics working on customer vessels, this peace of mind is invaluable. Whether you're maintaining an outboard motor, rebuilding an inboard engine, or upgrading your boat's instrumentation, Sierra's decades of marine industry experience and commitment to quality make them a reliable choice for keeping your vessel running at peak performance.</p>

Product Details

The Sierra 18-79957 VST Filter and Gasket Kit is a complete replacement kit designed for Yamaha four-stroke outboard engines. This kit provides essential maintenance components for the Vapor Separator Tank (VST) fuel system, ensuring clean fuel delivery and optimal engine performance.

What's Included:

  • One Sierra 18-79973 VST Filter
  • One Sierra 18-0717 Float Chamber Gasket

Key Features:

  • Direct OEM replacement for Yamaha part numbers 6C5-13915-00-00 and 6C5-14984-00-00
  • Filters debris and contaminants from fuel before reaching the high-pressure fuel pump

The VST (Vapor Separator Tank) is a critical component in fuel-injected outboard engines that removes fuel vapors and maintains consistent fuel pressure to the injectors. Regular replacement of the VST filter helps prevent poor performance, rough idling, and fuel delivery issues caused by contaminated fuel or ethanol deposits.

Compatibility: Yamaha F50, F60, F70, F75, F90, T50, and T60 HP outboard engines (2005-2014 model years). Always verify fitment with your specific engine model before ordering.

Fast easy and great prices!

I had never heard of Autoplicity until I started shopping for an exhaust. I didn't think I was going to find the one I wanted at a decent price. Not only did they have my exhaust at a screaming deal, they had it to my door in perfect shape in 6 days including the evening of purchase and a weekend. I'll definitely look at buying from them again.
