Product Details

The Sierra 18-7841 is a replacement fuel pump diaphragm engineered for Yamaha two-stroke outboard motors. As a critical component of the engine's fuel lift pump system, the diaphragm flexes to create the vacuum necessary to draw fuel from the tank into the fuel bowl, maintaining consistent fuel delivery and proper engine performance.

A worn or failed fuel pump diaphragm can result in reduced fuel pressure, rough running, hard starting, or complete engine failure. Replacing it with a quality Sierra unit restores proper fuel system function and keeps your outboard running reliably on the water.

Key Features:

  • Direct replacement fuel pump diaphragm for Yamaha outboard motors
  • Meets or exceeds OEM quality standards
  • Replaces Yamaha OEM part number 6J8-24471-00-00
  • Engineered for durability in harsh marine fuel system environments
  • Part of Sierra's extensive line of over 6,000 marine replacement parts

OEM Cross-Reference:

  • Yamaha Outboard: 6J8-24471-00-00

Sierra International is a trusted name in marine aftermarket parts, producing components engineered to meet or exceed original equipment manufacturer specifications. The Sierra 18-7841 is a cost-effective solution for maintaining your Yamaha outboard's fuel system without sacrificing quality.

Thank you

Great service

Quick and easy to order. Unsure of how soon I will receive shipment.

I received my Borgeson steering shaft today for my 1990 dodge 1st gen. This is where I found the lowest price for the product. I was also very pleased in the speedy delivery. I will definitely use this company again.

Im very satisfied with how fast i received my product from Autoplicity! The whole process was hassle free. If you looking for quality product for a great price than i would recommend Autoplicity!

I was trying to locate a hi volocity radiator fan and for it at Autoplicity at a very good price. The item was shipped fairly quickly concidering it most likely had to come from the manufacturer. Thanks for your help.
