Sierra 18-8005EP-1 Primer Bulb 3/8" Marine Fuel Line

The Sierra 18-8005EP-1 is a 3/8" marine primer bulb designed to meet 2011 EPA regulations for low permeation fuel systems. This replacement fuel primer bulb is engineered for use with outboard motors and marine engines, providing reliable fuel priming in demanding saltwater and freshwater environments.

Key Features:

• EPA-compliant low permeation construction reduces fuel vapor emissions
• Superior resistance to UV rays, ozone, and ethanol-enhanced fuels
• Stainless steel spring and Viton ball check valves resist sticking and corrosion
• Standard 3/8" diameter fits most marine fuel line applications
• Durable construction maintains the reliable feel of previous generation bulbs

This primer bulb is designed as a direct replacement for worn or damaged fuel primer bulbs on boats, personal watercraft, and other marine applications. The advanced materials ensure long-lasting performance even when exposed to modern ethanol-blended fuels and harsh marine conditions.
