Overview

The SeaSierra Boat Marine 3/8 Inch 10MM Universal Rubber Hand Fuel Line Primer Bulb is a compact, dependable tool designed to prime fuel lines by hand. It moves fuel from the tank to the engine, supporting reliable fuel flow during starting and warm‑ups without needing powered pumps. The rubber body provides a soft, tactile grip that eases handling in damp conditions and tight spaces around the engine compartment.

Whether you are dockside, preparing for a day on the water, or performing routine maintenance, this primer bulb offers a practical solution for managing fuel delivery on outboards. Its universal fit and robust construction are meant to simplify replacements and help you stay prepared for common priming tasks on a variety of vessels.

Universal compatibility

  • Fits many marine brands including Yamaha, Mercury, Johnson, Evinrude, OMC, Honda, and more
  • Uses a standard 3/8 inch (10mm) inner diameter hose for broad compatibility
  • Designed to replace common tank‑to‑engine connections in many outboard systems

What you get in use

  • Manual priming delivers fuel toward the engine with each squeeze, supporting smoother starts
  • Flexible rubber body resists bending and kinking in cramped spaces on boats
  • Compact footprint helps keep deck and bilge areas organized
  • Durable construction, with a care note to avoid prolonged direct sunlight and harsh environments to extend life

Quick start tips

  1. Inspect hoses and clamps for wear before use
  2. Attach the bulb between the fuel tank outlet and engine fuel line
  3. Prime by squeezing several times until you feel firm resistance, then start your engine

Care and storage: This rubber primer bulb should be protected from direct sun and extreme heat when not in use. Store in a cool, dry place to help preserve flexibility and performance over time. The SeaSierra primer bulb is designed to be a practical, easy‑to‑use component for many outboard fuel systems, offering a straightforward way to assist fuel delivery without added equipment.
