Nachman 07-238 1/4" Primer Bulb Assembly for Marine Outboard & Powersports

The Nachman 07-238 Primer Bulb Assembly is a compact 1/4" inline fuel primer designed for marine outboards, snowmobiles, ATVs, and small engines. This essential fuel system component allows you to manually prime the fuel line, ensuring quick starts especially in cold weather conditions.

Key Features:

• 1/4" inside diameter fits standard small engine fuel lines
• Built-in check valve prevents fuel from flowing back into the tank
• Easy installation - simply cut the fuel line and insert both ends into the primer bulb
• Durable rubber construction resistant to fuel and weather
• Compatible with ethanol-blended fuels
• Universal fit for marine outboards, snowmobiles, ATVs, and other powersports applications

This primer bulb assembly creates a vacuum when squeezed, drawing fuel from the tank through the fuel line and into the carburetor. Three to four pumps typically provide enough fuel to start most engines. The integrated check valve ensures fuel flows in one direction only, maintaining prime and preventing fuel return.
