Technical Specifications

Package Contents

• 1 x Fuel Line Assembly with Primer Bulb (JLM-17600)
• 2 x Connector fittings for 1/4" (6mm) fuel line

Installation Guide

1. Safety First: Ensure the engine is turned off and has cooled down completely. Work in a well-ventilated area away from any sparks or open flames.
2. Disconnect Old Line: Carefully disconnect the existing fuel line from both the engine and the fuel tank. Have a rag ready to catch any residual fuel.
3. Attach New Line: Connect the new fuel line assembly to the fuel tank and the engine, making sure both connector fittings are firmly seated to create a secure, airtight seal.
4. Check Flow Direction: Locate the flow direction arrow on the primer bulb. This arrow must point towards the engine for the fuel to flow correctly.
5. Prime the System: Squeeze the primer bulb repeatedly until it feels firm. This action draws fuel from the tank and fills the line.
6. Inspect for Leaks: Once the bulb is firm, thoroughly inspect all connection points and the entire length of the fuel line for any signs of fuel leakage before attempting to start the engine.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
A: This fuel line is a universal fit for most outboard motors, RVs, and small engines that use a 1/4 inch (6mm) inner diameter fuel line. It serves as a direct replacement for Yamaha part numbers 6Y1-24306-55 and 61J-24306-04 for 6mm applications. Always measure your existing fuel line's inner diameter to ensure compatibility.

Q: What is the difference between this and an OEM fuel line?
A: This is an aftermarket part designed to meet or exceed OEM specifications. It is made from high-quality, low-permeation rubber to prevent fuel evaporation and is fully compatible with modern ethanol-blended fuels, similar to original equipment.

Q: How often should the fuel line be replaced?
A: We recommend inspecting your fuel line assembly at least once a year for any signs of wear, such as cracking, brittleness, hardening, or swelling. Replace it immediately if you discover any damage, fuel odor, or active leaks.

Q: The primer bulb won't get firm. What's wrong?
A: First, ensure the arrow on the primer bulb is pointing in the direction of fuel flow (from the tank to the engine). An incorrect orientation is a common cause. Second, check that all connections are airtight. If it still won’t prime, there may be an air leak in the line or a faulty connection.
