Installation Notes
- Ensure the engine is off and the fuel supply is shut off. Disconnect the negative battery terminal for safety.
- Place an absorbent rag under the old connector to catch any residual fuel.
- Carefully release the locking mechanism and pull the existing connector off the engine fitting.
- Inspect the fuel line for signs of wear, cracking, or brittleness. Replace if necessary.
- Attach the new fuel connector to the 5/16" (8mm) fuel line, ensuring it is fully seated. A hose clamp may be used for added security.
- Firmly push the new connector onto the engine's male fitting until you hear or feel it 'click' into place.
- Restore the fuel supply, prime the fuel bulb until firm, and carefully check for any leaks around the connection.
- Once you have confirmed there are no leaks, reconnect the battery terminal, start the engine, and perform a final leak inspection.
Troubleshooting & FAQ
How do I confirm this connector fits my specific engine?
This part fits Suzuki 4-stroke outboards from 4 HP to 140 HP, generally from 1998 to 2011. Please review the detailed compatibility table to match your engine's model and year. It also directly replaces Johnson/Evinrude part 5032150 for models specifying that number.
Is this the connector for the engine side or the fuel tank side?
This is a male fuel connector designed for the engine side of the fuel line connection.
What are the signs of a failing fuel connector?
Common symptoms include visible fuel leaks at the connection point, a strong smell of gasoline around the engine, difficulty starting, engine stalling, or poor performance due to inadequate fuel flow.
The dimensions seem slightly different from my original part. Will it still fit?
Minor cosmetic differences are possible. The critical factors for fitment are the connection type (engine-side male connector) and the fuel line barb size (5/16"). If those match, it should function correctly. Always compare the product images to your existing part before purchasing.
