Description
A strong fuel pump is vital for performance on a V-twin Hyosung. The original Mikuni pumps are aging, and diaphragm failures lead to fuel starvation, especially at high speeds. This replacement part ensures consistent, reliable fuel pressure, allowing your engine to get the precise amount of fuel it needs, whether you are commuting in the city or touring the EU motorways.
💎 Built for E5 Fuel Longevity
We focus on material quality. The internal diaphragms are built with modern, ethanol-resistant compounds to withstand UK E5 fuel for maximum lifespan, justifying the premium price point over cheap eBay alternatives.
| Consistent Flow Rate Solves fuel starvation issues. |
Durable Housing Resists weather and vibration. |
| OEM Reference Matches 15100HG5100 spec. |
Easy Swap Uses standard vacuum lines. |
📜 Confirmed Fitment Guide
📅 YEARS: Generally covers 2001–2009 (some 125cc models up to 2017).
❌ WILL NOT FIT: Any Fuel-Injected (EFI) models (These use an electric pump inside the tank).
A common failure point is the vacuum tap (petcock). If your tap is slow, the new pump won’t fix it. View the Vacuum Tap replacement here to diagnose the issue properly.
🔧 Install Tips
- Check Vacuum Lines: A new pump is useless if the vacuum line from the engine intake has a crack. Check all your rubber lines for perishing.
- Use E5 Fuel: The UK government advises E5 fuel for carburetted bikes. The extra ethanol in E10 will perish your fuel lines and internal pump O-rings faster. Stick to E5 where possible.
