At Altus Scooter & Motorcycle Parts™, we're dedicated to keeping your adrenaline pumping on Taiwan's bustling streets or scenic routes. We're thrilled to introduce our latest product: the KTM Duke Fuel Pump Assembly. Compatible with the 2017-2025 KTM Duke 200, 250, 390, and RC390 models, this aftermarket essential ensures reliable fuel delivery for smooth performance. If your bike is experiencing starting issues, power hesitation, or inconsistent idling, this assembly is the solution to get you back on the road with confidence.

What is the KTM Duke Fuel Pump Assembly?

This in-tank EFI fuel pump assembly is a direct replacement for OEM parts like 90207088000, 93507088100, and aftermarket equivalents such as JP171800 or HFP series. It features a compact pump motor, integrated pressure regulator, fuel strainer/filter, and wiring harness with connectors. Built with durable white plastic housing, metal internals, and corrosion-resistant components, it includes a check valve to prevent backflow and is designed for high-vibration environments typical of street and sport riding.

Key physical highlights include:

Cylindrical white plastic body with mounting clips, inlet/outlet ports, and a blue wire for electrical connection.
Integrated strainer to filter debris and maintain clean fuel flow.
Lightweight and compact design, ethanol-compatible up to E10, engineered for over 100,000 miles of service.

How It Powers Your KTM Duke/RC

This assembly is the backbone of your KTM's fuel injection system, pumping filtered fuel from the tank to the injectors at consistent pressure for precise combustion. Mounted inside the tank, it works seamlessly with the ECU to provide on-demand flow, ensuring accurate fuel gauging via the integrated sender.

Here's how it enhances your experience:

Reliable Delivery: Steady pressure prevents lean mixtures or stalling, essential for the Duke 390's agile handling or the RC390's sporty dynamics.
Application Scenarios: Perfect for daily commutes on the Duke 200/250, spirited rides on the 390, or track days with the RC390, supporting 199cc-373cc engines.
Tough Build: Vibration-resistant and filtered against contaminants, ideal for Taichung's urban traffic or rainy conditions.

Common fixes include resolving low pressure (below 3.5 bar) that causes poor performance, as noted in service guides and rider experiences.
