75126-02C EFI Fuel Pump Module
This EFI fuel pump module is designed for several Harley-Davidson EFI models from the early 2000s, including Electra Glide and Road Glide variants. It is best for riders performing a direct replacement on 2002–2005 touring bikes that require a compatible pump assembly to ensure proper pressure and flow.

Best for: Harley touring riders restoring or upgrading fuel delivery on mid-2000s EFI systems. Choose this if you want a plug‑and‑play replacement that aligns with original Harley configurations. A potential limitation is availability of exact factory-grade fittings for custom builds—verify hose clamps and mounting brackets before installation.

This pump is best for riders who want an economical, direct replacement with straightforward installation.
Best for: Honda GROM riders and light commuter bikes needing a dependable, compact EFI fuel pump. Better for: tight under-seat spaces where a larger pump would intrude. Caution: ensure the pump’s connector and mounting orientation match your bike’s wiring harness and fuel rail for a secure fit.
Fuel Pump for Honda VTX1800 and Related Models
This pump targets larger Honda V‑twin cruisers, including the VTX1800 series and compatible models like VFR800 and Silver Wing variants through 2013. It’s a suitable choice when upgrading fuel delivery on mid‑size to large displacement bikes that require robust fuel pressure stability across varied RPMs. The unit’s broader fit helps owners avoid misalignment on older EFI systems.
Best for: Honda VTX and VFR riders seeking a more stable fuel supply during aggressive throttle inputs. Choose this for reliable performance over a wider RPM range. Limitation: ensure compatibility with your specific year and model since some bikes use slightly different filter or return line configurations.

Fuel Pump for Yamaha YZF R1 and R6 Series
Engineered to fit Yamaha’s YZF R1 and R6 families, with additional matches to other YXR models and broader Harley compatibility, this pump provides strong performance across sportbike RPM ranges. It is best for sportbike riders who demand responsive throttle performance and dependable fuel pressure during high‑RPM operation. It can also suit multi‑model builds where a single pump supports several Yamaha platforms.
Best for: Yamaha sportbike owners needing a high‑demand fuel delivery solution. Choose this if you ride aggressively and require stable fuel pressure. Limitation: sportbike applications can be sensitive to flow characteristics; verify that the pump’s specifications align with your bike’s FP/pressure requirements.
