Direct Replacement Fuel Pump — OEM-Spec for Can-Am Defender HD5, HD8 & HD10 (2017–2021)
The Can-Am Defender is built for work — ranch operations, farm trails, hunting camps, and the kind of utility hauling that demands a machine you can count on day after day. Unlike sport UTVs, the Defender earns its keep through reliability and load capacity, not top speed. When the fuel pump starts to fail, you get the symptoms that kill a productive work day: hard starts in the cold morning, hesitation under load when hauling or towing, and the fuel starvation that shuts down a machine mid-task. This direct-fit replacement fuel pump (709000662) restores factory fuel pressure and flow across the full HD5, HD8, and HD10 lineup — 500, 800, 1000, and 500R engine variants — getting your Defender back to the dependable, work-ready operation it’s built for.
✅ Direct-Fit Compatibility
- Can-Am Models: Defender HD5, HD8, HD10
- Engine Variants: 500, 500R, 800, 1000
- Years: 2017–2021

- Suitable for ranch, farm, hunting, and heavy-duty utility applications
🔧 Built for Defender Work-Day Reliability
- OEM-matched fuel pressure & flow — factory-spec output for consistent engine performance under load, towing, and hauling conditions
- 100% new aftermarket — not rebuilt or remanufactured; starts with a full service life
- Full HD lineup coverage — one part number spans HD5, HD8, and HD10 across all four engine variants (500, 500R, 800, 1000)
- Built for utility demands — withstands the vibration, temperature extremes, and sustained load cycles of daily ranch and farm operation
- Reliable cold-start performance — consistent fuel pressure for dependable starts in cold early-morning work conditions
- No dealer markup — OEM-equivalent quality at aftermarket pricing
