✓【No Fuel Tank Removal = Save Hours of Labor】Our professional MC400 Fuel tool lets you rebuild the check valve in 15-20 minutes without draining, removing, or disconnecting the fuel tank. Skip the $200+ dealership service and the mess of tank disassembly—get your Harley back on the road faster.
✓【Pro Installation Hacks to Avoid Leaks】Critical tips to ensure a perfect seal: ① Lubricate O-rings and tool tips with clean oil/fuel before use to prevent tearing. ② 100% clean the valve housing of old rubber debris (even tiny fragments cause seal failure). ③ New O-rings appear smaller than swollen old ones—they expand under fuel pressure for a tight, leak-proof fit.

Viton O-rings resist fuel degradation and extreme temperatures (-40°F to 400°F), outlasting generic rubber seals by 3x for long-lasting leak protection.
