How to Swap the Fuel Line on a 2016 Can-Am Outlander MAX 650 DPS

Set Up the Space Before You Set Up the Tools
Fuel line replacement on a 2016 Outlander MAX 650 DPS is a straightforward repair with one genuinely hazardous ingredient. Gasoline vapor is heavier than air, which means it does not drift out an open window. It sinks, spreads along the floor, and pools in low corners where a water heater pilot, a furnace burner, or a portable shop heater can reach it long after the smell has faded at standing height. Work outdoors when you can. When you cannot, raise the garage door completely and put a fan on the floor pushing air out of the space, not recirculating it.
Wear gloves. Gasoline pulls the oils out of skin fast and carries additives worth keeping off your hands. Keep the fuel container capped between pours, disconnect the battery any time a line is open, and postpone grinding or welding to another day entirely. That is the whole safety brief, and it is worth following liteRally.
Confirming the Fuel System on This Machine
The Rotax V-twin in this Outlander is fuel injected. There is no petcock beneath the tank, no gravity feed, and nothing to turn off before you start. A pump submerged in the tank keeps the supply hose pressurized, and residual pressure lingers after shutdown, which is why line-clamping pliers belong in your tool pile and why the job begins with bleeding the circuit rather than closing a valve. The MAX chassis also stretches the frame for a second seat, giving the hose a longer path with more clips than a single rider Outlander uses, and the selectable 2WD and 4x4 driveline puts front differential hardware close enough to part of that path to define a clearance point or two.
Why Hoses Reach the End of the Road
The failure is chemical, and it comes from both directions. Externally, plasticizers that keep the rubber supple migrate out over the years. The hose grows stiff, quits flexing with the frame, and starts developing fine surface cracks that vibration from the twin pushes steadily inward. In dry country this progresses faster, because arid air keeps drawing moisture out of the hose wall.
Internally, ethanol blended fuel goes after the liner, and it does the most damage when a machine sits with fuel standing motionless in the hose for months rather than moving through it. The end result is a hose that is glassy outside and softening inside, shedding particles downstream toward the injectors while it still looks acceptable in the frame. That is why a hose this old earns replacement on age alone.
What Tells You the Line Is Done
- A puddle or damp streak of gasoline beneath the machine after it has been parked
- A strong fuel smell near the tank, most noticeable right after shutdown
- Cracking, a chalky cast, or a hardened section you can feel when you pinch the hose
- The engine bogging under load, hesitating on throttle, or acting starved when the tank is not empty
- A caked ring of dust at either fitting where fuel has seeped and dried repeatedly
Since the circuit is pressurized, a pinhole often sprays fine mist that evaporates before reaching the ground. A fuel odor with nothing wet under the machine still counts as a finding.
Removal, Start to Finish
Relieve pressure first: pull the fuel pump fuse or relay, crank the starter for a second or two until the engine dies or will not catch, turn the key off, and disconnect the negative battery cable. Then pull the seat and the plastics covering the tank outlet, and follow the hose forward to the throttle body, noting each clip and pass-through as you go.
Slide a drain pan beneath the joint you plan to break, drape a rag over the fitting, and separate it slowly, because standing fuel remains in the hose even after the pump circuit is bled. Loosen worm-gear clamps fully or slide spring clamps well up the hose before disturbing the end. Quick-connect couplers require the tabs pressed evenly and a straight pull; prying to the side snaps collars that have gone brittle from years of heat cycling. If varnish has bonded a hose end to its barb, twist gently to break it loose, and if that fails, slit the hose lengthwise and peel it away rather than risking the fitting itself. Take photos of the complete routing before the old hose comes out of the clips.
Your tool and parts list is short: gloves and eye protection, an approved fuel container, a wide drain pan, hose rated for injection pressure in the original inside diameter, new clamps in the matching style, a quick-disconnect release tool if the tank fitting is a locking coupler, line-clamping pliers, rags, a razor blade, and the drivers for the bodywork.
Installation and the Final Leak Check
Cut the new hose to the same length as the original. Extra length is not helpful; a long hose sags toward hot exhaust or rubs a frame edge until it wears through. Push each end onto its barb dry until it seats fully past the raised bead, and keep grease, oil, and silicone away from the fittings entirely, since lubricant on a sealing surface gives pressurized fuel a route to escape from under the clamp. Warm a tight hose end in hot water if you need help getting it seated.
Set the new clamps just behind each fitting bead and tighten evenly, snug rather than crushed. Where the tank side uses a self locking quick-connect, push until it clicks and then pull on it to confirm engagement; that connection needs no clamp. Reinstall the hose into every original clip and verify clearance with the suspension at rest.
Reinstall the fuse, Reconnect the battery, and cycle the key on and off five or six times without cranking. Each cycle pressurizes the line while the engine stays cold, which is the best condition for inspecting both joints with a flashlight and a clean white rag. Any dampness means reseat and reclamp before you continue. When it holds dry, start the engine, idle it several minutes, and check once more warm. One last note worth carrying with you: on this injected Outlander the fuel filter lives inside the tank as part of the pump module, not inline on the hose, so continued fuel starvation after a clean install points at that assembly rather than the line.
