Swapping the Fuel Line on a 2009 Can-Am Outlander 800R XT

Shop parts for a 2009 Can-Am Outlander 800R XT ATV.

Before a single clamp comes loose, settle the most important question about your 2009 Outlander 800R XT: this machine is fuel injected. The 800R Rotax V-twin is fed by an electric pump that lives inside the fuel tank, and the hose running from that pump to the engine holds pressure whether the key is on or off. There is no petcock tucked under the tank on this quad, so the habit of reaching down to twist a valve to OFF simply does not apply. Understanding that up front keeps the job clean and keeps gasoline out of your face.

Confirming What You Are Actually Working On

The XT trim on the 2009 Outlander brings a winch, heavier bumpers, and a hitch, none of which change the fuel plumbing, though the winch harness and front bumper mounts do crowd the front of the machine a little. What matters more is the injection hardware. Your pump module sits in the top of the tank and carries the filter element and pressure regulator with it, which means the visible hose you are replacing is a pressure line, not a gravity feed. Expect a locking coupler at one or both ends rather than a plain barb with a worm clamp, and buy hose rated for injection pressure rather than the soft carburetor hose sold by the foot.

Why Rubber Stops Being Rubber

Fuel hose ages from two directions at once. On the outside, engine bay heat from the V-twin and years of ultraviolet exposure cook the plasticizers out of the wall, leaving the hose stiff and glassy instead of springy. Riders in dry, low-humidity country watch this happen faster, because there is nothing in the air to slow the loss of moisture from the rubber. Squeeze an original hose on a 2009 machine and it often feels more like conduit than tubing.

From the inside, ethanol-blended pump gas does its own work. Alcohol pulls water into the fuel and slowly breaks down the inner liner, so the bore swells, softens, and starts shedding fine debris toward the injectors. A quad that sits between rides suffers the most, because standing fuel has time to gum and varnish. The combination gives you a hose that looks fine from three feet away and is failing in both directions.

Symptoms Worth Catching Early

  • A gasoline smell around the tank and rear fenders that lingers after shutdown, while the system still holds residual pressure
  • Fine surface checking, a chalky gray cast, or a flattened section where a clamp has bitten in
  • A damp ring or dust-caked crust at a fitting, which is fuel weeping and drying repeatedly
  • A wet patch on the skid plate or a small puddle on the floor after the Outlander has sat overnight
  • Bogging under load, a stumble when you roll into the throttle hard, or the engine acting starved at higher rpm

Injected machines hide leaks better than carbureted ones. A pinhole on a pressurized line can atomize and evaporate before it ever drips, so trust your nose even when the floor is dry.

Gather This Before You Touch a Fitting

  • Nitrile or rubber gloves, since gasoline strips the oils out of skin fast
  • A sealed metal or fuel-rated container plus a shallow drain pan
  • Replacement hose in the original inside diameter, rated for fuel injection pressure
  • Fresh clamps matched to the fitting style you find, and a quick-disconnect release tool if your coupler uses one
  • Line-clamping pliers to pinch off any soft low-pressure section, because no petcock exists to shut flow
  • Basic sockets and drivers for the seat, side panels, and rack hardware, plus a pile of clean rags

Do this outdoors or with the garage door fully open. Gasoline vapor is heavier than air and settles at floor level, so ventilation down low matters far more than a cracked window overhead. Keep every heater, grinder, and pilot light out of the space, and let a warm exhaust cool before you start.

Getting the Old Hose Out

Relieve pressure first. Pull the fuel pump fuse or relay, crank the engine for a few seconds until it stalls or refuses to fire, switch the key off, then disconnect the battery negative cable. Strip the seat and the side plastics to expose the tank area and the hose run heading toward the throttle body. Slide your pan underneath and drape a rag over the first joint you open, since a depressurized line still holds a surprising amount of fuel.

Slide any spring or worm-gear clamp well back along the hose before you twist. For a locking quick-connect, press the tabs squarely and pull straight off; prying sideways cracks collars that have grown brittle over a decade and a half. Old hose usually bonds to its barb with varnish, so rotate it gently to break the seal rather than hauling on it. If it will not release, slit it lengthwise with a razor and peel it away, which protects the fitting at the cost of a hose you were discarding anyway. Photograph the routing before the last clip comes off. The Outlander is a 4x4 with a front differential and extra crossmembers in the way, so the line threads through more clearance points than a two-wheel-drive quad and it is easy to forget where it belonged.

Fitting the New Line

Cut the replacement to match the old piece exactly. Extra length looks harmless and then chafes on a frame tube or drifts toward the exhaust. Push each end fully onto its barb until it bottoms out, and do it dry. No grease, no oil, no silicone spray belongs on a fuel fitting, because any lubricant on the sealing surface gives pressurized gasoline a path to creep out past the clamp. If the hose is stubborn, dip the end in hot water for a few seconds to soften it. Set new clamps just behind the raised bead on each fitting and snug them evenly rather than crushing them. Where the 800R XT uses a self-locking coupler, push until it clicks and then tug hard to confirm it latched; that joint wants no clamp at all. Return the hose to every original clip so it stays clear of the driveline and hot pipe.

Proving It Before You Ride

Reinstall the fuse, Reconnect the battery, and cycle the key on and off several times without cranking. Each cycle runs the pump and pressurizes the circuit, letting you study both joints while everything is still dry. Wipe the fittings with a clean white rag and look for any darkening. Then start the V-twin, let it idle, and check again with the engine shaking the chassis. Give it several leak-free minutes before the plastics go back on. One last note specific to injection: the filter on your Outlander is part of the in-tank pump assembly, not an inline canister you can see. If fuel delivery still feels soft after a clean hose install, that module is the next place to look.
