The 570 X MR was built for deep water and heavy mud, and everything under the plastics on this machine leads a harder life than it would on a trail-only quad. Its Rotax single is fuel injected, which means an electric pump inside the tank keeps the supply hose pressurized any time the ignition is on, there is no petcock to shut off flow, and pressure lingers in the line after shutdown. Knowing that before you loosen a clamp keeps the job dry and controlled.

How the Rubber Comes Apart

Fuel hose depends on plasticizers to stay flexible, and those compounds slowly leach out over years of heat and fuel exposure. The hose stiffens, stops absorbing vibration, and begins to show surface checking that eventually penetrates the wall. On a mud machine that gets pressure washed regularly and cycled between hot engine temperatures and cold water, the swings are more severe than average and hardening tends to arrive sooner.

Climate contributes as well. Quads stored in dry, low humidity air lose moisture from the hose wall continuously and go brittle earlier. Ethanol blended gasoline attacks the opposite surface, drawing water into the fuel and degrading the inner liner into a soft layer that sheds material toward the injector. An X MR that sat with stale E10 in the line for months can be well compromised inside while the exterior still looks acceptable.

Symptoms on a Machine That Lives in the Muck

Diagnosis takes a little more care here because mud hides evidence. Wash the underside down and let it dry before you go looking. Then check for:

  • Fresh gasoline pooled on the skid plate or dripping onto clean floor after the quad has been parked
  • A fuel smell around the tank that persists, strongest in the first minutes after shutdown
  • Cracking, crazing, or a chalky film on the hose, worst at bends and right at the fittings
  • A hardened section that stays compressed instead of springing back when pinched
  • Bogging under load, a lean stumble on hard throttle, or the engine acting starved for fuel
  • A crusted ring of dirt at a fitting where seeping fuel has repeatedly wet and dried the grime

On a pressurized system a pinhole may atomize entirely and never form a drop, so trust a strong smell even when nothing is visibly wet.

Preparation, Parts, and Ventilation

Lay out gloves, a lidded fuel container, hose rated for injection pressure in the original inside diameter, new clamps, line clamping pliers to substitute for the fuel valve this model does not have, a quick disconnect release tool if your tank fitting is a coupler, a razor knife, sockets for the seat and body panels, and plenty of rags.

The ventilation point is real. Gasoline vapor is heavier than air and settles toward the floor, where a furnace pilot, water heater, or spark from a power tool can reach it. Open the overhead door completely or work outdoors, keep your drain container capped between pours, and disconnect the negative battery cable so the pump cannot energize while the system is open.

Bleeding Down and Removing the Line

Pull the fuel pump fuse or relay, then crank the engine until it stalls from fuel starvation. That single step relieves the pressure sitting in the hose. Turn the key off, disconnect the battery negative, and remove the seat and side plastics to reach the tank and trace the hose to the throttle body.

Position a catch pan and cover each fitting with a rag before you open it, since even a bled line holds a slug of fuel. Slide clamps well back along the hose first, then twist each end gently to break the varnish bond rather than pulling hard. Quick connects release when both locking tabs are pressed squarely and the coupler is drawn straight off; prying sideways cracks plastic that has aged in heat and been washed repeatedly. Where an end refuses to release, slit the hose lengthwise and peel it away from the barb.

Photograph the routing. This is a 4x4 chassis with an extra tall stance and snorkeled intake plumbing, so the fuel line shares space with front differential hardware and additional frame bracing that a two wheel drive quad does not carry. Getting the new hose back through the right clips and clearance points is much easier with pictures on hand.

Installing the New Hose

Cut the replacement to the same length as the original. Extra hose will lean on the frame or foul the steering and chafe through, which is the last thing you want on a machine that spends time submerged. Push each end fully onto its barb until it seats against the shoulder, working completely dry. No grease, no oil, no silicone spray on the fittings – a lubricated sealing surface is the classic cause of a leak that turns up a week later. Hot water softens a stubborn hose end enough to slide on by hand.

Place fresh clamps just behind the raised bead on each fitting and tighten them evenly. If your X MR uses a self locking quick connect at the tank, push until you hear the click and then pull firmly to confirm the latch engaged; that joint needs no clamp. Return the hose to every original clip, keeping generous clearance from the driveline and from hot exhaust surfaces.

Leak Check and Final Assembly

Reinstall the fuse, Reconnect the battery, and cycle the key on and off five or six times without cranking. Each cycle brings the pump up and pressurizes the circuit while everything is still dry, which is the easiest condition in which to spot a weep. Wipe both joints, then inspect and run a fingertip around each one. Start the engine, let it idle several minutes, and check again as it warms before the plastics go back on.

Worth noting on this platform: the fuel filter is part of the in-tank pump assembly rather than an inline unit on the visible hose, so a plugged filter will not be solved by fresh line. If the X MR still feels short on fuel after a clean, leak free install, that module is the next thing to investigate.
