Fuel Line Removal and Replacement: 2021 Can-Am Renegade 570

Take a close look at the hose feeding your 2021 Renegade 570 the next time the seat is off. Fuel line is a wear item, and the difference between a hose you can trust and one that is about to split is often just a few years of heat cycles. This quad runs a fuel injected Rotax single, so the pump sits inside the tank, the supply hose stays pressurized whenever the ignition is on, and no petcock exists to shut off flow before you start.

What Injection Changes About This Job

On a carbureted quad the sequence is simple: close the valve, drain the float bowl, pull the hose. The 570 gives you none of that. Its electric pump builds pressure through the line to the throttle body the instant the key comes on, and that pressure sits in the hose after shutdown. You will encounter either barbed fittings with clamps or self locking quick connect couplers depending on where you are in the run, and the fuel filter is part of the in-tank pump module rather than an inline element you can swap on the visible hose. Every step below assumes pressure has been relieved first.

How Fuel Hose Deteriorates

Two processes run in parallel. Externally, the plasticizers that make rubber flexible slowly escape under years of heat, fuel exposure, and air, leaving material that is stiff and brittle. Once it cannot flex, ordinary vibration and heat cycling from the engine work surface checking into cracks, typically starting at bends and at the fitting ends where stress concentrates. Dry climates hasten the change by continuously drawing moisture out of the hose wall.

Internally, ethanol blended gasoline pulls water into the fuel and chemically attacks the inner liner, which softens into a tacky layer and begins shedding particles toward the injector. A Renegade that spent a long stretch parked with stale fuel in the line can be significantly degraded inside while looking perfectly presentable outside. That mismatch is why calendar age deserves as much weight as a visual check.

The Early Warning List

  • A gasoline puddle or damp smear beneath the tank area after the quad has been parked
  • Persistent fuel odor near the tank, at its worst in the minutes right after shutdown
  • Hairline cracking, crazing, or a chalky bloom on the hose surface, worst at tight bends
  • A hardened section that does not spring back when pinched between finger and thumb
  • Bogging under load, lean surging, or an engine behaving as though the tank is nearly empty
  • A ring of caked dirt at a fitting, left behind where fuel seeped and evaporated repeatedly

Because the circuit is pressurized, a pinhole can atomize fuel completely and never leave a drop on the floor. Treat a strong smell as a real finding even without visible evidence.

Preparation and Handling Fuel Safely

Collect gloves, a sealable fuel container, replacement hose rated for injection pressure in the correct inside diameter, a clamp kit, line clamping pliers to substitute for the missing fuel valve, a quick disconnect release tool if needed, a razor knife, sockets for the seat and plastics, and plenty of rags.

Then be honest about the hazard. Gasoline vapor is heavier than air and pools near the floor, where a furnace pilot, water heater, or spark from a power tool will find it. Open the garage door fully or roll the Renegade outside, keep the drain container capped between pours, and disconnect the negative battery cable so the pump stays inert while a fitting is open.

Taking It Apart

Remove the fuel pump fuse or relay, then crank the starter until the engine dies, which vents the pressure held in the supply line. Key off, battery negative off. Pull the seat and side plastics to expose the tank, and follow the hose to the throttle body, noting each clip.

Slide a pan underneath and drape a rag over the first fitting you open, since a bled line still holds fuel. Move the clamps well back along the hose before disturbing anything, then twist each end gently to break the varnish bond instead of pulling hard. Quick connects release when both tabs are depressed squarely and the coupler is drawn straight off; side loading cracks aged collars. Any end that will not come free can be slit lengthwise with a razor and peeled off the barb.

This being a 4x4 machine, the line threads past front differential hardware and additional frame crossmembers that a two wheel drive quad does not have. Photograph every clip and clearance point before the old hose leaves the frame, because reproducing that path from memory is harder than it sounds.

Reassembly and Verification

Cut the new hose to the exact original length so it cannot chafe on the frame or foul the steering. Seat each end completely onto its barb, working dry, with no grease, oil, or silicone spray on the sealing surfaces — lubricant there is precisely what allows pressurized fuel to escape past a clamp. Warm water for half a minute softens a tight end enough to push on by hand.

Fit fresh clamps just behind the raised bead and tighten evenly. Where a self locking quick connect is used at the tank, push until you hear the click and then tug firmly to confirm it latched; that connection wants no clamp. Return the hose to all original clips, keeping clearance from the front driveline and from hot exhaust.

To verify, reinstall the fuse, Reconnect the battery, and cycle the key on and off several times so the pump pressurizes the line without the engine running. Wipe both joints and inspect closely, feeling as well as looking for dampness. Start the engine, idle it several minutes, and check once more before the plastics go back on. If fuel delivery still seems weak after a leak free install, the in-tank filter and pump assembly is the next place to look.
