Putting a New Fuel Line on a 2012 Can-Am Renegade 800R X XC
Shop parts for a 2012 Can-Am Renegade 800R X XC ATV.
Nothing derails a fuel line replacement faster than discovering mid–job that you have the wrong hose or no clamps. So start with the shopping list, informed by what the 2012 Renegade 800R X XC actually uses. This is an injected Rotax V–twin: pump inside the tank, pressurized supply hose to the throttle body, and no petcock anywhere to shut off flow.
Sourcing the Right Hose and Hardware
The hose has to be rated for fuel injection pressure. Low–pressure tubing intended for a gravity–fed carbureted machine will eventually balloon or weep on this system, and no amount of clamp torque compensates. Match the original inside diameter as well, since hose that is undersized will not seat on the barb and hose that is oversized will not seal. Alongside the line, plan on:
- New clamps in the correct size, or a small assortment if you have not examined the fittings yet
- A quick–connect release tool in case the tank outlet uses a locking coupler
- Line–clamping pliers, which do the job the missing petcock would have done
- Nitrile or rubber gloves plus eye protection
- A sealed fuel–rated container and a shallow drain pan that slides under the frame
- A sharp hose cutter or fresh razor blade for a square cut, rags, and sockets for the seat and panels
Setting Up a Workspace You Can Trust
Gasoline vapor is denser than air. It falls to the floor and spreads sideways, which is why ventilation at floor level is the part that counts and a high open window contributes almost nothing. Do this outside if the weather allows. Indoors, open the door completely and set a fan to move air across the floor and out of the space. Extinguish pilot lights on a water heater or furnace, unplug battery chargers, and put grinders and torches away for the afternoon. Keep gloves on the entire time, because fuel pulls the oils out of skin quickly, and change any clothing that catches a soaking rather than working in it.
Understanding Why Hoses Deteriorate
Time does most of the damage. The plasticizers that keep fuel hose flexible migrate out of the rubber over the years, and the wall goes from pliable to stiff to brittle. Once it stops flexing it starts cracking, and the clamped ends go first because they are compressed and immobile while heat from the V–twin cycles through them.
Two other factors set the pace. Dry, arid air draws moisture out of the hose wall and hardens it from the outside in, producing that chalky, hairline–cracked surface earlier than a humid climate would. Ethanol–blended gasoline works on the inner liner, softening it and depositing gum as it goes stale, which is at its worst when the XC sits between seasons with old fuel in the line.
Symptoms to Watch and Act On
The first clue is geneRally a gasoline smell around the tank, sharpest in the minute after shutdown while pressure remains in the circuit. Add to that fuel wetness or a small puddle on the skid plate after the quad has been parked, and a ring of caked dirt at a fitting where seepage has trapped dust. Squeeze the hose along its length: a permanent flat groove at a clamp, a glassy hard feel, or fine surface cracking all confirm it is finished.
Performance changes matter too. Bogging under load, a lean stumble at higher rpm, or hesitation that mimics a nearly empty tank point at poor delivery, while unusually long cranking after an overnight sit means pressure is bleeding away somewhere. Since pressurized leaks tend to atomize rather than drip, a fuel odor with no puddle is still a legitimate finding.
Removal and Installation
Relieve pressure before touching a fitting. Pull the fuel pump fuse or relay, crank the starter until the engine stalls from lack of supply, turn the key off, and disconnect the battery negative cable. Take the seat and enough bodywork off to see the tank outlet and follow the hose to the throttle body.
Slide the drain pan under the run and cover the first joint with a rag, because a depressurized hose still holds fuel that has to go somewhere. Walk worm or spring clamps well back along the hose before disturbing anything. On a quick–connect coupler, press the locking tabs squarely inward and pull the collar straight off with no side leverage, since plastic of this vintage cracks readily. Varnish commonly bonds an old hose to its barb; break that with a gentle twist, or slit the hose lengthwise and peel it off rather than pulling hard enough to damage the fitting. As a 4x4, the XC runs its line past front differential hardware and extra frame crossmembers, so photograph every clip and clearance point first.
Cut the new hose to match the original length and push each end fully onto its barb until it bottoms out, working dry throughout. Grease, oil, and silicone stay off the fittings entirely; a lubricated sealing surface is precisely how pressurized fuel escapes past a clamp. If a hose end is too stiff, thirty seconds in hot water solves it. Set the new clamps just behind the raised bead on each fitting and tighten them evenly, and where a self–locking quick–connect is used, push until it clicks and tug to confirm the latch, leaving that joint unclamped as intended. Reseat the hose in every original clip so it stays clear of exhaust heat and the front driveline.
Proving the Job Before You Ride
Reinstall the fuse, Reconnect the battery, and cycle the key on and off four or five times without cranking. Each cycle runs the pump and pressurizes the line while the area is still dry, giving you the clearest read on both joints. Wipe them with a clean rag, inspect under good light, then start the engine and check again at idle for several minutes before the plastics go back on.
Worth remembering as you finish: the fuel filter on this injected XC sits inside the tank as part of the pump module rather than inline on the visible hose. A new line addresses the hose alone, so if the engine still acts starved after a clean install, the assembly inside the tank is the next thing to examine.
