Fuel Line Renewal on a 2012 Can-Am Renegade 800R

Buying the right hose is half of this job. Generic rubber tubing off a shelf is not interchangeable with what your 2012 Renegade 800R needs, because this Rotax V–twin machine is fuel injected. The pump sits inside the tank, the supply hose carries pressure whenever the key is on, and there is no petcock to shut off flow, which means the replacement has to be rated for injection pressure rather than gravity feed.

Choosing Parts and Laying Out Tools

Match the new hose to the original inside diameter, not to whatever looks close. Undersized hose will not seat on the barb, and oversized hose will not seal even with a clamp cranked down on it. With the correct line in hand, set the rest out on the bench:

  • Nitrile or rubber gloves plus eye protection
  • A sealed fuel–rated container and a shallow drain pan that fits under the frame
  • New clamps sized to the fittings, or a small assortment if you have not looked yet
  • Line–clamping pliers to pinch off flow, since this model has no petcock
  • A quick–connect release tool in case the tank outlet uses a locking coupler
  • A sharp hose cutter or fresh razor blade for a clean square cut
  • Rags, a small flat screwdriver, and sockets for the seat, side panels, and racks

Handling Gasoline Like It Deserves

Gasoline vapor is denser than air, so it drops to the floor and spreads outward instead of rising and dissipating. That single fact should shape your setup. Work outdoors when weather permits, or with the shop door open all the way and a fan pushing air across the floor rather than over the bench. Extinguish pilot lights on a water heater or furnace, unplug battery chargers, and keep grinders and torches out of the space entirely. Wear gloves for the whole job, because fuel strips the natural oils from skin fast, and change any clothing that gets soaked instead of working in it.

Why the Original Hose Is Past Its Prime

Fuel line ages on a calendar rather than an hour meter. The plasticizers that keep the rubber flexible gradually migrate out of the compound, and the wall stiffens until it can no longer flex without cracking. Heat from the V–twin drives that transition forward, and the vibration and frame flex a Renegade absorbs on rough ground focuses the damage where clamps grip the hose.

Climate and fuel chemistry finish the job. Dry, arid conditions draw moisture out of the hose wall, hardening it from the outside and leaving a chalky, finely cracked surface years earlier than a humid region would. Ethanol–blended gasoline goes after the inner liner, softening it and depositing gum, which is worst when the quad sits idle between seasons with old fuel still in the line. Both mechanisms run quietly, so a hose that looks fine can already be shedding material into the fuel it carries.

Symptoms That Should Get Your Attention

The most common early sign is a gasoline smell around the tank that is strongest in the minute after shutdown, while the circuit still holds pressure. Watch also for fuel wetness or a small puddle appearing on the skid plate after the machine has been parked, and for a ring of caked dirt at a fitting where seepage has trapped dust. Physically, check the hose for fine cracking, a hardened glassy feel, or a permanent flat groove at each clamp.

Performance tells you the rest. Bogging under load, a lean stumble at higher rpm, or hesitation that mimics running out of gas all point at compromised delivery, and unusually long cranking after an overnight sit means pressure is bleeding down. Since a pressurized leak often atomizes rather than dripping, treat a persistent fuel odor as real even with nothing visible on the floor.

Removal and Installation Step by Step

Depressurize the system before touching a fitting. Pull the fuel pump fuse or relay, crank the starter until the engine stalls from lack of supply, switch the key off, and disconnect the battery negative cable. Remove the seat and enough bodywork to see the tank outlet and follow the hose to the throttle body.

Slide the drain pan into place and cover the first joint with a rag, because residual fuel remains in the hose after pressure is gone. Push worm or spring clamps well back along the hose before disturbing the fitting. On a quick–connect coupler, press the locking tabs squarely and pull the collar straight off without side leverage, since plastic of this age cracks readily. Varnish often bonds the hose to its barb; break that with a gentle twist, or slit the hose lengthwise and peel it off rather than risking the fitting. This is a 4x4, so the line passes front differential hardware and additional frame crossmembers, and a couple of clips sit in tight quarters. Photograph the routing before the old hose is fully free.

Cut the new hose to the same length as the old one and push each end fully onto its barb until it bottoms out, working dry. Keep grease, oil, and silicone entirely off the fittings; lubricant on a sealing surface is how pressurized fuel escapes past a clamp. Soften a stiff hose end in hot water for thirty seconds instead. Set the new clamps just behind the raised bead at 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 by design. Reseat the hose in every original clip so it stays clear of exhaust heat and the front driveline.

Confirming It Holds

Refit 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 hose while the surrounding area is still dry, which makes even a slow weep easy to spot. Wipe both joints with a clean rag and study them under good light, then start the engine and inspect again at idle for several minutes. Once the connections stay dry, reinstall the plastics and the seat. Keep in mind that the filter on this injected 800R is built into the in–tank pump module rather than sitting inline, so continued fuel starvation after a clean hose install means the next step is inside the tank.
