Fuel Line Replacement on the 2014 Polaris Sportsman Touring 570
Shop parts for a 2014 Polaris Sportsman Touring 570 ATV.
Rubber does not last forever, and the hose carrying gasoline on your 2014 Sportsman Touring 570 has a harder job than most people realize. It sits close to a hot single-cylinder ProStar engine, flexes every time the chassis works over rough ground, and holds pressurized fuel whenever the key is on. Because the 570 uses electronic fuel injection, there is no petcock beneath the tank to shut off flow, and the pump and filter live inside the tank as one module. Knowing that before you pick up a wrench shapes the entire job.
What Actually Kills a Fuel Hose
Fuel line rubber is loaded with plasticizers that keep it soft and conformable. Those compounds slowly migrate out with age and heat, and the hose that once squished easily under your thumb turns stiff, glossy, and brittle. Once flexibility is gone, ordinary vibration from the Touring chassis starts opening hairline splits, usually right where the hose bends or where a clamp has squeezed it for years.
Climate accelerates the process. Machines that live in arid regions dry out from the outside faster, since there is no ambient moisture to slow the loss. Meanwhile, ethanol-blended pump gas works on the inside. When a Sportsman Touring sits unused for a few months with E10 in the system, the alcohol pulls in water and begins eating at the inner liner, leaving the hose soft internally while it hardens externally. Material shed from that liner heads straight toward the injector.
Symptoms That Should Get Your Attention
A tired line rarely fails all at once. Look and smell for the following:
- A small puddle or damp patch under the machine after it has been parked overnight
- A stubborn gasoline odor around the tank area, strongest shortly after shutdown
- Visible crazing, chalky texture, or a rock-hard section you can feel by pinching the hose
- An engine that bogs under load, stumbles on hard throttle, or behaves as though the tank is nearly empty
- Dirt caked into a dark ring at a fitting, which is dried fuel that has been weeping there quietly
Because the 570 runs a pressurized circuit, a small breach can atomize instead of dripping. That is why the smell often shows up long before any puddle does.
Gathering Parts and Making the Area Safe
Have everything within reach before a single fitting comes loose:
- Nitrile or rubber gloves, since gasoline defats skin fast
- A sealed container approved for fuel, plus a drain pan
- Replacement hose rated for injection pressure in the correct inside diameter, not generic low-pressure carburetor line
- Fresh clamps matched to the fitting style you find on your machine
- Line-clamping pliers, which take the place of the petcock a carbureted quad would have
- Rags, a small flat screwdriver, and sockets for the seat, plastics, and any tank hardware
Do this work outside or with the door fully open. Gasoline vapor is heavier than air and settles at floor level, so low ventilation matters far more than a cracked window overhead. Keep heaters, grinders, and anything with a pilot light well clear of the space.
Getting the Old Hose Out
Relieve pressure before touching a fitting. Pull the fuel pump fuse, crank the engine until it stalls, switch the key off, then disconnect the negative battery cable. Remove the seat and the side panels needed to expose the tank outlet and the run of hose heading toward the throttle body.
Slide the pan underneath and drape a rag over the joint you are opening, because even a depressurized line holds fuel that will run out. Worm-gear and spring clamps should be slid well back along the hose before you twist anything. If your Touring 570 uses a locking quick-connect at the tank, press the release tabs squarely and pull straight off — never lever a brittle plastic collar sideways. Break the varnish bond at each barb with a gentle twist rather than a hard pull, and if the hose refuses to let go, slit it lengthwise and peel it off the fitting.
Study the routing before the old piece is fully free. This is a two-up chassis with a longer wheelbase and On-Demand AWD hardware up front, so the line threads past more frame structure and driveline components than a short 2WD quad. Snap a photo of every clip and guide.
Fitting the New Line Correctly
Cut the replacement to the same length as the original. Extra slack chafes on the frame or drapes toward heat, and a hose cut short pulls at both fittings. Push each end fully onto its barb until it bottoms out against the shoulder, and do it dry. No grease, no oil, no silicone spray — lubricant on a sealing surface gives pressurized fuel a path to escape. If the hose is stiff, dip the end in hot water for a few seconds to soften it enough to slide home.
Set new clamps just behind the raised bead on each fitting and tighten them evenly, snug rather than crushed. Where a self-locking quick-connect is used, push until it clicks and then tug firmly to confirm the latch has engaged; that fitting needs no clamp at all. Return the hose to its original clips so it stays clear of the front driveline and exhaust.
Confirming the Repair Holds
Reinstall the fuse, Reconnect the battery, and cycle the key on and off several times without starting. Each cycle runs the pump and pressurizes the line, giving you a chance to inspect dry connections under real pressure. Wipe both joints with a clean rag, then look for beading or dampness. Start the engine, let it idle, and check once more, including with the front wheels turned lock to lock so the routing gets exercised.
One last note specific to this platform: the fuel filter on the injected 570 is part of the in-tank pump assembly rather than a serviceable inline unit. New hose will not cure a restricted filter, so if the machine still feels starved after a clean install, that module is the next thing to look at.
