New Fuel Line for Your 2019 Textron Alterra 570 XT

Owners keep the Alterra 570 XT around because it works. The winch, the cargo racks, and the 4x4 driveline get used, and the machine spends its life hauling instead of parked. That kind of duty puts hours on every rubber component under the plastics, including the hose feeding the throttle body. Since the 2019 570 XT is fuel injected, there is no petcock beneath the tank and no float bowl to drain; an in-tank pump keeps that hose pressurized, and the job starts with taking that pressure away.
The Aging Process Inside the Hose Wall
Rubber fuel hose is a consumable, not a permanent fitting. The plasticizer package that keeps it supple slowly cooks out under the heat of a hard-working 545cc single, and the hose stiffens a little more each season. Once it can no longer flex with chassis movement, hairline splits form at every tight bend. In dry climates the timeline shortens considerably, because low humidity draws moisture out of the rubber and hardens it from the outer surface inward until it feels almost like plastic.
The inside of the hose faces a different enemy. Ethanol in pump gas pulls water into the fuel and slowly breaks down the inner liner, leaving it swollen and soft while shedding fine debris toward the injector. When a 570 XT sits idle for months with that blend in the system, gumming and varnish have plenty of time to set up. The practical takeaway is that condition and age both matter: a hose can pass a visual inspection and still be crumbling from within.
Kit and Workspace
Set out the following so you are not walking away mid-job with fuel in the air:
- Rubber or nitrile gloves and safety glasses
- An approved fuel container plus a shallow drain pan
- Fuel-injection rated hose in the same inside diameter you pull off — ordinary carburetor line will not tolerate the pressure
- New clamps matched to the original style and a set of clamp pliers
- Line-clamping pliers to pinch the hose closed, since this model gives you no valve to turn
- A sharp razor knife, a pile of rags, and hand tools for the seat and body panels
Ventilation deserves real attention here. Gasoline vapor is denser than air, so it flows downward and gathers at floor level where a water heater pilot or a shop heater can reach it. Work outdoors when you can, keep the door fully open when you cannot, and stay away from grinders, torches, and open flame for the duration.
How a Bad Line Announces Itself
A hose on its way out usually leaves evidence:
- Fuel dripping onto the skid plate or standing in a small puddle beneath the frame
- A strong gasoline smell that lingers, often at its worst right after you shut the engine down
- Cracks, crazing, or a chalky surface on the hose, along with a hard spot that no longer compresses under your fingers
- Bogging under throttle, stumbling while towing or climbing, or symptoms that mimic a nearly empty tank
- Caked dirt forming a band at a fitting, which marks a slow weep that has been drying and collecting dust
With pressure in the line, a pinhole can atomize fuel and evaporate it before a drop ever hits the ground. Take the smell seriously even when nothing looks wet.
The Teardown
Start by bleeding down the system: pull the fuel pump fuse, crank until the engine stalls, turn the key off, and disconnect the battery negative cable. Pull the seat and the plastics that hide the hose run between the tank and throttle body. Slide the drain pan into position and lay a rag over the fitting you plan to open, because a depressurized hose still holds fuel that will run out the moment it separates.
Move each clamp well back along the hose before you disturb the joint. Quick-connect couplers want the tabs pressed evenly and a straight pull — levering sideways cracks collars that have been heat-cycled for years. Rotate the hose on its barb to break the varnish that has bonded it in place, and split a stuck end lengthwise with the knife rather than fighting it. Pay attention to the path as the old hose comes out. On this 4x4 chassis the front differential and driveshaft occupy space a two-wheel-drive quad leaves empty, so the line follows specific clearance points that need to be duplicated.
Fresh Hose Installation
Cut the new piece to the same length as the old one. Extra hose sags toward exhaust heat or rubs on frame welds, while a short piece leaves both fittings pulling against the barbs. Work each end on dry until it seats fully against the shoulder. Skip grease, oil, and silicone lubricant completely; a slick sealing surface is exactly how pressurized fuel finds its way past a clamp. Dip the hose ends in hot water for a few seconds if they need softening.
Place the new clamps behind the raised bead on each fitting and tighten them evenly, snug rather than crushed. If the tank side uses a self-locking quick-connect, push until the collar clicks and then tug to confirm engagement; that design seals without a clamp and adding one does no good. Route the hose back through every factory clip so it stays clear of the driveline, the winch wiring, and hot surfaces.
Last Checks Before You Ride
Reinstall the pump fuse, Reconnect the battery, and cycle the key on and off four or five times without cranking. The pump primes with each cycle, letting you inspect both connections while everything is dry and clean. Run a light-colored rag around each fitting, then start the engine and watch again at idle and under a few throttle blips. Several quiet, leak-free minutes should pass before the plastics go back on.
Finally, remember where the filter lives on an injected Alterra. It is part of the pump assembly inside the tank rather than an inline unit on the visible hose, so new line will fix a leak but not a restriction. A 570 XT that still stumbles under load after a clean install points you toward that in-tank module next.
