Fuel Line Replacement on a 2002 Honda TRX250 Recon ES
Shop parts for a 2002 Honda TRX250 Recon ES ATV.
A 2002 Recon ES has had more than two decades to work on its fuel hose, and that is exactly the point. Even a low-hour example almost certainly needs this piece replaced, because the hose ages on the calendar whether the machine moves or not.
Two Decades of Rubber Fatigue
Every heat cycle from the air-cooled 229cc single drives a little more plasticizer out of the hose wall. Over twenty-plus years that adds up to rubber which has lost most of its elasticity, feels stiff and slightly glassy, and cracks at the bend nearest the carburetor. Sunlight slipping past the plastics contributes, and machines that spent their life in dry, low-humidity country reached that brittle stage long ago, since arid air steadily pulls moisture out of the compound.
The inner liner has been fighting a different battle. Ethanol-blended fuel arrived partway through this quad's life and it holds water in suspension, so any stretch of sitting with gas in the line let that mixture soften the rubber and leave gum behind. The result on an early Recon ES is often a hose that looks passable, feels hard outside, and is swollen and shedding inside.
The Electric Shift Recon Fuel Setup
The 2002 TRX250 Recon ES is carbureted. Its electric shift system changes how you select gears, not how fuel arrives — the engine still draws through a carburetor, so there is no fuel pump, no pressurized line, and no relay to pull before you start. A petcock under the tank gives you ON, OFF, and reserve, which is your fuel shutoff. Both hose ends use plain clamps rather than locking quick-connect couplers, and the carburetor float bowl empties through a drain screw on its underside.
This is a 2WD machine with a solid rear axle. With no front differential in the way, the hose runs a short and mostly open path from the tank outlet down to the carburetor. Expect twenty years of dirt in that area, though, so budget a few minutes to clean around the fittings before you open anything.
Signs the Line Is Overdue
On a machine this age, assume the hose is a wear item and inspect accordingly:
- Gasoline odor that lingers around the quad long after shutdown
- A wet ring or puddle beneath the left side of the engine
- Visible cracks, a chalky surface, or hose that holds its bent shape when released
- Dust caked in a band at a clamp, which marks a slow seep
- Bogging under throttle, a lean surge, or symptoms that mimic running out of fuel
Because delivery is by gravity, restriction is as damaging as leakage. A hose collapsed internally can idle the Recon ES all day and then starve it on a long pull, which sends plenty of owners chasing carburetor problems that never existed.
Tools, Parts, and Working Safely
Have all of this staged first:
- Fuel-rated hose matched to the original inside diameter
- New clamps, spring clip or small worm-gear style
- Gloves and eye protection
- An approved fuel container and a drain pan
- Line-clamping pliers, worth having since an aged petcock often seeps past OFF
- Screwdriver, sockets, razor knife, rags, and a work light
Gasoline vapor is heavier than air and gathers at floor level, where a water heater pilot or a battery charger can set it off. Work outside or with the door open at ground height, let the engine cool completely, and lay used rags outdoors to dry rather than sealing them in a can. On a valve this old, expect a dribble even with the petcock closed and keep the pan positioned for it.
Getting the Aged Hose Off
Turn the petcock OFF, remove the seat, and pull the left side panel. Slide the pan under the carburetor, open the float bowl drain screw, and let the bowl empty through its tube. Retract both clamps — on a 2002 machine the original spring clips may have lost tension entirely and can crumble, so plan on replacing them regardless.
Twist each hose end on its barb before pulling to break decades of varnish bond. Odds are strong that at least one end will refuse to budge; slit those lengthwise with the razor and peel the rubber off. Never pry at the petcock spigot, which becomes fragile with age and is far more expensive to replace than the hose you are removing. Note the clip locations and the hose clearance from the exhaust before the old piece leaves the machine.
Fitting the New Hose and Verifying It
Cut the replacement to the removed length. Push each end on dry until it seats fully against the fitting shoulder, with no grease, oil, or sealant anywhere on the barbs — lubricant there guarantees a seep and lets the hose creep off under vibration. Hot water for half a minute makes a tight end cooperate without any lubricant at all.
Set the new clamps just behind each bead and tighten them evenly. Close the drain screw, turn the petcock to ON, and watch both joints for a full minute while the float bowl fills. Wipe the area dry, start the engine, and check again at idle. Take a short ride and inspect a third time warm. While you are in there, look at the tank vent hose too — that piece is the same age and hardens the same way, and a blocked vent creates fuel starvation symptoms that will have you second-guessing your fresh line.
