Fueling the Vehicle
Gasoline is extremely flammable and can explode under certain conditions. Do not
add fuel while the engine is running or hot. If fuel is spilled in, on or around the
vehicle, wipe it up immediately. Flush out any fuel spilled in the vehicle with water
and allow it to drain out through the drain plug holes. Do not smoke when filling the
fuel tank.
Use clean, fresh, unleaded gasoline in all models of the ARGO. Minimum 87 octane fuel
is recommended. The use of Briggs & Stratton Fuel Stabilizer is also recommended
with each tankful.
Leaded gasoline can be used as a substitute fuel. However, if leaded gasoline is used, the
engine will require more frequent servicing.
Never use gasoline containing methanol or white gas since engine or fuel system damage
could occur.
All models of the ARGO are equipped with a 32 litre (7.0 Imp. Gal., 8.4 U.S. Gal.) “see-
thru” polyethelene fuel tank located underneath the driver’s seat. depending on loading
and driving conditions, an ARGO can be driven for 7 to 12 hours on one tank of fuel.
Verify your vehicle’s actual fuel consumption before attempting any long trips. Never
travel in remote areas or set out on long trips without a full tank of fuel and adequate spare
fuel stored in approved watertight fuel containers.
The fuel filler neck and fuel cap are located on the right side of the vehicle behind the
driver’s seat. Replace the fuel cap if fuel leakage occurs, or if moisture is detected in the
fuel.
Never fill the tank to the point where the fuel level rises into the filler neck. If the tank is
overfilled, heat may cause the fuel to expand and overflow through the vent.
Portable fuel containers may contain contaminants (dirt, water, etc.) that will cause engine
operating problems. Use only clean, approved gasoline containers.
After filling the fuel tank, be sure the fuel cap is replaced securely. Do not drive the
vehicle unless the fuel cap is properly in place.

Never use untreated gasoline that has been stored for more than 45 days. Stale
gasoline can cause deposits to form in the fuel lines and carburetor. These deposits
clog the fuel system and cause engine starting and operating problems.
When storing the ARGO for 45 days or more, use ARGO Part No. 127-77 Fuel
Stabilizer to treat fuel in the fuel tank and fuel containers.
Vented Fuel System - All Models
All ARGO models have fuel systems that are vented through a special hose connected to
the filler neck assembly that runs along the upper body to a fitting at the left rear.

Ensure that the vent line is not pinched, or becomes kinked between filler neck and
rear outlet fitting. Check the outlet fitting at the lower body occasionally for any
dirt or debris that may be plugging the venting system. Vehicle performance can be
drastically affected when fuel tank venting becomes restricted.

The filler necks of vehicles manufactured prior to CB14963, RB14945, BF10092,
SN10111 & S10112, may not be pulled through the upper body filler hole as shown
below. Filler necks in these earlier models have a small metal vent tube welded to
the filler neck, to which the vent tube is crimped. Pull the tank from the vehicle
along with the filler neck assembly until the vent line is visible and can be
disconnected from the filler neck tube

Inspecting the Fuel Tank and Fuel Line
Leakage in the fuel system is very dangerous! A spark or open flame can ignite
gasoline fumes, causing serious injury or death. Extensive vehicle damage will also
occur.
Regular inspection of the fuel tank and fuel line is essential to personal safety and good
vehicle performance. Inspect the fuel tank for:
•cracks or leaks
•loose or broken clamps
•loose connection in pick-up pipe

PH.(519)- 662-2840 FAX (519)- 662-2421 FS-7
•cracks, breaks or punctures in all fuel lines and hoses.
•cracked fuel filter casing
If any of these conditions exist, replace the affected component parts immediately.
Removing the Fuel Tank (6x6 Vanguards prior to S7304)
1. Drain the fuel tank.
2. Plug the filler pipe with a rag to prevent any foreign material from entering the tank.
7. Remove the fasteners securing the bench seat to the top of the fuel tank.
9. Disconnect the fuel line from the pickup tube.
13. Undo the gear clamp at the tank and pull the filler hose assembly free of the tank.
The vent tubing may remain attached to the metal neck assembly.
3. Remove the backrest. Locate and pry loose the 3 grey plugs in the upper
body behind the backrest.
4. Using a socket and extension, remove the 3 bolts and washers holding the backrest to
the upper body.
5. Lift the backrest out of the vehicle.
6. Remove the front floor pan.
8. Remove the seat cushion.
10. Slide the fuel tank and cage 2 or 3 inches toward the firewall.
11. Rotate the fuel tank 90 degrees.
12. Lift the fuel tank out of the seating compartment, sliding the fuel neck assembly out
of the upper body.
The vent tubing for the fuel system is attached to the metal filler neck section of the
filler neck assembly. Caution should be observed as not to damage the outlet nipple
welded to the metal neck assembly. Any bending or kinking of this small tube will
prevent the tank from venting causing serious performance issues later on.
14. Remove the tank & seat cage from the vehicle.

Installing the Fuel Tank (6x6 Vanguards prior to S7304)
1. Install any missing or torn pieces of cushioning to the fuel tank. There are 8 locations
that make contact with the fuel cage.
2. Assemble the cage and tank between the seat supports, at the same time reconnect-
ing the filler hose to the tank. As the fuel tank is completely installed, slide the fuel
neck intake assembly into the gas cap hole ensuring that the venting tube is vertical
to the vehicle body.
3. Tighten the gear clamp at the tank.
4. Reattach the fuel line to the pickup tube.
5. Fasten the fuel tank cage and seat to the seat support brackets. Tighten the bolts with
a socket and extension.
Insert the bolts squarely into the seat cushion and do not overtighten. Incorrectly
positioned and tightened bolts will strip or dislodge the thread inserts in the seat
cushions, resulting in a costly repair.
6. Reinstall the backrest.
7. Reinstall the front floor pan
All models of the ARGO are equipped with an in-line fuel filter (replacement fuel filter is
ARGO Part No. 125-64). On Conquest models the fuel filter is located in the fuel hose,
next to the fuel tank. On all other Argo models the fuel filter is located at the engine.
Replace the fuel filter after every 250 hours of operation or once a year. To replace the
filter, loosen the gear clamps with a standard screw driver and pull the rubber fuel lines
off of the filter. Install the new filter with the flow arrow pointing toward the engine.
Tighten the clamps securely. Start the engine and check for fuel leaks.
