FUEL LINE REPAIR
1. Do not use rubber hose within 4" of any part of the
exhaust system.
2. In repairable areas, cut a piece of fuel hose 4" longer
than portion of line removed.
NOTE: Fuel hose is 3/8" I.D. and fuel return hose is
1/4" I.D.)

portion of fuel pipe. Tighten clamps on each side of repair.
CLEANING FUEL SYSTEM
-
ALL SERIES
If trouble is due to contaminated fuel or foreign material
that has been put into the tank, it can usually be cleaned. If
tank is rusted internally, it should be replaced.
1. Disconnect battery negative cable and distributor feed
wire.
2. Drain fuel tank.
3. Remove fuel tank.
4. Remove fuel inlet filter at carburetor and inspect for
contamination. If filter is plugged, replace (leave fuel line
disconnected).
5. Locate tank away from heat, flame, or other source
of ignition. Remove fuel gage tank unit and inspect condition
of filter. If filter is contaminated, a new filter should be
installed upon reassembly.
6. Complete draining of tank by rocking it and allowing
fuel to run out of tank unit hole.
7. Purge fuel tank with steam or running hot water for
at least five minutes. Pour water out of tank unit hole (rock
tank to assure complete removal of water).
WARNING:THlS PROCEDURE WILL NOT

FUEL
VAPOR.
DO
NOT
ATTEMPT ANY REPAIR ON TANK OR
FILLER NECK WHERE HEAT OR FLAME
IS REQUIRED.
8. Disconnect inlet fuel line at pump and use air pressure
to clean fuel line and fuel return line (if equipped). Apply air
pressure in the direction fuel normally flows through line.
9. Use low air pressure to clean pipes on tank unit.
10. Clean filter on fuel tank unit, if required. Install fuel
tank gage unit (with new gasket) into tank and install tank.
Connect tank unit wires and all fuel lines, except pump to
carburetor line (see "Removal of Tank" for proper
procedure).
11. Connect a hose' to fuel line at carburetor; insert other
end of hose into a one gallon fuel can.
12. Connect battery cable. Make sure distributor feed
wire is disconnected.
13. Put six gallons of clean fuel in tank and operate
starter to pump two quarts of fuel into fuel can. This will
purge fuel pump.
14. Remove hose and connect fuel line to carburetor.
15. Connect distributor feed wire.
16. Check all connections for leaks.
FUEL TANK FILLER CAP
H Series
Removal
1. Rotate cap one-half turn counterclockwise to clear the
first set of tanks from the slots inside the filler neck.
2. This will allow any residual pressure to escape.
3. Pull the cap outward and rotate one-quarter turn
counterclockwise to clear second set of tangs, and remove the
cap.
4. To install, reverse this procedure.
If a fuel cap requires a replacement, only a cap with these
same features should be used. Failure to use the correct cap
can result in a serious malfunction of the system. Correct
replacement caps may be obtained from your dealer.
EVAPORATIVE EMISSION CONTROL
SYSTEM
Maintenance requirements demand only that the oiled
fiber-glass filter assembled in the bottom of the canister, be
replaced every 30,000 miles or 24 months. Under extremely
dusty conditions, more frequent attention may be required.
ACCELERATOR CONTROLS
GENERAL
The accelerator control system is cable type. There are
no linkage adjustments. Check for correct opening and
closing positions by operating accelerator pedal. If any
binding is present, check routing of cable.
ACCELERATOR CONTROLS
Refer to Fig. 6C-124 through 6C-136 for installation of
accelerator controls.
IDLE MIXTURE ADJUSTMENT
Idle mixture screws have been preset at the factory and
capped. Do not remove the caps during normal engine
maintenance.
Before suspecting the carburetor as the cause of poor
engine performance or rough idle, check ignition system
including distributor, timing, spark plugs and wires. Inspect
air cleaner, evaporative emission system, EFE system, PCV
system, EGR system, and engine compression. Also inspect
intake manifold, vacuum hoses and connections for leaks and
