FUEL SYSTEM / CARBURETION

4.12

Fuel Delivery System - Typical

The fuel system contains many components which directly affect fuel mixture and driveability. When performing

diagnosis or carburetor maintenance, the entire fuel delivery system should be inspected. The illustration below

shows parts of the system requiring periodic maintenance to ensure there is no fuel or air leaks present.

Fuel filters should be replaced at least once per season. More often if any contamination is suspected.

Fuel lines should be replaced every other season. More often if they become brittle or swollen. Fittings should

be inspected for cracks or leaks. Do not use pliers or other tools that may damage fuel lines when installing or

removing fuel lines.

Test run and check the fuel system for leaks any time parts are replaced. Verify that all lines are routed correctly

and away from any moving parts.

NOTE:

Some models use fuel filters are located inside the fuel tank. To inspect/replace filter:

Remove fuel cap.

Using a long clean wire, bend into a fish hook shape. Pull the fuel line that is inside of the tank up through

the filler hole.

Inspect filter on end of fuel pick up line. Replace if worn or clogged.

Red fuel line is the exterior line for

outside

the tank. The violet line is the interior line for

inside

the fuel tank.

They

cannot be interchanged!
NOTE: The violet line used inside the tank will fade and turn clear after a relatively short time. This does

not affect the function or durability of the line.

When replacing fuel line, be sure to use the correct color line for inside or outside the fuel tank. Also, be very

careful not to bend fuel line to a point of kinking it. If it becomes kinked, it

must

be replaced. Always inspect fuel

lines when replacing, or if carbs, carb racks, or fuel pumps are removed from chassis.
