Fuel System And Carburetor

Fuel lines

• The carburetor contains a pump that draws fuel through the filter and up the fuel line. A hardened fuel line

that has cracked or does not seal tightly to a fitting may draw air into the line without leaking fuel out.

• Air leaks will reduce the fuel pumps ability to supply the carburetor.

• Clear line = fuel supply

• Blue line = return from primer to tank

• Black fuel lines = low permeation fuel line

NOTE: MTD started using low permeation fuel lines on some of the P25 series of engines in 2009. In 2012, all

MTD hand held engines will have the low permeation fuel line to comply with EPA guidelines. The low

permeation fuel lines can be identified by their black color.

IMPORTANT: Low permeation fuel lines can NOT be serviced separately. They must be replaced as part of

the fuel tank assembly.

Inspect the fuel lines:

• Are they cracked?

• Are they clogged?

• Are they brittle?

NOTE: If the answer to any of the above is yes, the fuel tank assembly must be replaced.

Fuel tank vent

The fuel cap is vented. Ensure that the vent is clean

and working properly. See Figure 5.8.
