Replacing the secondary filter
n Close the fuel cock for the primary filter (B).

engine does not run unevenly or stop due to air bubbles. Do not fill the secondary fuel
filter with fuel before installation. The fuel would not then be filtered and could be con-
taminated. Contaminated fuel increases the wear on the components of the fuel sys-
tem.
