The new EM - USA17 Emission Engines Secondary Fuel Filters have a " DEEP " groove end cap
with a seal to fit on the new Fuel Filter Housings. Previous filters had a " SHALLOW " groove end
cap and will not fit nor seal properly on EM - USA17 Emission Engines Fuel Filter Housings. It is
also possible that metal debris may be created when trying to install the incorrect filter as seen in
the attached pictures here. The Secondary Filter is mounted in the forward position on the Fuel
Filter Housing. The Primary Filter is mounted behind the Secondary , or on the frame rail.
EM - USA17 Emission Engines require a 4 micron Secondary Filter.
