This is the first high-volume pickup truck application to use an
all-plastic system to fill, store, and deliver diesel-exhaust fluid (DEF) to
the exhaust system to meet stringent diesel-emissions requirements. Multiple materials and molding processes are
featured on this system, 90% of whose components are polymeric, including the
plastic filler-pipe assembly (which requires no clamps), plastic supply module
with integrated pump, reverting valve, pressure sensor, heater, and filtration
unit. Additional plastic components in
the system include heated intake reservoir (with integral heater), level
sensor, filter, and temperature sensor.
The only other material that could have withstood the DEF fluid is
stainless steel, which would have been 7x heavier and cost 40% more.
