Replacement Elements
Optional Dual Layer Media Filter
Dual-layer media oers enhanced
dirt-holding capacity, extended
lter life, and ensures a more
complete removal of all size
contaminants. e R47S lter
replaces the R45S and provides
removal eciencies of 99.98%
(nominal) on 2 micron particles,
still much greater than the 50-90%
eciency of most single-stage
lters.

Vacuum Gauges
Vacuum gauges are available to
monitor element condition and as
the lter element slowly becomes
clogged with contaminates the
restriction (resistance to ow)
increases. e fuel pump still tries
to draw fuel (suction) but because
of restriction, less fuel is delivered
to engine and instead more air is
pulled from it (fuel de-gassing).
Results can cause engine to lose
power and eventually stall.
By installing a vacuum gauge in
the fuel system on the outlet side
of the lter, visual monitoring of
element condition is possible.
