RK 32036   Vacuum restriction indicators monitor element condition as
the filter slowly becomes clogged with contaminants. As the
element gets dirty, restriction increases and less fuel is delivered
to your engine causing the engine to lose power and eventually
stall. By installing, a vacuum indicator in your fuel system,
visual monitoring of element condition is possible at a glance,
increasing fuel system troubleshooting efficiency, eliminating
guess work, and lenghtening element change interrvals.
