Up for sale is a genuine, high-quality Parker Racor RK19669 Diesel Fuel Filter Restriction Vacuum Gauge. This mechanical monitoring instrument is the official current-production standalone replacement gauge engineered specifically to supersede older, discontinued legacy Racor gauge models including the RK 11-1676 and RK 11-1676E.

Primarily utilized on legendary Racor 500, 900, and 1000 Turbine Series diesel fuel filters/water separators, this gauge traces plumbing restriction levels in real-time. By eliminating guesswork on element swap intervals, this gauge helps you extract maximum life from your filter elements while safely preventing unexpected engine starvation or injection pump damage due to severe line clogs.

This upgraded design features a 2.5-inch polished stainless steel case and a shatterproof, diesel-resistant polycarbonate lens that outlasts old plastic housings.
