Racor RK19667 Vacuum Gauge Bottom Mount 30 inHg 15 PSI

The Racor RK19667 is a dual-scale vacuum and pressure gauge designed for bottom mounting on diesel fuel filter/water separator systems. This essential diagnostic tool monitors filter condition by measuring vacuum levels during engine operation and can also measure positive pressure in fuel systems.

Key Features:

• Dual scale measurement: 0-30 inches of mercury (vacuum) and 0-15 PSI (pressure)
• Bottom mount configuration for clean installation through panel or mounting surface
• Color-coded dial face for easy reading of normal, caution, and filter change zones
• Durable construction designed for marine and automotive diesel applications
• Compatible with Racor fuel filter/water separator systems
• Helps prevent engine damage by indicating when filter replacement is needed

This gauge provides critical feedback about fuel filter restriction, allowing operators to maintain optimal fuel flow and replace filter elements before performance is affected. As filters become clogged with contaminants, the vacuum reading increases, signaling when service is required.
