Water Probe and Detection Kits

Vacuum and Compound (vacuum/pressure) gauges and related hardware is available to monitor element condition. As the filter element slowly becomes clogged with contaminants the restriction (resistance to flow) increases. The fuel pump still tries to draw fuel (suction) but because of this restriction less fuel is delivered to the engine and instead more air is pulled from it (fuel de-gassing). These results can cause the engine to lose power and eventually stall.

By installing a vacuum gauge in your fuel system (at the outlet side of the Racor filter) visual monitoring of element condition is possible at a glance. At the first indication of decreased performance, note the dial reading or apply the 'red line' decal provided with most kits. This will assist in knowing when to change the filter at the next interval.

Note: Intervals of element changeout may vary depending on fuel cleanliness. Always keep a spare Racor element on hand. Multiplex units other than FGX/MAX units may add a vacuum gauge to the outlet by installing a T-fitting.

Compound gauges are recommended for applications where pressure is occasionally present. These conditions are typically a result of 'head' pressure which is present in overhead fuel tank installations. Whatever the reason, compound gauges should be used because damage may result if a straight vacuum only gauge is used.

Liquid filled (glycerin) gauges are recommended for applications subject to additional vibration. The fluid helps to dampen the shock transfer to the delicate instrument movement within. Note: Internal pressure changes may result in external fluid leakage or failure of the pointer to return to zero with the engine off. If evident, clean leakage. Some models may be bled of excess internal pressure (and re-zeroed) by removing the top rubber plug momentarily. Make sure the plug is reinstalled properly. Take care not to push the plug into the gauge housing.

Use the guide below to find the correct gauge for your application.
