Racor vacuum gauge designed to measure pressure and restrictions inside the fuel filter. A vacuum gauge can be used to help determine when a filter element needs replacing, indicated by the gauge displays excessive resistance. This fuel filter pressure gauge features a 2-1/2" diameter face, protected by a clear polycarbonate lens, for clear and easy readings. Instead of needle stops, this gauge uses an internal locking mechanism which prevents damage that would otherwise be caused by overpressure. Internal contamination is also tackled by seals around the fitting, the lens and the valve, to prevent any fluids from entering.

This panel mounted gauge measures -30 to 0 "Hg and features a 1/4" NPT thread. It is also supplied with 2 brass fittings and a mounting ring.
