Liquid Filled Pressure Gauge 0-15lb

The MR. GASKET Liquid Filled Pressure Gauge 0-15lb (Model 1563) is a mechanical analog fuel pressure gauge engineered for direct engine compartment monitoring. This 1-1/2 inch diameter liquid-filled gauge delivers accurate, full-sweep readings across the 0-15 PSI range, making it the standard choice for street performance engines, marine fuel systems, and custom automotive applications where fuel pressure verification is critical to reliability and tuning.

The liquid-filled design serves a specific technical purpose: the sealed glycerin-filled interior dampens needle vibration caused by fuel pump pulsation, eliminating the erratic gauge movement common to dry gauges on high-idle or racing engines. This stabilization makes pressure readings stable and readable even under aggressive driving conditions. The 1/8 inch NPT port accepts standard fuel line adapters and integrates easily into existing fuel systems. The white face provides excellent contrast visibility under varied lighting conditions, while the full-sweep needle movement enables quick visual confirmation of pressure status at a glance.

This gauge is purpose-built for fuel-injected engines, carbureted performance builds, and marine applications where monitoring fuel pressure prevents lean conditions, vapor lock, and fuel system failure. Street rodders, restoration shops, and performance tuners rely on MR. GASKET pressure gauges for their accuracy and resistance to vibration. The 0-15 PSI range matches standard fuel pump output on naturally aspirated engines; vehicles running forced induction or secondary fuel pumps may require the higher-capacity 0-30 PSI variant.

MR. GASKET has been the choice for engine builders and performance shops for decades, offering gauge solutions engineered for reliability in high-vibration environments. The liquid-filled construction and direct-mount design eliminate the guesswork in fuel system diagnostics.
