VMS Racing LIQUID FILLED 1 1/2" (38.1MM) O.D. mechanical 0-100 PSI fuel pressure gauge WITH the Honda/Acura fuel rail adapter. Gauge can be used as a fuel pressure, oil pressure, air pressure etc... gauge. Gauge will bolt on to a 1/8" NPT female port.
VMS engineers designed this gauge to be the ULTIMATE liquid filled gauge for many reasons:
1- PERMANENTLY SEALED UNIT: Unlike basically EVERY other 1 1/2" in line gauge on the market, the VMS Racing gauge is permanently sealed, the plug can not be removed and will not leak. It does not have a removable rubber plug on the back, which always leaks and can be a fire hazard! Removable, leaky rubber plugs are BAD IDEA!
2 - NICKEL PLATED FOR CORROSION RESISTANCE: Nickel plating prevents corrosion of the gauge, will look great for years to come!
3- VACUUM SEALED FOR ACCURACY: Gauge is vacuum sealed so that it will be minimally affected, or not affected at all by temperature changes. As you probably know, liquid filled gauges will vary the reading depending on the temperature, because of the expansion and contraction of the liquid inside the gauge. Since this gauge is vacuum sealed this issue is almost non-existent in these gauges!
