VMS Racing LIQUID FILLED 1 1/2" (38.1MM) O.D. mechanical 0-60 PSI fuel pressure gauge AND ADAPTER for the 2005-2010 Ford Mustang GT And Shelby GT500 with either the 4.6L or 5.4L engines. This comes with the VMS Racing CNC machined billet Aluminum hard anodized black fuel rail adapter for the 2005-2010 Mustangs with the V8 engines. The adapter has 2 outlets so you can put the gauge on one side and a use the other side for a myriad of things like: for nitrous fuel feed, for a fuel pressure gauge sender for a gauge that will be on the inside of the car etc... 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!
