Critical Tuning Tool
Easily set or monitor the fuel pressure on your 1986-1998 Mustang GT 4.6L, 5.0L V8 with this BBK Liquid Filled Fuel Pressure Gauge & Fuel Rail Adapter. This gauge is ideal for setting fuel pressure with an adjustable fuel pressure regulator or it can aid in diagnosing fuel system issues.
Why Liquid Filled?
The glycerin filling in this gauge helps to dampen the movement of the needle. This makes it much more accurate because you typically set fuel pressure with the engine running, which causes a lot of vibration. A non liquid filled gauge would be all over the place in that situation.
Using the included adapter, you can attach this gauge to the factory schrader valve. This makes it simple to install and requires no special tools. Will work on many other applications as well, though additional fittings may be required.
