Fuel Pressure Test Gauge
The J-44321-1A is stored in the J-44321-A fuel pressure test kit. All future kits will include a 100psi gauge. This is a higher pressure 100psi gauge to replace the current 60psi gauge. The higher pressure fuel delivery systems in current models require using this new gauge. The J-44321-1A gauge is used during fuel pressure service procedures, where the J-44321 is referred to in the service manuals. Refer to the service procedures for additional usage information.
