#8 Standard Barrier Crimp In Fitting with GM Sensor

LS Swap GM A/C Pressure Sensor Kit – #8 Standard Barrier Hose (M10x1.25)

Achieve factory-level engine management in your LS swap with the ACK-002 Integration Kit. This kit is designed to bridge the gap between your aftermarket A/C system and the GM ECM/PCM. By installing this sensor into your high-pressure line, your engine controller receives the real-time data necessary to bump the idle when the compressor engages and trigger the electric cooling fans based on A/C system pressure.

Without this integration, LS-swapped vehicles often suffer from RPM dip or stalling at stoplights when the A/C is turned on, as the ECM cannot compensate for the sudden engine load.

Kit Includes:

• (1) Steel Crimp-In Fitting: Specifically engineered for #8 Standard Barrier A/C hose.

• (1) GM A/C Pressure Sensor: OEM-spec sensor with M10x1.25 metric threads.

Technical Specifications

• Fitting Material: Heavy-duty Steel for a reliable, leak-free crimp.

• Thread Pitch: M10x1.25 (Metric).

• Application: High-Pressure Discharge Hose (Compressor to Condenser).

• Control Type: Full ECM/PCM integration (Not a simple binary switch).

Is your hose #8 Standard Barrier?

Most aftermarket A/C systems (such as Vintage Air or Sanden-style setups) use #8 hose for the compressor discharge. To ensure this kit fits your application, please verify your hose dimensions using the table below:
