Is vauxhall diesel lift pump for 2.3 the same as a petrol pump?

No, the Vauxhall diesel lift pump for a 2.3 engine is not the same as the petrol pump. Diesel and petrol engines operate differently and require pumps designed specifically for their respective fuel types. Diesel pumps must handle higher pressures and different fuel characteristics than petrol pumps, which can lead to compatibility issues if used interchangeably. Always consult the manufacturer's specifications to ensure the correct part is used for each engine type.
