Z22YH High Pressure Fuel Pump – Complete Disassembly & Reassembl

In this video I show the COMPLETE disassembly and reassembly of a Z22YH high-pressure fuel pump. https://www.ebay.co.uk/itm/168145796120 Important: this video focuses only on the fuel pump itself. The pump is already removed from the engine — I do NOT show removal from or installation onto the car. I made this video because I couldn’t find one clear guide that shows the full pump teardown and rebuild from start to finish. The information was spread across 5–6 different videos in 3–4 different languages. So I combined everything into one clear, short, English video that shows every step of the disassembly and reassembly process. This high-pressure fuel pump is commonly used on Opel / Vauxhall vehicles with the 2.2 petrol Z22YH engine, including Opel Vectra and Opel Signum models. If you need a clear, no-nonsense guide for rebuilding the Z22YH fuel pump itself, this video is for you. ⚠️ Always work carefully when handling high-pressure fuel system components.
