Storage & logistics

Storing remanufactured 1.9 TDI 90 hp injectors requires a controlled environment to preserve their precision and prevent contamination. Keep them in their original packaging or anti-static bags, away from moisture and extreme temperatures, as humidity can corrode the internal components over time. For garages, designate a clean, dry shelf or cabinet specifically for diesel injectors, ensuring they’re not exposed to dust or direct sunlight. Label each batch with the OEM reference and remanufacturing date to track rotation and avoid stocking outdated units. When handling, use gloves to prevent skin oils from transferring to the injector’s sealing surfaces, which could compromise performance. Regularly audit your inventory to remove any units showing signs of damage or degradation, maintaining a supply of high-quality replacements for the 1.9 TDI 90 hp.
