Notes on arrival: you may notice a light fuel-like scent from the new unit. This comes from protective oil used during production and shipping and is not an indication of a used product. If the unit arrives damaged or fails to function as expected, reach out for assistance. Slother is committed to delivering value through reliable parts and responsive support.

Care and installation tips

Before installation, ensure the electrical connections match your 12V system, and check the mounting points for alignment with the engine or machine. Keep fuel lines clean and free of debris to help maximize the pump’s effectiveness over time. A careful, torque-controlled installation can support long-term performance and ease of future maintenance.
