Rule 403FC 800 GPH Livewell Pump with Straight Seacock Inlet - 12V DC

The Rule 403FC is an 800 GPH livewell pump built to keep bait and catch healthy with efficient, consistent water circulation. Its straight seacock inlet design supports dependable operation in demanding marine environments, while advanced anti-airlock protection keeps water flowing consistently even in challenging plumbing runs. The pump's high-efficiency motor and impeller are designed to optimize bait health, and a secondary inlet port allows a washdown pump to be connected for added functionality without a separate through-hull.

Serviceability is built in: the Rule 403FC uses a one-hand twist and click motor cartridge system, so the motor cartridge can be removed and replaced quickly even in tight installation spaces, without pulling the whole pump. It is engineered to withstand the higher inlet pressure produced by high-speed water intake scoops, making it a good fit for modern fishing boats and high-performance vessels that need reliable livewell circulation at speed. The pump runs on 12V DC power with a 3/4 inch NPT threaded straight seacock inlet and a 3/4 inch hose barb discharge, and it is compatible with multiple installation configurations.
