Rule iL500 Plus Inline Pump Kit - 12V

The Rule iL500 Plus Inline Pump Kit is a 12-volt marine transfer pump engineered for serious boaters who demand reliable, spill-free fluid handling. With a flow rate up to 7 US gallons per minute and pressure output of 14 psi, this compact inline pump handles diesel, fresh water, and salt water with equal dependability—making it the workhorse choice for fuel transfer, deck showers, and washdown operations across commercial and recreational marine applications.

Rated for continuous operation, the iL500 Plus delivers consistent pressure without the surge and spillage typical of manual or gravity-fed systems. The 12-volt design integrates seamlessly with standard marine electrical systems via the included 4-meter battery cable with clips, eliminating the need for custom wiring. Salt-water compatibility is critical for coastal and offshore use; this pump's design resists corrosion in harsh marine environments. The kit arrives complete with a spray nozzle for precise application control, 4-meter layflat hose for deck storage flexibility, and all connectors needed for immediate deployment. A key operational note: while rated for continuous duty, extended dry-run cycles can damage internal impellers, so fuel or water supply should be maintained during use.

This pump suits weekend anglers managing bilge discharge and deck maintenance as readily as commercial fishing operations requiring fast diesel replenishment. The 7 GPM throughput moves material quickly enough to reduce downtime at the fuel dock or between offshore runs, while the 14 psi rating handles typical deck wash and freshwater shower applications without pressure-related leaks. Boaters operating in salt-water environments particularly benefit from Rule's proven corrosion-resistant materials, a consideration that extends service life and reduces maintenance costs over seasons of heavy use.
