Seachoice Fuel Sending Units: Reliable Monitoring on the Water
Knowing exactly how much fuel is left in your tank isn't a luxury on the water — it's a safety essential. Seachoice, a trusted name in marine accessories since 1988, brings that same commitment to reliability and value to its line of fuel sending units, giving boaters a straightforward, dependable solution for accurate tank-level monitoring.
Built for the Marine Environment
What sets Seachoice's fuel sending units apart is their purposeful, marine-grade construction. Non-ferrous materials throughout the unit ensure long-term resistance to the corrosion and moisture that rapidly degrade lesser components in saltwater and freshwater environments alike. These aren't automotive senders repurposed for the dock — they are designed from the ground up for boat fuel systems.
The swing arm float design is a standout feature: the arm can be rotated in 90-degree intervals, allowing installers to clear tank walls or internal baffles without having to modify the unit itself. This adaptability makes Seachoice senders a practical fit for a wide range of hull configurations and tank geometries.
Broad Compatibility Across Gauges and Tanks
Seachoice fuel sending units are engineered to work with both gasoline and diesel applications. Their electric senders are compatible with a wide range of gauge resistance values — from 35 to 240 ohms on swing-arm models, and 33 (full) to 240 (empty) ohm gauges on reed-switch models — covering the vast majority of OEM and aftermarket marine gauges found on production powerboats. Multiple stem lengths are available to match different tank depths, from compact 6-inch tanks to deeper installations over 27 inches, so finding the right fit for your vessel is straightforward.
Each kit comes complete with mounting hardware and a gasket, making these units a true drop-in replacement for aging or failed OEM senders. The standardized 5-hole mounting pattern aligns with the most common configurations found on popular boat brands, further simplifying the swap.
The Seachoice Standard
Seachoice has been delivering quality marine accessories and OEM replacement parts since 1988, growing its catalog to cover thousands of products across dozens of marine categories. The brand's sending units reflect its broader philosophy: manufactured to rigorous standards to ensure proper function, built by people who actually spend time on the water, and priced so that maintaining your boat doesn't become a financial ordeal. A one-year limited warranty backs each unit against manufacturing defects, adding extra peace of mind for the DIY boat owner.
Whether you're troubleshooting a fluctuating fuel gauge on a classic cruiser or doing a full instrument panel refresh on a center console, Seachoice's sending units deliver the accuracy and durability the marine environment demands.
