Moeller Swingarm Electric Fuel Sending Unit Kit – 4" to 28" Tank Depth
A complete, ready-to-install electric fuel level system for boats with tanks ranging from 4" to 28" in depth. This kit includes a swingarm electric sending unit and a dash-mounted gauge — everything you need to add accurate, reliable fuel level monitoring to your boat without a conversion capsule or additional components.
Best Use Case
Use this kit when installing a new fuel level gauge system on a boat, or when replacing an existing mechanical sending unit with a modern electric system. The 4" to 28" tank depth range covers the majority of standard marine fuel tanks, making this a versatile choice for most inboard and outboard setups. The included dash-mounted gauge connects directly to the sending unit — no conversion capsule required, unlike mechanical systems. For a mechanical sending unit alternative, see the Moeller Swingarm Mechanical Sending Unit. For electric sending unit kits in different tank depth ranges, see the Seachoice Electric Sending Unit Kit (6–24"), Seachoice Electric Sending Unit Kit (6–27"), or Seachoice Electric Sending Unit Kit (6–12").

Parts Desk Insights
The two most important pre-sale checks are: (1) confirm the customer’s tank depth falls within the 4–28" range — if the tank is shallower or deeper, refer them to an alternative kit; and (2) confirm they want an electric system, not mechanical. Electric sending units connect directly to a compatible gauge without a conversion capsule; mechanical units require a capsule if connecting to an electric gauge. If the customer already has a gauge and only needs the sending unit, the Moeller Swingarm Mechanical Sending Unit may be a better fit. For a standalone fuel level gauge, see the Stewart Warner Deluxe Marine Fuel Level Gauge. For alternative complete kits in different depth ranges, see the Seachoice kits: 6–12", 6–24", and 6–27".
