Float Fuel Switch 8M0007943 880596522 for Mercury Mariner EFI 4-Stroke Outboard
Product Overview
Float fuel switch sensor for Mercury and Mariner EFI four-stroke outboards, supplied as 1 x switch. It replaces Mercury 880596504, 880596522, 880596524, 8M0007943 and 8M6000359, and sits in the fuel system to signal fuel level or water-in-fuel condition to the engine management. A failed switch shows up as a fuel warning that stays on, a gauge that reads empty with a full tank, or a motor that drops into guardian mode for no obvious reason.
