🔧 Product Description

Genuine Quicksilver Fuel Supply Module Float - Part Number: 8M6000359

A genuine Quicksilver fuel-level float for selected Mercury four-stroke fuel supply modules.

The float moves with the fuel level inside the module and operates the associated valve or level-control mechanism. Correct float operation maintains the intended fuel level around the electric fuel pumps and helps prevent flooding or fuel starvation.
