Patent ID: 8601867

Claim:
A phase separation float assembly for use with a fuel level probe having a shaft extending into a fuel storage tank, said phase separation float assembly comprising: a first float subassembly comprising a first float adapted for vertical travel along said fuel level probe shaft and a first magnet, said first float having a first density; a second float subassembly comprising a second float adapted for vertical travel along said fuel level probe shaft and at least one stop feature which engages said first float subassembly when said first float subassembly travels vertically a predetermined distance along said fuel level probe shaft; said second float having a second density greater than said first density; wherein said first and second densities are selected such that: in the presence of either higher density phase separation or water, both of said first and second float subassemblies travel vertically along said shaft; and in the presence of either a higher density fuel or lower density phase separation, only said first float subassembly travels vertically along said shaft.
