Abstract
A fuel detection film includes a cyclic olefin copolymer that is insoluble in acyclic saturated hydrocarbons. The fuel detection film has a porous structure that defines a plurality of pores. The plurality of pores are configured to allow flow of a lubrication oil through the fuel detection film via the plurality of pores. A housing is configured to couple to a pipe flowing the lubrication oil. The housing defines a slot. The slot is configured to hold the fuel detection film. The fuel detection film, while held by the slot of the housing that is coupled to the pipe as the lubrication oil flows in the pipe, is configured to at least partially dissolve in a presence of an aromatic hydrocarbon in the lubrication oil flowing through the fuel detection film.
