A fuel cap assembly according to an example of the present disclosure includes a fuel cap and a pipe stub that extends from the fuel cap and defines a first internal passage. A sensor element and a fuel tube are adjacent to each other and both extend from the fuel cap through the first internal passage. A cylindrical coupler is composed of an elastomer and defines a second internal passage that extends between an inlet port and an outlet port. The inlet port has a first inner diameter and the pipe stub is receivable into the inlet port. The outlet port has a second inner diameter that differs from the first inner diameter.

Embodiments of methods and systems of transferring proppant for fracking to reduce risk of production and release of silica dust at a well site are provided. An embodiment of a method can include positioning a plurality of containers each having proppant for fracking contained therein onto a conveyor at a well site, downwardly discharging proppant from each respective container of the plurality of containers, funneling proppant from the one or more outlets of each of the plurality of containers through a plurality of conveyor hoppers, receiving proppant onto the conveyor belt, conveying proppant on the conveyor to a chute, and depositing the proppant into the chute for use in a blender or other location at the well site.
