The first conduit may include a snout having a tube and a collar positioned at an end of the tube. The collar may include a flange extending outward from a center of the tube. The second conduit may have a main body and a saddle at an end of the main body. The saddle may include a track shaped to receive the flange of the collar of the first conduit. The saddle may also have a resiliently separable gateway comprising two opposing projections configured for receiving therebetween and partially enclosing the tube of the snout. ## Claims ### Claim 1 A conduit assembly for a gravity separation device, said separation device having a separation compartment defined in part by a sidewall, said conduit assembly comprising: a first conduit configured to be removably coupled to a second conduit, said second conduit being coupled to said sidewall, said first conduit comprising— a stem having a bottom segment defining an opening configured to provide fluid communication with said separation compartment; a snout comprising a substantially cylindrical duct spaced from said bottom segment and extending from said stem; a second conduit comprising— a main body defining a hollow passage configured for fluid communication through said sidewall with an exterior of the compartment, said main body comprising a first end fixed to said sidewall, and a second end characterized by a saddle configured for coupling with said first conduit; said saddle comprising a resiliently separable gateway including two opposing projections configured for receiving therebetween and partially enclosing the duct of said snout. ### Claim 2 (depends on 1) The conduit assembly of claim 1, wherein said second conduit is removably attached to the sidewall. ### Claim 3 (depends on 2) The conduit assembly of claim 2, wherein said second conduit is attached to the sidewall by a nut. ### Claim 4 (depends on 3) The conduit assembly of claim 3, wherein the nut is received along a receiver attached to the sidewall, said receiver having threading along an outer surface. ### Claim 5 (depends on 1) The conduit assembly of claim 1, wherein said second conduit is integral with said sidewall. ### Claim 6 (depends on 1) The conduit assembly of claim 1, wherein each of the two opposing projections forms an end of a substantially arcuate lip, the lip including a seating surface configured to receive a bottom of the duct. ### Claim 7 (depends on 1) The conduit assembly of claim 1, wherein said saddle further comprises a funnel and a track at least partly defining a recessed cavity, said funnel being configured to receive the snout and slidably transition the snout into the track and the recessed cavity. ### Claim 8 (depends on 7) The conduit assembly of claim 7, wherein said snout further comprises a collar spaced from said stem, said collar including a radially extending flange. ### Claim 9 (depends on 8) The conduit assembly of claim 8, wherein: the flange of the collar includes substantially parallel first and second straight edges on opposite sides of the duct, and the track is at least partly defined by a pair of arms of the saddle, said track and arms being configured for receiving and maintaining alignment with the first and second straight edges of the collar. ### Claim 10 (depends on 7) The conduit assembly of claim 7, wherein the funnel comprises an inclined rim of the saddle that is substantially continuous on three sides and defines an opening on a fourth side that is configured for receiving the duct. ### Claim 11 (depends on 8) The conduit assembly of claim 8, wherein the flange of the collar is configured to engage with the two opposing projections of the gateway to resist separation of the first conduit from the second conduit in an assembled configuration. ### Claim 12 (depends on 1) The conduit assembly of claim 1, the snout further comprising a lift lug configured for attachment to a lift rod. ### Claim 13 A conduit assembly for a gravity separation device, said separation device having a separation compartment defined in part by a sidewall, said conduit assembly comprising: a first conduit configured to be removably coupled to a second conduit, said second conduit being coupled to said sidewall, said first conduit comprising— a stem having a bottom segment defining an opening configured to provide fluid communication with said separation compartment; a snout including a duct spaced from said bottom segment and extending from said stem, said snout having a collar spaced from said stem; a second conduit comprising— a main body defining a hollow passage configured for fluid communication through said sidewall with an exterior of the compartment, said main body comprising a first end fixed to said sidewall, and a second end characterized by a saddle configured for coupling with said first conduit; said saddle comprising a funnel and a track, said track at least partly defining a recessed cavity, said funnel being configured to receive the collar and slidably transition the collar into the track and the recessed cavity. ### Claim 14 (depends on 13) The conduit assembly of claim 13, wherein said duct is substantially cylindrical, said saddle further comprising a resiliently separable gateway including two opposing projections configured for receiving therebetween and partially enclosing the duct. ### Claim 15 (depends on 14) The conduit assembly of claim 14, wherein each of the two opposing projections forms an end of a substantially arcuate lip, the lip including a seating surface configured to receive a bottom of the duct. ### Claim 16 (depends on 13) The conduit assembly of claim 13, wherein: the collar includes a radially extending flange having substantially parallel first and second straight edges on opposite sides of the duct, and the track is at least partly defined by a pair of arms of the saddle, said track and arms being configured for receiving and maintaining alignment with the first and second straight edges of the collar. ### Claim 17 (depends on 7) The conduit assembly of claim 7, wherein the funnel comprises an inclined rim of the saddle that is substantially continuous on three sides and defines an opening on a fourth side that is configured for receiving the duct. ### Claim 18 (depends on 14) The conduit assembly of claim 14, wherein the collar is configured to engage with the two opposing projections of the gateway to resist separation of the first conduit from the second conduit in an assembled configuration. ### Claim 19 A method of servicing a gravity separation device comprising: inserting a lift rod through an access port of the device; engaging a conduit seated in a separation compartment of the device with the lift rod; lifting the conduit from a snap-fit attachment to an adjacent conduit; and removing the conduit from the compartment via the access port using the lift rod. ### Claim 20 (depends on 19) The method of claim 19, wherein the conduit is engaged by attaching the lift rod to a lift lug of the conduit.
