  "limits": "No direct owner dimensions or fitted ELC identities, routing, port assignments or operation are established. Factory PDF90 distinguishes ARH302/BHH1626 separator, one wing-valance fixing, early pipe/hose branches throughGAN6-182000 and later hoses/floor ferrule. No branch is selected as fitted. Separator polygon,24mm depth,1.2mm gauge, integral-lug contour, port sizes, chosen Y/Z and quarter-relative4mm standoff are construction estimates. A common quarter reference supplies a proposed mounting plane only; no body receiver hole, captive fitting, hidden reinforcement, support strength or measured seating is inferred. One smooth screw/washer/nut role follows the factory quantity, not fitted hardware dimensions. Tank-side taper follows the retained unregistered20.32mm neck and an8mm separator port with0.6mm radial display allowances; it is not a fitted reducer, material specification, stretch, hose/pipe variant selection or sealed joint. The product tank photo places a small port near the filler; retained tank port coordinates/size are explicitly not an RO9F reproduction and remain unregistered. The existing138.129544mm^3 tank-neck/floor source conflict is not erased. The new separator replaces the old floating brick and buried hose endpoints with a thin hollow outline and explicit wing-side mounting role, not a surveyed installation. No internal baffles, liquid/vapor behavior, complete pickup/feed circuit, purge plumbing or electrical function is modeled. The long8mm OD/6mm bore pipe uses estimated12mm bends and retained lower/front route and floor-opening axis; its endpoint remains open to the independently unregistered front-canister hose. Grommet groove follows the estimated1.2mm floor sheet without rubber compression or fitted diameter. New routes may intersect other source obstacles; no hot clearance, loaded body/suspension movement or verified service/removal path is established. Separation is illustrative.",
