1987 Jaguar XJ6 Fuel Vapor Vent Tubes in C-Pillars - Tank, Filler & Canister

This is a hand-drawn ballpoint pen sketch (not a printed factory document) depicting fuel vapor tubes routed through the C-pillars of a vehicle, uploaded to a 1987 Jaguar XJ6 gallery as "XJ6 fuel vent line." The drawing shows what appears to be a pillar or body section at the upper left with three tubes emerging from it and running toward the lower right. The three tube ends are labeled with their destinations: "canister" (the uppermost tube), "tank" (the middle tube), and "filler" (the lowest tube, which shows a short branch fitting near its end). The caption at the lower left reads "Vapor Tubes in C-pillars." A reader can learn the general arrangement of the evaporative emissions vent plumbing: three separate vapor lines pass through the C-pillar area, connecting the fuel tank, the fuel filler, and the charcoal canister. The sketch contains no part numbers, dimensions, torque values, year/model statements, or other technical data — it is purely an illustrative routing diagram intended to accompany related evap-system documents in the same album (Evap system.jpg; Jag fueling control.GIF).
