  "limits": "Factory/replacement exterior comparison, not fitted 13H8511 identification. Factory PDF91 / MD0020B lists 13H8511 and BHH102 for GAN6-154101 onward. Its illustration shows three upper necks and a lower end boundary. AHA9333 separate support bracket is explicitly finished at GAN5-154100; the retained mount blocks do not establish a GAN6 counterpart. AHH9658 strap is separately listed without that bracket change-point scope. Engel product201445 lists three outlets and 1974\u201379 North American Midget1500 application; its photograph is a separate replacement-family comparison, not a dimensioned or exact 13H8511 reproduction. The held canister center, cylindrical envelope, three port axes/tips, strap ring and two mount blocks come from the prior browser drawing. New 2mm casing/end sections and 6mm port bores are estimates. The former solid lid becomes a hollow cap with open bores; the bottom end is an inspection boundary, not verified detachable hardware or a reconstructed vent/filter assembly. Opposite-end projection and ribs visible in the replacement photograph are not transferred to the held factory-top-port drawing without a common orientation map. Charcoal, filter pads, baffles and internal pipes are omitted; the empty display cavity does not describe fitted contents or prove an operating vapor path. The first port retains the named tank-vapor comparison boundary only; other ports have no assigned purge/overflow circuit. No hose, body, cooling, heater, battery, engine or rear ELC part moves. Annular strap and mount blocks remain independent unregistered estimates; their contacts/gaps do not establish attachment, clamping or loaded support. No fitted circuit, emissions performance, material compatibility, seal, thread, safe removal or replacement procedure follows."
