WHERE IN THE FLUID CIRCUIT THE PUMP IS BUILT TO SIT - submerged in the reservoir, spliced into the line, bolted to the engine, dropped into a well, or standing beside the tank. BOSCH PUBLISHES IT AS A FIELD ON ITS OWN DATASHEET, `Housing version: inline` (DFP 300), and the aftermarket data layer publishes it under four more names on named parts: Delphi `Position(s): In-Tank` and `In Tank or External: In Tank` (FE0114), Airtex `Position: In Tank` (E7000) against `Position: In-Line` (E2000), Delphi and Denso `Internal Or External`. IT IS NOT `mounting` AND IT IS NOT `installation_type` [A11], and the test that separates them is whether the same product could be installed either way. It could not: Bosch says so in its own words on the FP 200-7 - `for the installation outside the fuel tank (installation in the tank is not proven)` - because an in-tank pump is sealed, cooled and primed by the fluid it stands in and an in-line pump has screwed connectors, a self-priming suction stroke and a housing that must survive dry. `mounting` (freestanding, hanging, wall-mounted, railing-mounted, pedestal) is how a PLANTER is supported and `installation_type` (freestanding, built-in, countertop, integrated) is how an APPLIANCE fits a kitchen; both name a fixing, and this names a place in a circuit that the pump is designed around. One honest note recorded rather than hidden: the live `FilterForms` already carries `in_tank` and `inline` beside `spin_on`, `panel` and `cartridge`, which mixes a siting with a body shape in one filter vocabulary - a pre-existing observation on b153, filed as an obligation and not repaired here.
