Ford Bronco Secondary Air Injection System Diagram - Smog Pump Parts & Layout

This document is a Ford factory-style exploded parts diagram (figure reference A20801-A) of the Secondary Air Injection system, uploaded to the gallery of a 1995 Ford Bronco. The line drawing shows the routing of the air injection system on a V-configuration engine, with ten numbered callouts identifying components. Two legend tables list each item number with its Ford base part number and description: the downstream secondary air injection check valve (9A487), secondary air injection diverter valve (9F491) with its vacuum control connector, secondary air injection bypass valve (9B289) with its vacuum control connector and silencer ports, the secondary air injection pump (9A486), the upstream secondary air injection check valve (9A487), the exhaust manifolds (9430), and the three-way catalytic converters (5E212). From this document a reader can learn the names and Ford base part numbers of all major smog-pump/air-injection components, how the diverter and bypass valves connect between the air pump and the check valves, and where the air lines feed into the exhaust manifolds and catalytic converters. The document itself contains no year, model, or engine designation beyond the figure number.
