My 1987 deville has been missing the intake hose that brings fresh air into the air pump. the hose before the inline filter is the part i need but can't determine if anything else is missing as w
The A.I.R. (Air Injection Reaction) System was included on California-emission equipped vehicles. The system is designed to provide additional oxygen to continue the combustion process after the exhaust gases leave the combustion chamber. The system begins with the outside air inlet, which is a short, L-shaped open-ended rubber hose running from the lower front passenger fender well into the canister. The black plastic round canister is located in the front passenger-side engine compartment, adjacent to the EECS (Evaporative Emission Control System) canister, which looks similiar, but the EECS canister has electrical connectors on the top. While the charcoal canister of the EECS is a sealed unit, the A.I.R. canister has a twist-off lid to access the disposable filter. The inlet hose goes into the canister, air then passes through the charcoal filter, and travels into the outlet hose (also made of black rubber), which then connects directly to a metal tube coming up the front of the engine. Please contact me if you need a diagram or photos.
