Introduction

The diagram below covers most of the fuel and vacuum line routing for 16V normally-aspirated 944 models. Cars equipped with an active carbon tank for fuel tank venting will have additional vacuum line routing for that system — its routing is similar to the carbon tank lines shown in the 1985.5 N/A 944 fuel and vacuum line diagrams (FUEL-13). Heater control valve and ventilation vacuum routing is common to all 944 variants and is not shown here.
