Subaru ff-1/1300/1400/1600/1800/Brat 1970-1984 Repair Guide

Vacuum Diagrams

Print

Following is a listing of vacuum diagrams for most of the engine and emissions package combinations covered by this guide. Because vacuum circuits will vary based on various engine and vehicle options, always refer first to the emissions label found in the engine compartment, if present. Should the label be missing, or should your vehicle be equipped with a different engine from original equipment, refer to the diagrams below for the same or a similar configuration.

If you wish to obtain a replacement emissions label, most manufacturers make the labels available for purchase. The labels can usually be ordered from a local dealer.
