Pulse air system Volvo 240/260 (B27F) (-1977)

The Pulsair system draws fresh secondary air into the exhaust flow to burn off unburned residue, and on the early V6 B27F the non-return valve is a common check point – if it leaks, hot exhaust gases are forced back and the hoses dry out and crack. This category gathers the parts that keep the system tight on the 240/260 up to and including 1977.
