What are these

Postby 42south » Sun Dec 20, 2020 7:18 pm

Hi guys
I’m looking to identify these bits. Also the vacuum connections off my 1991 Nissan safari alternator driven vacuum pump. I have one for the brakes and clutch, the small pipe for AC rev increase, and there is one other off take which appears to go around the front of the engine but is blanked off.
The bit I’m trying to identify in the picture is attached to the guard and has the 3 things using some form of vacuum

Thanks for the reply.
These are vacuum operated solenoid valves that operate the exhaust gas Re circulation system, EGR.
I have since noticed that the vacuum supply to them has been disconnected. So unknown to me the EGR has been disconnected for over 10 years.
The truck runs well with no smoke, so I’ll just leave things as they are.
