vacuum check valve same as air inject chk valve?
 

My air inject chk valve was disconnected & hose broken
I cut hose & reconnected

Not sure what it does but guess its not a extra part if mb out it inthere

Is it the same as a vacuum check valve?

Part is $10 & mine is small green plastic cylinder attached to a quad vacumn hose at one end & other goes on a port on intake manifold

thought it might be worth to put in a new one?
That is if its the same part...

Vacuum check valve: (VCK-V) a one-way valve used to retain a vacuum signal in a line after the vacuum source is gone
Would be nice to know what it does
or rather if its not working what it does...

oooh this is interesting
think I see his green valkve but its in the back & connected by a y hose???
