vacum sensor
Have this sensor that was mounted on my ls1 near the fuel rail flex line.
It is not hooked up and I needed to remove it to put an engine cover on.
It never had electric, so that part is easy.
As for the vacum line, I have it disconnected. The engine runs fine, I do feel slight vacum on it when engine running. Do I need to cap it off or can I leave it as is?
where line runs to
and roughly where it sat before it was removed.
thanks for any input.
