Tunnel ram or no tunnel ram...

I discovered major vacuum leak today. I will report on this very soon.
It may be a source of my problems.
It behaves very bad and was not like that on my 1st drive. Perhaps silicone I used to glue it is not gasoline resistant. I will make a gasket for it today.
I feel like an *** quite frankly. I will report tomorrow. Will work on it tonight.
