Install of bypass valve trouble

[Sachelle Babbar <sbabbar@iris.nyit.edu>]

On my old 5kt (84), the bypass valve was very easy to install because I
had a 3rd outlet on the ic that was used. My new(er) 87 doesn't have the
third outlet. There is a circular raised area there, but I don't know if
it's a cap, or if I have to drill into it. If I drill, I think I'm going
to have to JB weld or epoxy the valve to the tank. If I go this route,
will jb or epoxy be strong enough? Which is better?

get through this thing together so I can go back to doing what I do best: 
killing you with beer."
