That can in the pic is a vacuum reservoir, it is for the ac/heat system, you should have a vacuum tree with several nipples, one has A/C above it, a line goes across the firewall to a check valve with two more nipples, one to the can you see in the pic, the other through the firewall into the cabin. They should be black.
The vacuum line for the fuel pump regulator comes from the back of the intake to the regulator.
Please use some punctuation in your posts, one continuous sentence is hard to understand.

I'll have to get my book out later to see when I get back to the garage, those vac lines on my car are being redone on my car too, if you cap that nipple on the tree it will have no effect on how the car runs until I look at the book.

This diagram shows the route for the vac line to the heat/ac controls, it's pictured like you were sitting in the passenger seat so the bits in the engine compartment are backwards, basically a line from the vac tree, marked AC, to the check valve, two nipples on the side where one goes to the vac tank under the fender, that's the one that has the littl blue can between the lines, the other goes into the cabin through the firewall,
