newbie fuel pump question

[bimaldo]

This is probably covered somehwere already but I could not find it.

I am in the middle of a 350 engine swap in my 72 C20 - like for like, mostly.
The old pump looks like this one:


I ordered a crate engine that came with a new feul pump included like the holley one below.

The question:
what do I do with the the old vent line ? The new pump does not have anything to connect to the line. Can I just cap the old line?
I need help.
