Will my Mariner 4HP pull fuel from an external tank?

[Howard Sterndrive]

Or is it gravity fed? It has the integral tank and I wanted to tee in a quick connect in to be able to use an external tank. Will it pull fuel up? Thanks.
It's a 1991 4HP (Yamarinerha?)

Most gravity fed units do not have a fuel pump.
