Look at the fuel pump; if it has a return, 3 port / no return, 2 port. You can always get a 3 port just in case, and cap the return port if unnecessary.

I agree with fleming442, I suggest to get the 3 port even if you do not have a return, You can cap it off and if you ever change you fuel system and you need a return you won't have to change the sending unit again.
