Hot Rods Fuel pump help

So I'm not getting fuel and took apart my mechanical fuel pump. The motor is an early c1500 454, '73 or'74. Checked the rod length, good. Then I looked at the pump and noticed the arm looks a little short and it has 2 ports on it, I thought the 454 had 3? Looks like maybe a small block pump.

My question is if I get the correct pump with 3 ports, I don't have anywhere to put the return line on my '30 roadster with moon style tank.

Is there a certain year 454 that has 2 ports on the mechanical fuel pump? Do I cap the return line?

Thanks.

 

get a 2 port pump. There are several pumps available for the big block.
