fuel pump sizes

[375instroke]

Is there a shorter stock fuel pump than the 472/500 fuel pump? I think I remember that the 425 has a shorter pump.

425 pump is same size. Outlet just in different direction.
For a shorter pump, buy a Holley 455 Olds pump. Switch your Cad pump arm into the Olds pump. Just press the pins out that mount the arms in the pumps, switch in the Cad arm.
Make sure you get the forked end of arm back in the pump in the right place.
