I am going to use an external single line milodon on the new engine with the swinging pickup (block one of the lines). I am wanting to run some kind of filter between the pan and the pump and have noticed you can pick up a used Oberg filter pretty cheap. I was curious if the Oberg filter had to be mounted or can it simply dangle between the lines. I run my fuel regulator dangling and I have convinced myself it aerates the fuel less now.
