    Cat 257B 2 down on power

    Thanks heymccall.. That's good advice. Anything not caught in the left/transfer pump could accumulate in the filter head. I have installed the inline filter in the line from the tank to the lift pump. Initially I was concerned that the lift pump would not have enough suction head to pull...
