Yes the one that is mounted is the somewhat working one. The one with the red powder coated canister is the one off of the pole car and looked to be brand new.
Now that you said dual mount maybe I am a bit slow.. That pump will fit as far as bolt placement but I noticed a area of the block showing that if I invert the pump (canister down) it will go in place however the fittings hit the frame that is right there. Unfortunately the pump does not have the removable lower section or I could rotate that part. But it would still be upside down?
Does this confuse you as much as me?? Car did make it all the way to work today without dying? We will see what is does on the way home tonight.
