MEP-006A help identify modification

[Suprman]

I have a MEP-006A it has an odd setup installed. There are extra oil lines and coolant lines, there is some type of agitator or pump mounted on the oil pan and there is some housing on the gen with an opening on the front right. Anyone know anything about this?

If you are talking about the thing with the red hoses connected to it, it appears to be some type of block heater.

The tube part may be some type of filter housing. There is no heater part to it. The bottom of the first pic is a small electric motor going into the oil pan.

Is there some filter that goes in the tube? There must be a coil or something in the oil pan.

The tube is where you insert the swingfire heater. All part of the arctic kit.
