Not sure were you live but if you live in a cold climate you will want a system that can provide both coolant bases heat and Electrical heat.
Plant Drive offers this.
We have coolant based heat for the entire system and Electric heat for various components.
The Hotfox fuel pickup and Vormax filter both use coolant heat. We also offer flat plate heat exchangers. All of our kits come with a Vegtherm, which is an electrically heated fuel tube you install just before the fuel entered the engine on it's way to the high pressure pump or injector pump if other then a Ford PSD setup. We also offer an Overnighter that can keep you Fuel filter warm so the oil will flow through it.
With a coolant only system your switch over times significantly longer since you have to wait for the coolant to get warm and then it need to unthaw your filter and get everything else up to 160F before you can switch over.
We also have kits specifically designed for the 2nd gen 7.3 and the 6.0 PSD.
