1. Most of it changes how you want to install it.
Best thing I can tell you is the pump is gravity primed. Keep that in mind when mounting it.
2. Pump should have come with instructions on how to wire. Typically add a relay which is triggered by the fuel pump relay. You'll keep the same routing but use a 1" shorter belt IIRC.
3. RTV or this unicorn bill talks about: Permatex 26B
When removing, spray down with carb cleaner and let it soak in. That'll break it down so you don't damage anything trying to get it apart. The carb cleaner applies to RTV, have never tried 26B.
4. Heater hose. That clear stuff isn't designed for coolant and the heat. Heater hose is. Be careful when routing so that it doesnt rub. If need be you can use wire loom to protect it.
