You have missed the safety steps:
Always have a fire extinguisher handy.
Disconnect the harness then start the car to remove fuel and fuel pressure from the lines. I also loosen the fuel cap.
Disconnect the battery.
Keep all heat sources well away and avoid static clothing.
You will also need to source all o-rings and pump seals within the filter/pump assembly. If you do not, then you will risk hard starting issues. Ignore at your own risk.
You will very soon see that it is far more fiddly and time consuming than you were expecting.
