This is the most advanced mechanical thing I've done, apart from a power steering pump on a van a few years ago.
It went very well, if not slowly, largely because I was terrified of dropping stuff in silly places! Plus huge learning curve.
Happy to say that the difference is immediate, feels like a different vehicle now all the fuel is going where its meant to

Bonus advantage in that I was granted permission to take it to work, so whilst it was 4°C, raining and windy, I was indoors with a big heater on! Onwards to the next thing to sort!
