Haha good call mate!!
And yeah I get now what your both saying, it all makes sense once you stop and think about it.
Adjusting the fuel pump timing did drastically reduce the tapping noise however it is still more pronounced then it used to be so will have to look into that.
Overall though it is running smoothly and I couldn't be happier! Just have to fix the wipers so they stop blowing the fuse all the time and my Defender will be up to scratch again:)
