You could have undone the securing clip on the breather hose. That would have allowed you to hold the pice in your hand , drill it and dry fit the pipe. I only know this as I've just done mine. Your several steps ahead of me as I've still to attach the fuel line to it. I need to find a nice place to mount my pump. Iam currently making a box to house it to try and muffle the ticking sound.

Hi, did you need to epoxy the sender unit after install ? We did the same as you not using any but just checking if you had any leaks later on ? Thanks, Lee

Hi, can you tell me where you got your fuel pick up pipe, mine looks nothing like yours and yours is much easier to fit, thanks heaps from Australia
