I didn't even receive instructions w/ the F-Max kit
I drilled into the oil pan while still on the car. You tap it by hand so it's easy to take the shavings out. In addition, flush the oil once complete.
If you find oil fittings that don't fit, run to your local auto store to source them (1/8NPT vs 1/8BST). Also, the SS oil send line was too short to run beneath the engine so I used a basic steel brake line ($1) into the oil pressure sending T, down towards the oil pan, then connecting the SS line to the turbo.
Email me if you need more help.
