I think you mean Murphy's Law, (anything that can go wrong...will). Normally... I would agree with you, that getting everything out of the way is best. However... those PS hose seals can be very problematic, so I personally would prefer not to disturb them. They are too easy to roll, twist, tear... and generally fark up. It might be best to use tie wire or coat hangers to suspend the pump up and out of the way. Then compare the bolt holes to the diagram above and focus on getting the bracket mounted. If you have to... remove the airbox completely... and drain and pull the PS reservoir first.
