Installing a 2nd hand Bosch CP1. Any tips?

[Uberderv]

+1 For not opening it. I would just fit with new cambelt etc...(if needed) as for tips, drain and remove the fuel filter housing for better access. If your belt etc is new you can swap it quickly by locking the engine, securing the belt on the cam pulley  at 9 and 2 o'clock with cable ties. With a friend to keep tension on the pump pully/belt you remove the old'un and fit new one straight away, bolt it back together, remove ties and locking pins etc.... job done.

While the filter housing is off I would open it up and give it a good clean out. Welcome to the club BTW
