Fitting injectors. What else do I need?

[VeeDub Geezer 0]

I've got some new injectors to go on the Corrado but before I dive in head first, is there anything else I'll be needing?

 

The injectors I've bought are brand new Bosch (0 437 502 043) with two rubber seals each and what looks to be top hats already fitted.

wd40 and some thick guage wire(welding rod or something like) cause you end up with seals stuck in the injector holes,hard to get at.

And dont forget to depressurize the fuel system
