Hi tweeezzzy,

When you change 1, you don't need to change all, but it is preferable to do so or at least get those not changed serviced.

They are all plugged into the fuel rail so would all come off at the same time, only thing you can do is get them out sticking to the rails and not the cylinder head, then you won't affect the O rings.
