Fuel Pressure Regulator - How Many O-Rings Should It Have?

[ATK 143 1 Cars]

Ordered a new FPR (Bosch) and it comes with one new o-ring as pictured. Should it have any more o-rings or can I just get on with swapping them over? Don't want to disturb anything until I know the part is complete.

 

Cheers

It only needs the O ring that is on it which is where it connects to the fuel rail.

There should be a plastic backing ring behind the o ring.
