Hey all, I'm in the process of an engine swap and I have a few fuel injection parts I need to replace and have been having a real hard time sourcing them, hoping to find some help here. Any how, the two parts are shown in the photos and sit at the base of the primary injectors. Any help finding these two parts for sale would be great, I have searched with no luck. This is for an s5 turbo engine. Injectors look to be stock 550's but im really not 100% sure on that.

 

all you need

 

Perfect, thanks.
