I received the new 42lb injectors yesterday and got my tune that i will load through my computer. I am removing the fmu and installing the new injectors this weekend along with the pcmforless tune. I am going to use new motor oil on the O-rings to help install them. Is there anything i should do now that should also be done, cleaned or replaced?

 

i would do a fuel filter while you at it.

 

I replaced it about 500 miles ago.
