192 fuel injector grommets
 

My gasket kit gives me 6 plastic donuts - 4 narrow with a white dot, 2 thicker.
Do the primary and secondary injectors use different seals?
Parts manual page 1000A shows different numbers for the 2 injector sets but on page 1325A it shows 13-257 for both primary and secondary injectors, but labels primary No.1 and secondary No.2.

Can anybody clarify what the 2 parts in the picture are for? I don't want to have to strip down for a fuel leak once it's back in!

The parts on the left go on the primary injectors . Be careful to check there isn't one left in the hole they go into before fitting the injectors !
The parts on the right go on the seconday and p2 injectors on a 6 port or the secondary only on a 4 port . Be sure to lube the inside hole and the o ring on top of the injector before fitting the fuel rail !

Be super careful when fitting the rails that you don't misalign them and pinch the o rings or the grommets. This will become a huge issue for you if you get it wrong!

Thanks again! We'll see if I got it right when we get to start up!:blue:
