When I was changing my throttle body boots on my sled I took the top injectors loose. Well I am not sure if i got them all the way back in. So I was wondering if anyone could tell me how far they need to go in. Like does the black plastic of the injector need be tight to the injector hole. I can see what appears to be an aluminium sleeve in front of it and I can't seem to get that to go in all the way. The sled is 2008 700 RMK.
