Does anybody have the part number for the green oem o-rings for the top of the fuel injectors. I have way better luck with using those on aftermarket injectors and getting them in the rail. The black ones seem to be a little fatter and won't go in very easily. Or are there any tips on using the black ones. Injectors i've been using are 'precision'. Thanks in advance.

 

any brake clean that evaporates quickly or 2+2 will do the trick. spray the o-ring, and it is like butter till it dries then it is tight as hell. try that. thats how i do all my installs.

 

thanks...i'll give that a shot

 

i just use a dab of oil.
