i'm installing these injectors on my H22A and the o-ring that seals the injector in the fuel rail always rip on me when i try to install them. the green o-rings that came with precision were much worse than the stock o-rings. i got one o-ring on w/o ripping it so it is the only one that is sealing well and not leaking fuel. when i installed them, i put oil on the outside of the o-ring to try to get it in w/o ripping but to no avail. my question(s) is/are: is it ok to use factory o-rings with these injectors? any tips or advice on getting the injector in the rail w/o them ripping other than use oil? thanks.

 

I use WD-40 , they will go in very nice with it

 

i just installed from precision injectors last night but i used the oem o-rings instead. what i did was use a little wd-40 then angle them in and use a small flat head screwdriver to help keep the o-ring from stretching.

 

silicone spray would be better
