the little round small green seal is for hte top seal and then all you need to do is drill out hte big green seal. the rest is well, no use.

 

2 manifold seals, rail seal, and rail cushion. don't use the black manifold seal (stock inj) use the green one.

 

couldn't i drill out the injector seals that came stock on my car?they are for stock 240cc honda non resisted injectors

 

yes you can drill out the stock seals too.

 

yes you could drill out your stock ones BUT... Think of this depending on the year of your motor the seal have been in there how long? They dry get brittle crack ect. if your going to do it do it right if you just want the green seal go to the dealer and buy them.

 

this injector seal kit. what car specifically was it for.
is this like a universal kit?

 

it's for civics. i wouldn't use the black manifold seal since it is shorter and will leave the dsm sitting too low in the rail and not getting as good of a spray pattern. using the green one will leave the pintile in the same position in the rail since the dsm inj is slightly longer on that end. you'll just need to dremel out the inside of the seal. be sure to replace the rail seal on top of the inj too since you have it...you don't want a old/bad seal causing a fuel leak and fire.
