Default injectors wont stop leaking

switched my old injectors which were 50lb racetronix to some 42lbers i picked up on ebay. i have an l76 intake and ls2 rails with Katechs spacer kit to use EV1 injectors. didnt have any problems with my 50s, now that i switched to the 42lbers multiple injetors were leaking real bad, so i changed the o rings on the railside, now just one is leaking like niagra falls and another is a slow leak. i dont know what to do now, any ideas?

if the 42's were fords they have smaller o rings by .5mm Why don't you use the o rings from the other injectors.

i sold my otherinjectors with the orings on them, i went and bought o rings for a car with an ls2 and they are still leaking.

ill take everything apart, **** with everything a little bit, because my spacers for the rails dont seem tall enough and the tabs will bend down where the bolts go through when i tighten the rail down so i tried to bend them back and use washers, but they are still leaking, they arent leaking as bad but they are still leaking pretty good. most of them were leaking before now its just 3 of them

the problem with using ls2 o rings is that the id is bigger than the ev1 Id.. so whats happening is the o ring is not sealing the stem of the injector. did it feal loose on the injector. You need the right injector seal. Leaks cause fires.The spacers you have are also 3/16" to lshort. so put a shim between the rail bracket and the mount so the rail sits properly. .PM me your address I will send you the correct o rings
