injector instalation

[big monkey racing]

I have a 1990 240 w/ a ka24-e and have had to change out injectors and i seem to problems with the instalation. I got my o-rings from meyers and the o.d. is ok but the i.d. seems too big. I squirt a little brake clean on the o-rings and sometimes they slide in but most of the time they go in but pinch on side down and they leak really bad. any sugestions on ways to install them with-out leaking.

if the oring don't fit properly, buy them at nissanor a local autoparts store have a oring gasket set that comes in different sizes.
