Recently my #1 injector started leaking from the upper o-ring. Upon removal the o-ring is warped and will need to be replaced. Does anyone happen to know the size of the Bosch EV14 640cc injector's upper O-ring? This is on a long nose 1.6L. I was told it was 11mmx1.2mm but I cant seem to find that size anywhere. Looked through Viton's catalog and can't find it. Thanks !
