I just popped an O-ring coming back from a track day and a good amount of fuel is leaking from one injector. Anyone have an idea if I need special O-rings? I installed these about 6 years ago and really have no idea if I used the stock O-rings or not. Hopefully someone using Seimens Deka PN# 9266 310cc can tell me so I don't buy the wrong part.

Thanks!

 

yea i had a set of 580cc seimen deka they came with a huge o-ring so i bought 4 new ones and used a set of old oem o rings to fit in the space..so you use 2 per injector...but i ran it like tha never had a problem...make sure you use a lil oil around the orings so they slide in easy and dont break..

 

Any other input? I rather run one ring that fits.
