You should get new o-rings and bottom seals....leaking gas on a hot engine does not make a good combo...better safe than sorry

 

so i am missing something there? or?

anyone?

Ahhh...Siemen 76lbers??? Ypu need to take the O-ring and the fuel rail to the hardware store and test fit O-rings until you have the right one. I just used the O-rings from my stock injectors....make sure it is a very tight fit. I use a bit of oil to get it to fit into the rail. HTH

76lbs = almost 800cc

 

how can you tell the size by looking @ the injector?

 

Anybody know where i can find some RC 550 O-rings? Or will stock ones work fine?

 

stocko should be ok...may need some boring...otherwise go to http://www.rceng.com e-mail customer service...they're pretty good there...got mine in 5 days and I live in Japan

By the number on the side.....and another thing...you are going to need to have them machined to fit inside your rail. Either that or you will need to drill out the rail. Good luck
