Hey I bought the RX7store's ultimate fuel kit for my rx7. I keep having a problem with the primary injector not wanting to seal and the car idles like crap and dies if you give it gas. The primary injectors are 1000cc and the rail is a KGparts rail. I was told that using a piece of 3/8th" heater hose would make it seal but it only worked for 2 hours before it failed. Then i tried a 88-91 S40SX lower injector seal because i local speed shop said it would work and still no luck. Someone please tell me what seal will work.
Thanks,
Phil

 

anyone?
