If your not familiar with doing this, it would be best to send the complete fuel rail in for service. http://brucatosvs.com/
Brucatos injector service is completed by one of Gary Brucatos techs at a completely different location now. July last year mine were sent to them, tested, cleaned, retested and sent back without any explanation, recommendation, etc... Sheet sent back basically said they were all OK. 10 hours into break-In of freshly rebuilt motor I burned #6 piston. Took off the injectors and computer and sent back to them. Guy calls me up and says the filter baskets are full of what looks like fine particles of rubber from deteriorating fuel lines caused by ethanol--this is the same stuff that was in them the first time he says!!!
That would have been a nice thing to know the "FIRST TIME"-----$150 worth of hoses cost me an additional $1500 on an already very expensive rebuild---I will never use them again!!! Many Go-Fast guys use someone in TN and say he is the best there is. I will try to find his contact info.
