i plan on sending in my direct injectors and fuel rails in (250 pro xs #2B088819) for service, cleaning, etc. and have a few questions. i had a compressor failure but caught it early, very small amount of metal in compressor crank, only trace amount on top of piston and none in filters leaving comp., but nonetheless i know there is a chance it made into the rails. i removed the complete rail including hoses and packaged direct injectors individually, numbered according to the cylinder removed from. i haven't printed off the form yet as i don't have a printer but will have the wife do that monday. (1) i know styrene is a no no but is the pollyethylene type foam ok? i tested with gas and oil and seems to have no effect. (2) what is approximate turn around time? (3) how much should i insure the package for? (4) is there anything else i should know/do before shipping? thanks.
