Injector rebuild?

[05chevy]

Hey guys got a buddy that has rcd 190's and they are starting to act up pretty bad. Missing and popping. He was wondering if anyone will rebuild the injectors. Or best to send them back to rcd? Thanks

Well either they worked loose and burned up orings or ran them out of fuel and scored the plungers are the two most likely problems. if its just orings he can fix um but if its internals rcd is the best bet since they have the exact parts in stock to fix um
