I have a set of rebuilt injectors by Don at F1 diesel for sale. They are out of a 2005 with 55k miles on them. I sent them out to be tested and repaired. They have 6 new control valves (the part that wears out and give you high return rates) and new STOCK tips. These are not flux tips just new factory tips. Tested and ready to go. I can be reached best at davem3261@yahoo.com. $1450 +shipping
