I have a set of RC 550 injectors with the pigtails for the 14's. They have been used to make four dyno pulls to test primary fuel consumption/hp only. Have a modified stock 14 fuel rail also. It has a 6an return connection welded. The rail was on a 07 14 but will fit all. Has all necessary hardware and a flow sheet with the spec's. 400.00 get's it.............Bill
