New replacement injection lines for the 1993 - 2000 Chevy GMC 6.5L Turbo Diesel engines with the DS4 electronic injection pump. These have the 14mm x 1.5mm fittings and are tagged for easy identification. Please use the picture (above) to identify which injection line you need.
These lines will not fit on the early 6.2L or 6.5L engines with the mechanical DB2 injection pump. If you're unsure which series engine you have, then please call before ordering so we can make sure that you get the correct line.
