2008 - 2010 6.4L Powerstroke
The OEM requires that anytime 6.4 injection lines are removed or loosened,
they MUST be replaced. Fuel system pressure on the 6.4L maxes out at
nearly 25,000 PSI and even the tiniest leak will cause oil dilution and
possible engine damage due to the under-the-valve-cover location of the
fuel injector and line assembly. Don't risk catastrophic engine failure
by re-using old lines.
6.4 Powerstroke fuel lines replace the following part numbers (and others):
