2001 f350 wrong injectors?
 

I got a set of injectors for my mothers 2001 f350 7.3. Her garage told her that there is one different injector and that the set we got was not right.

From reading the #8 injector is a Long Lead. Does everyone stick with this setup or do you just do all AD injectors.

You can do either. The LL is still 140cc, just has a longer first injection shot.
