WAAAAaayyyy back when I first became aware of diesel engines, I started
asking questions from those experienced in diesel operation and
maintenance. The earliest tidbit of info I received was, that for
maximum life and freedom from failures, the absolutely BEST thing you
can do for a diesel engine, is KEEP THE FILTERS CLEAN!
In the past discussions related to added pusher pumps, and/or relocated
Lift Pumps, it has become evident that while these mods are very
helpful in better fuel flow and PSI, they also create a potential fuel
blockage issue if they lose power or otherwise fail.
