Thank you all so much for the information.this truck has 80k original miles. I went ahead replaced the stock lift pump with a new made in USA precision replacement pump from Orielys Auto Parts for $152.00 .Other than the scrapes on my forearms....I completed the fuel filter change and replaced the lift pump in an afternoon. Again thanks for responding.This is my first diesel and just trying to learn all cautions and maintenance to avoid the VP 44 replacement issue. I did fill the fuel filter housing to aid in initial start after bumping the starter. It fired in 3 attempts and is back running
now. HR 20
