Good afternoon I just finished writing a 3 1/2 page article on the Cummins fuel system and lift pump. This valuable information is based on hundreds of tests and 14 months of work. This article is number one in a six part series. I thought this would be of interest to the forum. Feel free to post the link, publish it, or share with your diesel friends. I want to get this information into the hands of 4 x 4 users, diesel performance enthusiasts and truck owners.
