Hi im new to the forum and have had my 05 2500 5.9 for about a year now. Its at about 101k. I was wondering if anyone had a fuel schematic and any info on the fuel system would be appreciated. Im thinking about installing some performance parts but I want to know what I got first. I have gone through alot of diesel training and could do all my upgrades myself.....I hope. I hope to add some input into this great forum, I diagnose problems daily on cat engines and cummins is quite similar just some minor differences from what i can see. Anyway thanks for the help.

 

Here is a quick text schematic of your system.
Fuel tank - intank lift pump - steel fuel lines - fuel filter - CP3 - common rail

If you are getting a aftermarket lift pump, the instruction supplied and the search function on this site will easily get you thought the install. There is even pictures/video of other installs on this site. It doesnt matter what brand you go with, they are all about the same.

 

Thanks sevir, So is CP3 a high pressure pump that creates all the pressure for injection or do the injectors intensify the pressure. Only curious because im wondering if there are any adjustments for height on these injectors when i do them, or any lash adjustments for a seperate rocker. I want to send the nozzles out for power upgrade and do it all myself.

 

NM I got it some research did the trick. Some great articles on these forums for all kinds of upgrades. Now to figure out which injectors im going to go with!
