Newbie to the scene, I'm really enjoying all the threads and the info is great.

What mods, or aftermarket upgrades are available to replace the lift pumps on the 03 HO cummins?

Since they are assumed to be the "weak link", has anyone replaced, or added a electric pusher pump etc. to help the lift pump out?

Also, has anyone used the Bully Dog dual exit 4 inch exhuast? If so whats your thoughts of these systems.

I haven't done a thing to my truck yet...But man this site has given me some great ideas though... thanks again to all

Thanks for any replies.

I have a stock 2005CTD and the mechanic told me that a lot of pumps go out because of algae buildup in the tank. He said to run an algaecide every three months.
