New owner of KW T660 ISX15 CM2250

[Longshot]

I wanted to thank everyone for the comments and I read the posts recommended by Rawse plus his book - a great learning experience and eye opener for sure.
I got pretty paranoid about the fuel pump and I checked my engine number on Cummins and found I have a 2012 CM2250 and the new 2 cylinder pump, but expect it needs the updated plungers and whatnot. I figured I would have it done at Mr Haggs but now wonder if I shouldn't just buy the parts and get them put in myself before sending the truck out on the road again.

Anyone know of any good videos on installing the updated parts? Or is that something I should wait and have Mr Haggs do? I'm pretty handy with engine work but mostly car stuff not heavy duty diesel.

Any help appreciated!
