This is very long winded, but I figured it would save a bit on questions in the comments, plus I tend to ramble. 
I’m not sure if this is the right place for this or not, if it is not I will be happy to move it. 
 

In late 2018 I bought a 2002 3500 with an NV5600 more out of necessity than want(wrecked mine and had to leave for a job)
it had 160xxx on the clock. A few scratches   here and there nothing crazy. It drove decent typical 2nd gen problems that I knew of non existent dash top, ac was questionable , small but noticeable oil drip. The money was right 10k I bought it. Now
I’ve always been a Powerstroke guy not a Cummins fan. So I knew little and less and didn’t care at the time as I always have a company truck and never drive my personal but on the one day off a week I get. Only to a state and home when it’s over. Plus I was just gonna get rid of it when I got home to get my Powerstroke.
I started to try and get this thing a little more reliable to make it home as this job is finally winding down. I’m averagely mechanically inclined. I knew my Powerstroke inside and out. However I quickly realized that the 98.5-2002 Cummins was as a whole a completely different animal. 
I took it to a shop for some bucking and dying with white smoke and dead pedal. 
put a 44 and a fass signature series 100gph. Problem solved except for my water in fuel light came on which sparked the last month long dive into information and knowledge to fix this truck the right way and made me fall in love with this motor and truck. I want to see it running right and fixed so I can keep it.  I finally have had time to start going through this truck(only 60hrs a week instead of 90-100) the shop did a half assed job of installing the fass system. I’ll delve into that in the comments if anyone cares. The person before me half assed everything. List of parts added that I know of. Afe cold air, Banks Monster Intake horn gasket(manifold gasket leaks).smarty set on SW9 and Revo at 4-4-4 I’m assuming he thought that was max(since changed after reading pespi71oceans write up) and mangled together 4inch muffler delete welded to the 3in stock exhaust.

I started at Cumminsforumn.com reading countless articles, write ups, and basically anything I could find as to how these motors should be cared for fixed and upgraded(the right way) which led me to finding this site, and the amount it has helped in endless. 
I have finally started to order performance parts to replace failing parts as I have found them and me being a hp junkie and don’t want to replace with stock just to turn around and buy again.
I said all of the above to ask if you all have a shop or a vendor that you order your performance products from,if you have a list not just one or two things, that will work with you as far as giving you a decent price not just Msrp of each individual piece. I do plan to order all at once not just one thing here and a month or when “I get my taxes or have some extra income coming in”. I have money in hand and know that Performance and basically anything diesel related isn’t cheap. 
 

Any help would be appreciated. 
Thanks, The New Guy

Terrible spelling and grammar fixed to make a little easier reading

I will check.  Started going through emails and forums and started here on this site first.

250k miles on my first AD 150 pump after 13 years. Lots of idle time!

That's pretty good @Mopar1973Man.  I would be ecstatic if had an electric pump last that long.  Quite a few have gone through 2-3 electric pumps in that time span.  I personally had gone through 2 myself in a much shorter time period before I went mechanical.  If my mechanical pump doesn't last at least twice as long as yours did I'll be disappointed in it. 

Already got over 100k miles on my current pump. I'll most likely make 250k miles again.

That's very impressive for electric pumps.  I used to watch my fuel pressure gauge more than my speedometer when I was running electric.  I've only seen it once or twice since switching.  I'm gonna look to make sure it's still there next time I get into the truck.

I never even look at the fuel pressure gauge just watch for the light if pressure is low.

I don't think I have one of those...it's been so many years since I've thought about fuel pressure that I just can't remember.  Of course there's alot of things I can't remember these days...
