Was there any kind of follow up with this.

Check your pms I also emailed your website.

I don’t have either of those. My fass runs straight to the injection pump. The shop took all of my stock stuff out and not the right way either. The sending unit is still in the top of the tank. However the put a sump in and ripped out the block mounted lift pump and filter housing. I had to plug the lines and plug off the factory wiring harness. Essentially my fass is my lift and sending unit, but I get what your saying I will use that fass as the “factory” system

So essentially I just need to see if the fass will free flow when not powered on? Which it should being that gdp gives you the option of leaving your fass ddrp in place and functional(shouldn’t be a difference in base design). Run the “to engine” line from the fass to the GDP pump. Then the return from GDP pump to the return on my tank. Throw a plug in the return port of the fass leave it wired up kicks on runs for a few seconds Hobbs switch kicks it off, or just leave the fuse out in the junction box in cab throw in if I need to prime the system.

So I’m guessing probably not? I could see if the fass could free flow when off where it would work unless the filters were clogged. Does the check valve keep fuel pressure from bleeding off (returning to tank)? I’m sure all of this isn’t worth the amount of effort I’m putting into figuring it out lol but now it has peaked my interest.

I guess it’s a more of a piece of mind thing with the filters so I suppose I will decide when I make the purchase. However the the shop that put the fass in took all of my factory lines filters and lift off the block back to the tank. Only thing they didn’t do was plug off the factory wiring harness so water didn’t get into it. Called them oh we threw that away yeah sure you did you got it on a shelf gonna sell it to someone needing it.

Well I was mainly thinking of the added filtration, and it’s already there. I get free fuel for my personal truck but they don’t always buy the best ?. I know I know just spend the money on diesel at a station, but I have a big enough transfer tank that I can usually make it 16-1700 miles without touching a fuel station. So that’s an added bonus on the lay off and going home usually saves you 4-500 dollars. However I like the water separator of the fass and the filtration it provides. I guess I could buy a housing and make my own but it’s already there ?

So this might be a stupid question. Can I leave my fass and sump installed(forgot to add to my signature) and just run the mechanical with the fuse pulled from the run start plug in the junction box? In my head it will work as long as the fass will free flow.

Lol I hear yuh there this one actually lets me spend most of what I want where I want so I can’t complain she’s just a tight ***??. Thank you for the advice I will for sure keep that in mind for the future. I really like the idea of a mechanical pump. Is it a pain to install? I need to do a little more research into because I don’t know much about them. I’m digging the shorty conversion. I got a buddy who is in the process of making a shorty out of a 2019 F450 single cab I’m curious to see how it turns out.

Thank you for that I see what you mean...I still have a lot left to figure out lol? I do plan to do this in two stages mainly so the wife won’t harass me to bad lol. So maybe I will leave the inside be for now Unless I should do both? I don’t really push it that hard unless I’m on the interstate and trying to maintain a constant 75-80 and I just cringe to see the tach setting so high for hours on end. This is a little off subject but has anyone swapped gearing with a thin carrier front and back?

I appreciate all of the advice guys. I will definitely be using them I do plan on getting with them for a final order and pulling the trigger on Monday when they open back up.

Yes sir that is for sure on the list.

I guess for this truck it is. If you think in terms of newer diesels your not even changing the turbo to hit 500 Shoot you don’t even have to remove the emissions.

I’m glad I’m not the only one who thinks that. I’m not looking for big hp out of this truck. More or less a reliable 550-600 and when I say reliable at any given time jump in it hook to a camper and drive across the country and not have to worry about it. That was more less something that I was doing because I was in there,but I wasn’t gonna do a cam or rods. I do plan on doing a compound set up in the future more or less for the better band of power while towing.

Thank you all very much for the input. Here is what I had in mind much of what diesel auto power has said. Quadzilla IQUAD 6x.011 SAC 150* spray sticks 62/68/12 turbo 103lb Hamilton springs (since I’m already gonna be in there and I need to adjust the backlash) arp studs On the fence about upgrading the lift pump. 1:I just bought it 2: there are so many conflicted opinions I have already bought a new exhaust and new gaskets for the grid heater and intake manifold.

Thank you! I have made my own list and looked over websites, but I finally had to ask I know it’s a question that most people on these forums hate. In my defense this is my first article and I have been reading here and cumminsforumn for quite awhile. So as to not ask a bunch of stupid questions that I could use the search bar for. It feels also there doesn’t seem (with the technology changes) there are much updated or new vendor referral or build advice, Not so much here but the other sites. I just want to compare the vendors I have found with the people in this forum. Even take advice to tell me not to order these parts ,or I’m an idiot if that is what is necessary. I don’t even care if it’s your personal favorite shop as long as they ship lol.

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
