My 2024 Dually build thread

[Flyin6]

And built up the monster ram with all the stock stuff:

 

[Flyin6]

I installed it twice.

Once was simply not enough. After bolting it on, I noticed the number one fuel line was missing, hmm...

So I had to take it off and bolt it back on once more after first installing the Banks-supplied hard line. There would have been one heck of a fuel leak had I left that one off ;-)

 

[Units]

Then I wrestled the driver's boost tube into place.

I removed the fender liner to gain access, which made the job much easier, down a few degrees from impossible!

That red sure does spice up the engine bay.

 

[Flyin6]

There was a myriad of electrical connectors to reconnect, and I think maybe two were easy to get to!

Thank goodness the wheel well liner was off so I only had to stand on my head while twisting 90 degrees to be able to "feel" where the connectors met with their sockets on the back side of the Monster ram...

 

[Flyin6]

Then the EGR stuff was reconnected

 

[Flyin6]

And the rest of everything was reconnected

It took quite a bit of cranking to get the motor to fire up, but it immediately settled into a normal idle.

I left the foam cover off the buel rail/lines so I could chack for leaks and because of that I heard the mechanical music that is all Cummins.

Here it is in the final steps to being completed:

Yessir, sure does!

We are looking at five days of rain. I still have to install the Banks DPF-back 5" exhaust.

One thing about it: it has this gigantic tip that has to be 7"-8" in diameter.

Me no likey the big exhaust tip look, seems to visibly suggest, "Hey look, I'm stupid and lack self-confidence." -Just me.

I'd prefer the subtle approach, so I am going to find a way of extending the 5" pipe to a location that is tucked up and not all that visible. Subtlety is in itself a statement.

In other news, I am awaiting the arrival of the new Expedition One rear bumper. I managed to back my truck into one of those steel pipes that limit parking. Well, I discovered the limit of the Ram's bumper, and, well, exceeded it!

what did you use on the boots when you reconnected all the boost tubes? Just make sure they are really tight. You dont want a boost leak or a boot to pop off under load. Just retighten after a heat cycle.

Have a lot of experience with this...

No Breck hair spray, although I was tempted!

I finally settled on nothing, and doing so made it difficult to get those fresh boots to move into place. I measured and marked the metal tubes to ensure I had enough of the boot past the bulge to clamp. Getting the clamps to stay straight is always the most challenging part. I want to say I redid one of those connections more than six times. Each time I would get it torqued enough to stay in place, I'd take a gander at how it turned out. Mostly crooked! I was not satisfied and had to redo it.

As with all things boost tube, no matter what you do, those boots and clamps are still going to do whatever they want!

I just ordered seven new Venon Power Tera Hunter XT tires for the truck.

They look surprisingly similar to one of my all-time favs, the BFG All-Terrain.

After only 19,000 miles, the Toyos are wearing poorly in the front. I would have to replace those two 255-80R17 tires for nearly $600, or take this opportunity to go up to the 35" sizing I really want. The entire price for the new Venom tires was $1578 to my door! That's stupidly inexpensive.

My thinking here is that the front end of these heavy duallys tears up tires, ball joints, and my nerves with surprising regularity. I do not like swapping two worn front tires to the rear, but I prefer to purchase new tires for that busy front end. Therefore, pricing is essential, and these Venom tires come in at just $221 each, even without my military discount.

Further, after a comprehensive search, I can't find anyone going negative on these tires. They seem to be a hidden gem in the tire world

I have a Banks tailpipe to install, but I may be going a little further than just a tailpipe.

After seeing all that soot in the intake manifold, I am considering a full delete, since I will have to purchase the $6K ECM package just to remove the EGR. It may be time for the full-court press... thinking.

Having said that, I will be ordering a new FASS lift pump. I am looking at the 165GPH unit, but so far, I have not decided whether to install a sump in the 50-gallon tank or drop it to install one of those Fleece units that actually allows us to use all of our fuel!

 

[Wheelz]

I just did the 165G with the Fleece sure flow...it was an easy connect. The sure-flow was ready for the quick connects from the FASS. Plug and Play...and you dont have to drill the tank but you still have to drop it though.

I am also scrutinizing that setup.

By doing the sump, I do not have to drop the tank; just use/drain what's left of the 50 gallons. But that factory lift pump will have to be dealt with. Seems like whatever route I choose, there is going to be a bunch of work. I have run a sump before. It's good because you get to use all the fuel. The bad part is you now have a vulnerable, low-hanging part, and those fuel lines are exposed to a lot of weather and wear/tear.

The pump and Fleece pickup would be the least invasive...

The front tires wearing is quite likey from the crappy OEM alignment, have you tried thuren alignment specs?

Also, I wouldn’t bother with a FASS… more problems than solutions. The stock filtration can’t be beat (period) and the OEM flow rate is sufficient for a lot more power than stock. Adding a sump has its own set of issues, as does adding external filtration. Unless you end up making over 600 rwhp even considering an external filtered pump is just a waste of money.

I'll go with the Thuren specs after the tires are installed. Thanks for the advice

I have the local GMC folks do my alignments. They have a good deal of experience with duallys...

Well, the FASS advice is interesting. But what about the stock fuel basket and the 1/4th tank issue? My thinking from what I have researched is that the CP4 may benefit from a good supply of clean fuel. I concur that the factory filters do a good job. I do like the Fleece fuel pickup, so although my experience is with sumps, Fleece's design has merit.

You also know I risk ridicule here...A Chinook guy taking advice from a "gun" guy! ;-)

What about that spendy Fleece pickup with the two pumps? Not necessarily for the extra flow, but for the redundancy?

Your truck has a CP3 not a CP4.

You won’t get any cleaner fuel with a FASS than the OEM filtration, you really won’t be able to beat the filtration the truck came with.

The in-tank pumps are extremely reliable and have fewer failures than the aftermarket pumps, so as long as you don’t outflow the stock pump there isn’t any good reason for an external pump. The stock pumps are easily capable of 500+ rwhp.

No 1/4 tank issues with the stock pump or pickup.

The CP3 just needs flow and has an input rating of -5 to +15 psi in this application.

The Sureflo setup is just an interface for the external lift pump. There isnt an internal lift pump....it doesn't come with it it since its configured to just run off an external setup. Its just a basket and sender... You wont run into the 1/4 tank issues or priming. Originally I was going to use a Beans Diesel sump to eliminate the 1/4 tank issues (which i've read people are switch over to this sump). I didnt want to drill my tank and discovered the Sureflo. In my situation, I'm doing a 2G build, I needed to feed my 10mm stroker CP3 pump that's going to feed 70% over sticks. My demand for fuel is is much more...It just all depends where you're going with your truck, power-wise...since you said "deleted"..that itself is going to take you down the rabbit hole and turn into a money pit

 

[AH64ID]

I thought 1/4 tank issues were only a thing with draw straws.

Sumps also have limitations from fuel sloshing. I’m not sure I’d want one on anything but a track truck.

Wow, I thought I had that crappy CP4. I confess I haven't looked for three pump chambers vs just two...

That's all excellent advice, I think I'll take it for once, not that a gun bunny ever told me anything that I paid attention to...First time for everything!

So, you're at a party and there is a gun pilot in the crowd somewhere
How can you tell which one they are?
Just wait long enough, they'll tell you ;-)
