When the replacement fitting arrived did you happen to measure it?

The new fitting I received measures exactly 0.499" which is the same size as on my stock sending unit.
I'm thinking of replacing this with with a push-fit barbed fitting so i can run a hose directly off it to my LP/Filtration setup. Just need to figure out the size. I'm mic'ing the OD of the threaded part of fitting @ 0.563". Everything I read online states 1/4" nominal is 0.54" OD and 3/8" nominal is 0.675" OD. Not sure if this is a standard size or a special size or if i'm mic'ing wrong.

I did the tank install over the weekend. The install video states that you can do this job without using a lift but I don't recommend it. Even getting the tallest stands I have to raise the truck I still had to roll the tank on it's side and angle it a bit just to get it under the truck. This tank is huge. I'll take my hat off to S&B, they did their work on making sure this fits. I had some concerns with the retractable gooseneck ball mounted in the bed but there was about a half inch to spare. The main feed connection on the sending unit I got measured .506 (stock is .499 like @knotReally states) and I called S&B and they overnighted me a replacement and I was glad they did because the one on the sending unit was too tight, I was not going to force it. Waited till that replacement one showed up and it measured .499 so I used it and fit perfectly. One thing, make sure and tighten each of the fitting on top of the sending unit! Each of mine were not tight, not something you want to find out when topping off the tank or loosing the prime for your lift pump. Also when installing the sending unit I waited to install the float arm till the sending unit was partially in the tank. The fuel level sensor assy is pretty flimsy and I did not want to put any extra strain on it when installing. Fairly straight forward but installing the filler neck hose and clamp sucked. Not a big deal if you want to lift the bed but without doing that it is all by feel on top of the truck frame and very not much room to get into there with a 1/4 ratchet and 5/16th socket to tighten up the clamp. Everything works great. Looking forward to using it on my Colorado trip next week. Dean

Just got back from my trip to CO. If you are on the fence about putting this fuel tank on your Duramax all I can say is do it! I can't believe I waited as long as I did. Pulling my enclosed trailer at 75 mph I was stopping for diesel every 200 to 225 miles and paying crazy prices at the truck stops. Went from eastern NE to the central part of CO and still had over a 1/4 tank to spare. Fuel on the interstate was as high as $3.76 a gallon. I am able to wait and fill up in Omaha for $2.99 and in Fort Collins at $3.22. Not worrying about were to get my next tank of diesel is a big relief especially taking some back roads to more remote areas. I really like the baffles they put on this tank along with the small sump area for the sending unit. No 1/4 tank issues although this was not a problem on my old 26 gallon tank either. The sending unit seems pretty accurate. Mine old sender would show empty with the DIC showing only 19 gallons used. There is a place to put the lift pump return fuel at the bottom of the sending unit sump but I left mine as is. The FASS install has the return fuel going into the filler neck hose which dumps into the top of the tank right above the sending unit. The only thing I might add is an optional heater for the FASS pump. With so much fuel on hand it will take more to warm the fuel up in the really cold days of winter. Very happy with how things worked out. Dean

I installed the 62 gallon S&B last week. I opted to pull my bed to make things easier for designing and installing duel Kennedy lift pumps. I have a two post lift but with a six inch lift on the rig, motorcycle jack and a Hyster fork lift the installation was smooth.
Like mentioned, S&B hit a home run with this design. The clearances are perfect and even throughout. The fit and finish outstanding. Their customer service is equally impressive. My order was only delayed for around ten days but I was waiting on other fuel related parts anyway.

Out with the anemic OEM tank and in with the larger S&B.

The six inch lift allowed plenty of room to slide in the new tank without jacking up the rig. I did however have to slide the tank in first, then sneak in the jack.

Installed without drama. The inboard mystery bracket found on 04 and newer made for a good platform for mounting those duel Kennedy pumps.

The fuel cooler had plenty of even clearances and the scoop design promotes airflow.

A closer look at the fuel cooler opening.

The duel lift pump mounted to a custom bracket also promoted airflow to the billet pump housings.

The .120" 5053 aluminum provides as a heat shield and debris protection.

The mystery bracket got four 5/16-18 capture nuts welded in to facilitate ease of installation.

Pumps installed along with the shield.

Looking from the rear forward. The provided stud on the mystery bracket was also utilized for securing the fuel supply hose. The 4" exhaust muffler doesn't get as hot as one might think, prolly due to the free flowing exhaust from the turbo back.

The remaining instal was focused on the new Kennedy pumps wiring harness. A oil pressure switch was also added (oil filter housing) to complete a 12vdc circuit with the engine running. Also included with the harness is an override push button relay that allows power to the pumps without the engine running for priming filter changes. I have ran two filters since the rig was new. A Kennedy fuel restriction gauge was used prior to adding the lift pumps with a baseline reading of 5.5" of vacuum. With the dual lift pumps I now have a solid 6 psi to the CP3.

Anyone on the fence on adding an S&B 62 gallon fuel tank to a 01-10 CCSB, rest assured it fits like a glove.

Thanks BoiseRob, I wanted to add my first hand experience with the fit and finish of the S&B.
I also ordered mine direct from S&B and they reached out a few days later with a phone call to see how the install went.
This to me was impressive as many other venders sell and don't care to follow up.

 

[BoiseRob]

It is SO nice towing heavy and not caring what the fuel gauge says!

Ordered mine on 12/11. Waiting patiently. Lol

I've got a 2022 on order (who knows when it'll get built) with the 'bed delete' and have thought about doing this before I put on the flatbed but.... not sure if I want to spend the $'s but it would be so much easier with the bed off (as the one post shows).

 

[Bigtim1985]

Does anyone have a picture showing how low these sit on a 20-22 l5p? With the tank sitting 3.5 inches lower it seems to sit really low below the frame on the new trucks. I'm going bank and forth between this and an aux tank for the bed.

 

[68Ss]

Mine just arrived. What a beast. Can’t wait to get it installed. Anyone have one on a LBZ? Wondering how well it fuels at the pump?

 

[BoiseRob]

I own an '07 and other than the $200+ to fill it, it fills fine...

 

[68Ss]

Rob. Can you take a picture of it installed?

 

[ColdIronAxe]

I was referencing what my mechanic said regarding the drop. He has a Titan and liked the S&B better. The S&B doesn't sit as low because it is significantly longer than the Titan. Here's a better image of the tank. We did not use the sump since the fuel line would have been exposed to road hazards...

Dude, that paint job is awesome! Makes me want to hang out on the beach and have a beer with an umbrella in it! 🤣

SD is a hidden gem, especially that side of the state.
8-9 hours straight?! i'll be lucky to get 3-4 with as much water the wife drinks.

update on tank: as of June 14th I'm waiting for Mfg to ship the tank. I was advised to allow 15-30 business days. 😳

My wife too brother

Anyone have any idea on how to update the DTE after installing one of these on a 05 LLY?

Last I heard you can't. S&B has a programmer that they send out to do such things but this only works on Ford and possibly Dodge. I know because I called them about it. Not sure if there were working on something to eventually do that but you can give them a call and ask. Dean

Can't fix DTE or Range... My low fuel light came on with 4 gallons left in the tank so figure you have less than 50 miles to empty once the fuel light illuminates...

 

[ColdIronAxe]

When I was a teenager I had a 1987 F250 diesel. The only thing reliable on that truck was the 6.9L engine. The truck was getting it started.

Anyway, the gauge never worked I always had a sticky note with the average MPG and running mileage so I could tell when I had a 1/4 tank left. Geez, the stories I could tell with that truck.

You’d think there’s a programmer out there like Kennedy, WAMS, or whoever could reprogram the DTE.

 

[BoiseRob]

You’d think there’s a programmer out there like Kennedy, WAMS, or whoever could reprogram the DTE.

I reached out to IdahoRob from ATP and asked him if EFILive could adjust the DTE or Range. He said that all EFILIve was able to adjust was the fuel capacity at full which is helpful since Titan & Transferflow tanks require the owner to reuse the stock sending unit. The S&B tank includes a new OE style sending unit accurately setup for the new tank's fuel capacity...
