Has anyone had any experience with S&B Filters' replacement fuel tanks? I recently learned S&B was making offering these when I had called a local diesel shop inquiring about the Titan tanks.


I've had nothing but good experiences with the S&B products I've used before, but the fuel tanks are new to me.

We'll be towing a 5th wheel soon and having the extra fuel capacity would be beneficial. It can be difficult to find fuel stations large enough to accommodate a large trailer once you get away from the interstates out west.

I have one on order... The selling point for me was the use of a new GM OEM sending unit so the tank volume always is correct on the fuel gauge...

Cool, keep us posted if you don't mind please. The tanks for the L5P do not come with a new sending unit, but instead the OEM unit is removed from the factory tank and reinstalled with a new float in the S&B tank.

Install seems pretty straight forward.

Yes, keep us posted. I know they are out of stock right now, but we plan to upgrade when they get more in stock.

Looking forward to your thoughts both on the install and on the end product once installed.

Same here ...keep us posted. I was going to make this mod, however I have heard mixed comments on the results. Would like to know how your gage reads, as well as any other issues that may result.

That's my hang up as well - not being able to reprogram for the larger tank volume like can be done on the Fords.

From what I've read, the DTE and fuel level will be slightly inaccurate. The MPGs will still be accurate.

The fuel level is likely to stay on Full for longer, eventually dropping off after many miles have been driven.

These are the things I've read about the Titan tank - not sure if the S&B will respond the same way since it has a different float to better read the fuel level.

I just really wish there was a way to reprogram the truck for this change. Even still, I'll probably still do it. Fill ups will suck, but when I'm not towing having a 1000+ mile range will be awesome!

I ordered the tank today from S&B. It's on backorder, but at least this gets my a spot in line. No indication how long the tank is expected to be on backorder.

Coincidentally, I noticed that Titan Fuel tanks has raised its pricing. The Titan XXL for shortbed GMC/Chevrolet is not $1269, which is $20 more than the larger S&B tank.

I would prefer a Transfer Flow tank since that is what I will have in the bed but they don’t appear to offer an OEM replacement for our trucks. Not crazy about not being able to reprogram the miles to empty but whatever. S&B told me most orders were shipping about three weeks after order date. That is for a 62 gallon tank for a short bed. Not sure if they offer a bigger tank for long beds.

That's the point for S&B using a OEM factory sending unit. No need to reprogram fuel usage...

DTE on the DIC will be off, but the MPG value should be accurate. DTE will only be inaccurate because the truck ECM/BCM won't be aware of the extra capacity.

The new/extended float for the 2020+ tanks should help with keeping the fuel gauge accurately reading. Except whereas on a stock tank 1/4 tank = ~9gal, the S&B 1/4 tank = ~15.5 gal.

I believe that's only on the first couple of fill ups. The computer will learn the new 1/4, 1/2, 3/4 & full miles after several cycles. I guess I'll find out after my install in a couple of weeks...

It'll sure be easier to add the Schaeffer fuel treatment since their ratio is 16oz/125gal or 8oz/62gal...

That would be great if the 2020+ does that too. With an approximate 1200 mile range, it'll take me a little while to run through a few tanks unless we're towing!

Keep us posted. I’m very curious to know if it will relearn.

My tank was delivery yesterday despite the backorder status. It is an impressive piece and seems worthy of the S&B reputation.

Now I just need a truck to put it on!

Finally had time to get to the tank installed today. Did it at home with the rear of the truck up on jack stands. With the help of my good buddy, we were able to get it done without any major problems - except I did damage one of the clips on the supply fuel line. I found a nearby dealer that had the line in stock and my wife ran to pick it up for me. Not a big deal at all, really. And despite the cost of the replacement line, I’m still way ahead of paying a shop to install the tank.

The tank is a tight fit - S & B really used as much space as they could. I was also happy that it still cleared the Air Lift air bag too.

It’s a 2 person job and it’s not hard. Some parts are awkward, but you come up with creative ways to remove the old and install the new.

Anyway, it really doesn’t hang down much lower than stock. Maybe 1” or 1.5”?

Here’s a picture of the completed install.

Can’t wait to hear your honest feedback. Like others have said, I am particularly interested in your feedback on DTE and if the gauge reads correctly.

This would be perfect for those of us traveling anywhere north of Flagstaff Arizona where good diesel if hard to come buy.

I still have not reached the time to refuel after 6 weeks and that includes towing our 11k# TT 90 miles into the mountains. I still have just under a 1/4 tank left. We're heading to Spearfish SD on the 18th so I'll be able to see how far I can go towing the trailer. The only down side is our first stop is near Pinedale WY and they're still pumping winter diesel...

Any report on gauge functionality yet?
