.02   Dream or complain all you want......GM is simply not going to modify their basic design for the 1500 to squeeze a larger tank in place of the DEF tank.......spent all their design money shrinking the tank to allow space for a DEF tank option. Extra 100+ lb of fuel would require new EPA, CAFE numbers and crash testing for a larger volume tank.

 

A 24 gal tank, so what? At 16 mpg on a 24 gal tank gives a range of 380 miles, not good enough for today? At 60 mph that's 6 hours of constant driving and my bladder's full a long time before that gas tank is empty so time for a service stop anyway. And about that mileage the hood should be popped and a walk around safety check for leaks should be done anyway.

 

And distance from a gas station is no excuse.......if you run out of gas it is your own fault.

My dad's pig '65 Chrysler 383 4bbl which was wider, longer and 200 lb heavier than a 5.3l 1500 got 6-7 mpg on a good day going downhill with a 32 gal tank for a range of 225 miles..... considered about average in those days.....about the same range as a '64 Nova I6 , a lighter, smaller car with a smaller gas tank........and I don't remember anyone complaining about the range, or the price of gasoline......occasionally might get a braggard boasting he was getting 10+ mpg. So what's the big problem today?

 

Want more range, buy a Jerry can.

I think it's all part of the "dramatic weight reduction" they have been raving about.  Once that settles down see what happens...   Just my thoughts.  I'll choose range over mileage any day,

Any one out there know of a supplier making a larger capacity than stock replacement gas tank for 2019 Silverado/ Sierra 1500 4WD?  Preferably in the 32 gal + or -  range.  Thanks

I can understand the guys that are towing using a gas engine wanting a bigger tank and I think a transfer tank is probably the only option.

However with my 6.2 LTZ the tank is plenty big enough for me, 90% of my driving is highway and I can get 400 miles, I can't hold my pee any longer than that ?

They have a 28.3 gallon tank for the 1500's, it is only available in the Regular Cab with the 8 foot bed.  Don't now if it will fit in any of the others.

First we are not in 1965 - but sure wish we were for gas prices at $0.20 per gallon! 

 

For those of us who tow with our truck we want a reasonable range - at 8 mpg towing you are looking at 200 miles of range +/-, that is simply not enough.  A 36 gallon replacement tank would get you to about 300 miles - which is bare minimum.  400 miles would be ideal, just like the truck not towing.   A Jerry can requires a stop and fill, which we are trying to avoid, to keep our time of travel to a minimum. 

 

We could buy a diesel and get more range, but we don't want to drive around a 3/4 or 1 ton truck everyday and don't tow enough of a load to warrant the added torque of the big trucks diesel motor.  The Duramax for the 1/2 ton does not get any better mileage towing a 8,500 lb. enclosed trailer like I do, so that offers no additional range and worse performance on the street. 

 

So end of the day it is all about how you use your truck.  I like driving a 1/2 ton everyday for ride quality and size, I like having V8 rumble and the performance that goes with the 6.2L and 10 speed.  I have no issue paying for gas or accepting lower mileage to get what I want.  Only thing I can't get is "decent" range when towing.  That is the one compromise this thread is trying to address. 

 

GM won't be offering a larger tank, due to cost to certify.  Most aftermarket tank builders won't touch it due to EPA and CA CARB rules and extreme penalties for messing with the emission, which the gas fuel tank is a part of.   So for now we will live with poor range and jerry cans, unless we can find an alternate solution.  I am working on tank on passenger side that will transfer fuel to the main tank.  Hoping to add 20+ gallon tank there with fuel fill just like the main tank and call it a day at 46 gallons total.  Now just finding someone who can do that and make it safe is the challenge.

I carry 2 15 gallons flo n go. Use a 12v transfer pump. Takes about 10 minutes for 14 gallons. I usually fill up at the campground. But i have a 35 gallon tank

As someone who frequently drives ~600miles/8-10hr trips across my province, as well as 2hrs to and from work each day, I wish there was at least 30gal/120L tank option. Time is money. I would sacrifice 3-4" of the bed for a clean slip tank install, or maybe even the dead space around the one(or both) sides of the wheel well. That's probably all the volume that's required to make the truck reach my points of destination.

 

I like the flo n go idea as a backup but I hate the idea of unsecured fuel in the bed, in plastic containers, with poor ventilation.

Someone made a caddy tank for in the bed over the wheel hump. I also think there was a tank where the spare tire goes.

You may be able to get it to fit if you moved the fuel tank crossover.  We just pulled the 28 gal tank out of my regular cab to do a short bed conversion.  We had to go with the smaller crew cab tank and move the crossover towards the engine.

Sorry to bump an old thread, but I was wondering this exact thing.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
