Does anyone know if there a company out there that makes a larger fuel tank replacement for the 2014+ 1500's? Everything I googled was for 2500 Diesels or 2500 Gas trucks.  I wouldn't mind a 35 +/- fuel tank on my truck.  I drive a lot for work and seems like I'm always filling up with 18-20 gallon fill ups.  Lot of the ford guys at work have brand new '18 F150's and they have 34 or 37 gallon tanks. I rather replace my gas tank vs. drive a ford.  But at some point, the ford trucks are offering the right options on the lots...  i'm fighting the good fight.  Need a larger fuel tank.

Subscribed. I'd like to know as well. Filling up twice a week is not fun, and with hurricane season approaching it would be great to have a larger tank.

 

I'm assuming if a larger tank is possible there would need to be a way to reprogram the computer to be able to reestimate the miles to empty.

I dunno if I would be willing to spend the $$ but, yeah it would sure be nice... I also drive a lot for work and personal and I fill up about 2x a week as well... Better than my wife's Malibu - that thing only has a 13 or 14 gallon tank!

My old car had a 18.5 gallon tank and I was getting about 25 mpg combined. Now I have a 26 gallon tank getting 15mpg combined. It's only a 72.5 mile difference between the two, which is one extra day of commute, but I feel like I'm filling up every 3 days instead of every 7. Maybe it's my heavy foot, maybe I have a leak :P

Gasoline is listed as "flammable" and diesel is listed as only "combustible". There is no application for an auxiliary gas tank, (like in the bed) for a gas anything. You can add a bigger integrated tank though. Been there and done all that.

No one makes one for the 2014+ 1500s. You can get a titan aux tank that replaces your spare tire, or some sort of in bed tank. There just isn’t room due to the frame crossmembers.

You may want to check to see if the tank from a 1500 Long Bed will fit a regular bed truck.

I'm looking for a factory replacement fuel tank.  The other option is do a fuel tank with a 12V pump in the bed.  I don't fill-up any equipment at work, so I really don't need a transfer tank in the bed.  I drive mainly city so I'm averaging about 14mpg.  So it's about every 300 miles per fill-up.  Every 4 days.  If I'm towing or doing extra trips/errands it's about every 3 days.  This is one more item the F150 has over the Silverado.  dammit.

Does anybody have any actual pictures of the 34 gal tank from the long beds (GM part # 22772345 )?  Standard bed trucks have gobs of space in front of the 26 gal tank if you relocate the EVAP canister.  There's certainly room for a much bigger (longer) tank under these trucks.  It wouldn't surprise me if the 34 gal tank fit with some modifications.

 

Does anybody have a picture of one so we can compare their shapes?

Sorry to revive this thread, but starting to dig in and do some research myself....

 

GM Part Number 22772345 on GM Parts Direct shows it fits 2014 - 2018 Silverado/Sierra 1500.  It shows all trim options.  I have a 2016 GMC Sierra SLT short box, the SLT doesn't come in a long bed.  Sounds to me this fits all models. 

 

Has anyone given it a shot and got the 34 gallon tank to fit?

You mean the 8ft bed as the long bed, right? My 18 SLT Crew has the 6.5ft bed

I also have the CC standard bed, and would love the larger tank if it just fits.

Anyone figure out if the 34 gallon tank fits in a 6.5 foot box?

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
