tarp box The Fuelbox Under Tonneau Fuel Tank Toolbox Combo — Tank RetailerThe Fuelbox under tonneau tank toolbox combo is designed to fit under most standard tonneau covers. The aluminum tank toolbox combo is available in 40 gallon or 55 gallon sizes. If you have a short bed diesel truck with a tonneau cover, choose the 40 gallon size tank.

The Fuelbox under tonneau tank toolbox combo is designed to fit under most standard tonneau covers.  The aluminum tank toolbox combo is available in 40 gallon or 55 gallon sizes.

If you have a short bed diesel truck with a tonneau cover, choose the 40 gallon size tank. Canister style tonneau covers are not compatible with the 40 gallon size.

If you have a canister style (retrax or roll n lock) tonneau cover with a long bed truck, choose the 55 gallon size tank.

The Fuelbox Under Tonneau fuel tank toolbox sits below the bed rails and the lid is recessed in so it can fully open with a tonneau cover. It clears most gooseneck and fifth wheel hitches. 

The Fuelbox under tonneau tank is a universal product that can be used as an auxiliary tank, transfer tank, or both. 

*Note: All Fuelbox tanks come standard with the charcoal spray liner on the inside and outside of the tank.

Recommended Tonneau Covers:

  • Tonneau covers that are designed to remain above the bedrails will be directly compatible with both sizes (Bak Industries / Bak Flip tonneau covers will be compatible).
  • Tonneau covers with a canister design (goes below the bedrail at the very front of the cab) will not be compatible with the 40 gallon tank size (Retrax & Roll N Lock tonneau covers).
  • If you have a canister style tonneau cover, the 55 gallon tank size will potentially fit if you have a long bed truck.

Note: You must measure your pickup bed with tonneau cover to guarantee clearance.

Under Tonneau Tank Toolbox Combo Features:

  • Constructed with .125 inch marine grade aluminum.
  • 90 degree flange reinforced seams which doubles weld joint thickness.
  • Stainless steel latch and lock assemblies with a continuous hinge that is the full length of the lid.
  • Weather tight seal with unique rain channel with neoprene on the lid.
  • Legal in all 50 states for diesel fuel only & meets DOT & EPA regulations. 

Tank Sizes (notched lower length):

  • 40 Gallon*: 62"L x 23"W x 17.5"H / fits short beds*
  • 55 Gallon: 62"L x 30"W x 17.5"H /  fits long beds

Both tanks have a 53 inch lower tank length.

*The 40 gallon size has a bottom tank width of 14 inches. The lower bottom tank width enables the 40 gallon size to fit short bed pickup trucks.

Toolbox Dimensions:

  • 40 Gallon: 62 inches long x 18 inches wide x 5.72 inches deep.
  • 55 Gallon: 62 inches long x 20 inches wide x 8 inches deep.

The Fuelbox can be used in two ways:

  • As an auxiliary fuel tank for your diesel pickup. Use the Auto Fuel Controller to transfer fuel to your pickup as you drive.

Vehicle Fit

The Fuelbox Fuel Tank Toolbox Combo Under Tonneau fits the following vehicles:

40 Gallon:

  • 6.5 foot short bed: Ford, GM, and RAM
  • 8 foot long bed: Ford, GM, and Ram

55 Gallon:

  • 8 foot long bed: Ford, GM, and Ram

Choose a Transfer Pump or the Auto Fuel Controller

Option 1: Use your Fuelbox as an Auxiliary Tank

Fuelbox Auto Fuel Controller (AFC) - Auxiliary Fuel System:

The AFC computer works in conjunction with the Fuelbox tank by automatically filling your main fuel tank when it gets low as you drive and shuts off when the main tank gets near full. The AFC monitors the stock OEM fuel tank.

When the stock tank gets near 1⁄4 of a tank it will turn on a transfer pump and transfer fuel from the auxiliary tank to the stock tank. The AFC will shut off the transfer pump when the stock tank is near full or the auxiliary tank is empty.

The AFC can be set for automatic operation or it can be manually turned off
from the cab of your truck. In addition there is a manual button, where you can manually transfer fuel for up to 4 minutes.

The Auto Fuel Controller (AFC) makes the Fuelbox tanks legal in all 50 states for diesel pickups. The AFC system meets or exceeds all DOT & EPA regulations. It also meets the standards required by the VESC-22.

Auto Fuel Controllers (AFC) systems are compatible for all Ford, GM and Dodge diesel pickups.

The Auto Fuel Controller is available in two models: Digital Display Controller or Plug & Play Controller.

  • Plug & Play Controller: plugs directly into your on-board diagnostic (OBD-II) port on your truck. This makes an easier install and avoids the factory wire harness. The plug and play shows the fuel level percentage in both the vehicle tank and the Fuelbox tank.
  • Digital Display Controller: is a vehicle specific controller that is programmed for the year and make of the vehicle. The Digital Display controller only shows the fuel level in the Fuelbox tank.

Option 2: Use your Fuelbox as a Transfer Tank with a Fuel Pump

The fuel transfer pump allows you to fill other vehicles and equipment. The transfer pump is a 13 gallon per minute pump with a 12 foot hose and an auto shut-off nozzle. 

Transfer Pump Accessories:

  • Filter Kit - Adds filtration to your transfer pump.
  • Fuel Meter - Logs how many gallons you transfer with the transfer pump.

Fuelbox Optional Accessories:

  • Tie down bar - add more mounting tie down points that are easy to reach.
  • Side bed step - mounts just behind the cab, providing a faster & easier way to reach your Fuelbox.

Smells soooo good!
Oh my gosh guys! This soap smells soooo good! I have tried a few different bars and none of them were great. A lot of citrusy smelling soaps. I'm not a citrus fan. But this one? Amazing! I walk in to my bathroom a good 12 hours after my shower and the whole room smells so fresh and clean. Never has my bathroom smelled like a bar of soap unless someone just stepped out of the shower. I would buy this scent as a room sray, wax melt, candle, body mist, lotion - I'd buy it all! I typically gravitate to fresh clean scents like "clean linen" and this is great! As a bonus it is a super awesome exfoliater. Jury is still out on bumps - I only got it a few days ago, but I have high hopes. I will update my review if anything changes. (If you are on the fence just buy it!)

EATS OIL TO SMOOTH YOUR FACE
Scent: Rose, Size: 2.5 Fl Oz (Pack of 1)
GET THIS!! here's what i've experienced with this item for the past week, and what i understand about about how well this item is working and will work based on what i've previously learned/experienced after heavy use of clay masks (successfully) in the past. THIS WILL RESTORE YOUR SKIN TO PERFECT TEXTURE (no 'large pores' at all). I'M SO EXCITED. i've been using used the kojic orange bar for a long while to try to even out damaged skin tone after overuse of clinique's face brush, which bar worked until it kinda didn't (even tho i can still leave it on til it burns a bit), so now am doing the lavender bar for morning/shower + this red tube before bed. i've used them both for a week and i am beyond excited about this red tube. this creamy product eats a ton of oil out of your pores. you'll still have the same texture of clogged pores afterward but only the color of skin instead of dark dots (since the dirt is only on top, as clean oil is always coming up from the bottom of your pores). eventually, deeply cleaning our your pores WILL eliminate 'large pores' and smooth out the texture of your skin (explained below). first, getting out so much oil that the dark dots are gone after a couple of nightly uses is definitive evidence that it's getting MORE OIL than other products. some other products MAY be getting out MORE than our daily accumulation, and so will also work EVENTUALLY -- but this is FASTER. specifically, my cheeks get clean but my nose still has dots - but i'm confident this'll catch up to digging out all the dirty oil in my nose as well. SO -- i'm sure that deep-cleaning all the dirt out of pores so there are no colored dots anymore is what they mean by 'brightening'... BUT... thoroughly cleaning out clogged pores (so deep that there's no dirt) will eventually smooth out skin texture cos the pores will eventually empty completely and then just shrink small/closed/smooth (like a baby again!). i previously experienced this progress after heavy use of queen helene's clay mask. my chinks literally shrank within 2 weeks. my pores looked the same, but the curve of my cheeks just flattened into my face. it was completely wild to see. when i applied mask mud, the oil in the pores of my nose and cheeks would actually soak dots into the otherwise dry & cracked mask so i had to pack the clay on so thick that it'd take so long to dry that i'd just take a nap for a over an hour, like every night for no more than 2 weeks. i was house/dog-sitting and had nothing better to do. and then my cheeks shrank. anyway, masks are boring and time consuming (and i did them so much that i still never feel any itchiness anymore) so i satisfied myself with progress without actually finishing my skin to perfectly smooth again -- given that actors in movies do close-ups that show terribly clogged pores anyway. THIS STUFF is way easier and quicker and less uncomfortable than a mask. you only need a small amount, maybe the size of two peas, and when you rub it on your cheeks it expands into a thickness that looks like clown makeup. no joke. the more you rub it, the thicker it gets - so i just keep going til i'm super white (and rubbing it up into my forehead) and then just rinse it off with my hands. my cheek pores look like SKIN. no colored dots at all, just texture. my nose still has dark dots but i'm sure that will also clean out eventually, too. HERE'S HOW IT WILL SMOOTH OUT YOUR SKIN -- after this cleaner, i use a toner (clinique) to tighten my pores to help narrow their newly emptied space against just filling back up again. without toner, i think the pores will still naturally close somewhat on their own. i think the closing of emptied pores (with or without toner) must also press the remaining oil closer to the surface into the empty space (given that it doesn't want it there in the first place) cos there's pressure where there's oil, and no pressure where there's no oil... i mean, using clay masks caused my cheeks to shrink altogether instead of, like, ending up with deep permanent empty needle tunnels into pores that stayed wide after the oil was eaten. my cheeks shrank cos the remaining oil moved up to the top (so my pores looked the same). forreal, your pores really don't want to be so swollen with oil that the skin in your face between the pores is literally pressed up into squishy pillows on the surface of your face. so this product with 'brighten' your face by removing the dark dots of dirt at the top of your pores, which is SO MUCH OIL that your face will press oil up to the top to be deep-cleaned again -- til eventually your pores close entirely and you have baby skin again. use an effective skin-tightening toner for even faster results. so my plan is to just keep deeply cleaning out the top oil with this stuff, tightening the empty skin with toner, and letting my skin keep pushing more oil up to be deep-cleaned by this great stuff the next night. i'm sure eventually it'll get to my nose, i might even start doing clay masks again. GET THIS STUFF!!
