Auxillary Fuel Tank ?

[Gulfcoast]

2006 Chevy 2500 - 6.0

My Chevy 2500 has only a 26 gallon gas tank and the range is not too far when towing a trailer.

Curious...is there an auxiliary tank available for gasoline?

Ideas?

mem, you got it wrong. You can transfer gas from an aux into the main tank but you cannot hook the gas feed from the aux into the vehicle fuel system down stream from the tank. My aux pumps into the truck filler neck, whenever I turn on the pump switch in the cab of the truck.

anyway that is what I heard tell down on lot 26 where i am camping. :B

Just a thought, when GM offered the long bed, it also came with a 36 gallon tank. This will be a perfect replacement for your current fuel tank. They offered the long bed trucks during that model that you have and still do. Some junk yards have those trucks and or fuel tanks, I’m sure that you could get it cheaper there. It would be factory and basic plug and play to install. That’s what I would do.

But if the tank would fit under a short bed would GM go to the expense of making 2 tanks? Not at least offer the big as a extra cost option?

Titan Fuel tanks... I have a 51 gallon that is sitting in the same spot that the original tank was sitting in under the truck

The same here with my 52 gallon Titan. It has been in service for almost 13 years now.

My understanding was that the auxiliary tanks where you pump the fuel into the aux tank, and then manually pump the fuel from the aux tank into the vehicle tank, *are* legal for gasoline. You pretty much have to stop, get out, and do the pumping while stationary (unless you like to live dangerously). Still beats the heck out of having to pull into a truck stop, or having to juggle your fueling stops because of long stretches without anything resembling civilization + an engine that gets single-digit fuel economy.

What's not legal (AFAIK) is the kind you see on diesel TVs, where they have *auto* transfer pumps to ship the fuel from the aux tank to the vehicle tank, while it's running. The impression I got was that the DOT won't sign off on such aftermarket devices for gasoline engines, due to the explosion hazards compared to diesel.

Auxiliary tanks for gas are legal. Check Transfer Flows 40,50,75 gal. tanks for gas

Transfer flow was one of the first places I looked. The only thing they claim will fit a 2017 RAM 1500 are 40, 82, and 100(50/50) refueling tanks. I couldn't find anything that claimed to work in a 1/2 ton Ford, GM, or RAM gas pickup plumbed in to transfer or feed the existing fuel system. Same holds true for Titan tanks and a number of other popular manufacturers.

I was told by a local truck accessories shop that it was illegal, and based on my research to that point it seemed reasonable since I found lots of options for diesel and none claiming to fit gas. However, as posted by Durb, Aluminum Tank Industries does have auxiliary tanks that are listed for gas. They don't have a fitment guide, so I can't say for sure they will fit, but I will be checking in with a local distributor after Christmas to see what they can do. Amazon lists the 30 gallon tank with install kit for $594.99.

If you can live with something not tied into the fuel system why not get two of these? 230ish$ and be done with it. I had one for my boat that held 60 gallons and would top off at the marina with it. That was back when gas on the lake was 6-7$ a gallon.

We have had even a 26 gallon diesel tank on an older truck. The bottom line for us is we have to pee no matter how big the tank LOL

Well, nobody forces you to stay in the truck until you get low on gas, but it's nice to stop at someplace nicer to use the facilities instead of a stinky, noisy, crowded gas station. And it's nice that you get to pick the place to stop, not the truck.

On top of extended mileage I also find fuel at the lowest price, $2.54 - $3.09 with in 50 miles of each other. I fuel when I want not when have to plus save about $50 on an 80 gallon fill.

It's sure good to stop and walk around for a bit, it really makes the trip seem easier as we get older.

This post and the post above it seem to defend the puny fuel tanks on some trucks, especially gas hauling a trailer.
News flash, you can still stop every hour or 2 to take a leak or stretch or whatever without filling up.
For the rest (majority) of people, more fuel capacity is very welcome for a multitude of reasons, none of which will cause someone to pee their pants...

You first must decide if you want the auxiliary tank in the bed of your truck or underneath (replacing the original tank that came with the truck). Once you decide this you have many options either way

Gulfcoast, you can cut that price way way down. some folks with deep pockets just gotta have the spencive stuff.

Maybe get a reasonable priced one and just buy the transferflow decal? :B:h
