Diesel: Aux Tank or Larger Fuel tank

[Abnmarine]

Does anyone know what size is necessary for the RDS kit? Looking at possibly purchasing Better Built 36 gal tank: https://www.lifebetterbuilt.com/products/transfer-tanks/SteelTransferTanks/29211584 but not sure what size is needed

The fill line appears to be a 1 1/2” OD. RDS makes a kit to support that.

That fuel tank is going to sit higher than the bed rails. Are you okay with this?

I thought the bed rails were 17.5" high?

There's a company from down-under called "The Long Ranger" and they have been making auxiliary tanks for installation between the framerails where it belongs. It's an additional 18 gallons of gasoline. I don't see a diesel version yet.

The aussies take their outback excursions seriously and I would put Long Ranger right up there below ARB for quality.
With over 35 gallons of fuel between the framerails, you can fit a proper size water tank in the bed.

I don’t believe they will be making a diesel version of their tank because as I understand it the diesel will not be offered in OZ.
I installed a Long Range America 17 gallon auxiliary gas tank in my glad and did a write up here...

They are also made in OZ but may be thinking of making a diesel version for the US market. Give them a shout..

It’s about 17 1/4” from what I just measured. I’d recommend talking to someone about that tank to get an exact measurement to the top of the fuel cap. Some don’t include that into their height.

Even then, I think it would still be able to fit under the roll-up Mopar tonneau that I have.

It's either that tank, or the Titan Sidekick, which also looks like it sits above the bed rail?

I’m probably just going to have one custom made. This model would work but I’d prefer it to be about 44” in length.

I thought about a custom made option, but would need to do some searching locally.

Titan makes this bulkhead kit for adding a hole into the Sidekick, just not entirely sure how it installs: https://www.titanallterrain.com/9901610

I spoke with Long Range America. Though it’s been a while they where talking about making a tank for the diesel. Minimum one can do is contact them and show interest. The tentative plan is for me to leave them my Jeep to see if they can make something work.

I am interested in an Aux Diesel fuel tank also. I have used Jerry cans in the past and would like to go in a different direction this time. I read through the posts on this thread and others, and it does not look like there is a solution yet. Has anyone found anything new or heard of anything coming? Thank you.

I have not seen or heard anything regarding a movement in this area. The more that I work on this vehicle. I also notice how difficult it would be to fit something down there. I know removing the spare tire would be an option. Albeit not ideal as I would prefer to keep all weight before the axle.

Thank you for the reply. maybe something will come up, or it may have to end up being a custom thing.

No part # the tank was custom made and installed by aero tank. Super simple open valve feeds stock tank you can use 100% of bed tank 35 + gal I fill every 6 to 8 weeks jus love it. Aero has my measurements:

That photo of your aux tank install is the best mod I've seen on a gladiator. respect for putting your invoice for us.

I plan on using a Titan Sidekick:

And then using a valve tapped on the bottom of the tank, then running a gravity line to the OEM filler neck with a "T". I will also have a "T" near the Titan tank to tap diesel for my diesel heater. What could go wrong?

I got a 40 gallon Transfer Flow transfer tank for my Ecodiesel. I was told it’s the best quality tank on the market. I also added an in line fuel filter, digital fuel meter and an automatic nozzle.

I love it. I can go a month without gas stations, or go off-roading without even thinking about gas stations.

I’d be interested in a bed gravity fed system. However, if removable would be better. I do use my bed quite a bit for truck stuff and it would likely be in the way for a lot of it.
