Auxiliary fuel tank

[NoBigDeal]

Anyone else out there plan on adding auxiliary fuel to their JT? My plan is either a bed mount if I decide on 35" tires, or a spare tire mount if I go with 37"s.

It's something I have been kicking around. Definitely takes a backseat to some of the other plans I have though. Have to make the wife happy first if I want to keep spending money.

Yes, I was thinking the same thing. The main reason for trading my JK for a JT is for the towing and the extra fuel would be nice.

Do we know what the fuel tank size is going to be?

This may be a silly question. Why have fuel tanks shrunk to twelve or fifteen gallons? Or have they? Thanks in advance.

Depends on the vehicle. One of mine is a 22 gallon and the other is a 16.

Fuel economy “improvements”
The less a vehicle weighs the better the mileage....

Yeah, probably one thing feeding the other... improved mileage by carrying less fuel, maintaining the same per tank range.

Maybe we can put a tank where the spare tire isn't once we bolt up 37s.

Weird how competition in the marketplace is different than performance requirements.

I would like a custom auxiliary fuel tank over the truck box fender flare. That would be awesome!

With a plywood slot?

With a plywood slot?

they'll just have to make them thinner OVER the fender, but can make them as wide as the wheel arch at the bottom where they meet the bed. This way you can still have a decked setup or whatever UNDER the plywood.

i'm losing my mind, I thought i read somewhere that this tank gave an extra 4 gallons to the jl and then there was an auxilary tank.

I can't find where i read this, was i dreaming?

EDIT:I found it, lol, first line of the Roam JL post, "ROAM JL Extended Capacity Fuel Tank: 4.25 more gallons more than stock (JLU 4 door) on the main tank and another 20.75 gallons with an auxiliary tank."

So now i need to see what this auxiliary tank is all about.

I know one of the issues with going with a larger replacement tank is be able to adjust the fuel tank size in the computer. Fairly recently, when someone wanted a 55 gallon replacement, the computer would freak out if the gauge set at full for too long and would drop fuel reading to empty. Plus it messes up your fuel mileage and dte reading. That's the main reason I'm more interested in a auxiliary tank with a transfer pump.
