Has anyone seen any kit for the JK that allows you to install a higher capacity gas tank? My Jeep is a DD and it would be cool to cut down on the fill ups.

 

The best advice I can give you is to do some searching on JK-Forum (Yes, I know that finding something with search can be frustrating). The reason I say to search, however, is because I recall someone installing dual tanks a long time ago, and I recall someone else posting up a link for a company that makes custom bladders more recently.

 

I remember hearing about the long ranger, lone ranger, something like that for gas tanks in Australia for the 4 doors that added about 18 gallons of capacity.

 

Here's the thread:

The extra hidden extra tank is a good call....

 

Good thing possibilities exist, but for a DD wouldn`t the extra weight of fuel be a negative thing?

 

every 100 pounds ofadditional weight (45kgs) nets a decrease of approx 2 percent fuel milage....but your in a jeep...who cares.

 

It's actually a lot less than that so no need to worry.

 

On just about every vehicle I've owned I wanted more fuel.

I found the one in Austrailia a couple years back but it is only for diesel fuel. Over the yaers I noticed that many of the aux tanks available for many different type of trucks are usually for diesel. I think it has something to do with the different flammability/combustability.
