LWB Gas Tank in SWB Truck

[boxyjeep]

Folks on here always said this wasn’t possible.  Dude on FB posted up these pics…. Anyone tried it?

Looks like the axle might clear.

 

Is the filler neck in the correct spot?

Not my truck, someone posted in on FB.  I believe he may have used a longer filler hose to connect it.

did they share any pics of it flexed out?  how close does the axle get?

They don’t.  Can’t find the post anymore 😑

 

If I hadn’t just replaced my SWB tank I’d give this a try…

I just realized I bought a belt routing decal from you last week!

Nice!  Thank you.  DM me if you need anything else.  I can also do custom decals.

Thank you, will do.

I would love to add a higher capacity tank so I don't have to pack around a bunch of gas cans!

Yeah, I’ve thought about this a bit more.  I think Jeep planned to offer larger tanks for SWB but then decided against the option for some reason.  If you look at the drivers side frame you can see a third square hole where tank strap would go for a larger tank.

 

The main issue besides clearance is the location of the fuel filler neck.  I may get a new LWB tank and re-weld the neck location and give it a go…. You’d also need to make a small bracket to catch the j-bolt for the third tank strap.

I've got a 16 gal lwb tank that I would give to someone that wants to do this experiment in Fort Mill SC if anyone would be interested in trying this swap.

16?  SWB is 18 IIRC…. I thought LWB was 25 or 26 gallons.

Lwb was 16 or 24. The 16 is the same dimensions as the 24 but with a shorter vent tube so you can't fill it up as much. 

[boxyjeep]

Got it.   Sounds like I need to see how short I can cut a vent tube.

16/23  you might be able to get 24 in it, but it's labeled as a 23.
