I’m in at $1200. This is the bolt in replacement for the main tank correct?
How I wish for a nice, packaged, system that would provide a larger main tank and reasonably sized sub-tank; for my HDJ81. I already make my fellow road trippers cry with my range… 
Yeah, my first fillup was $0.34/gal. Man that was long ago, when air conditioning and power windows came in Cadillacs. I don't miss those days.
pics?
Last year, around Dec , I reach out to Paul Evan at Long Range for a quote for my 1991 HDJ81 , they manufactured three different types : here the breakdown:
1. 145ltr main replacement fuel tank, RRP $1100.00 AUD Part number TLC80FR.*Specify engine & transmission type when placing orders*
2. 160ltr sub replacement fuel tank, RRP $1025.00 AUD Part number TLC80RR. *Requires removal & relocation of the spare wheel*
3. 160ltr auxiliary fuel tank, RRP $1300.00 AUD Part number TLC80RAX. *Only suitable for factory single tank vehicles or for export*
this cost without shipping, also, I am not sure if it is a turn key installation.

To install the main tank, modification to the fuel sender is needed but otherwise bolt-in as I remember. Installing a sub tank in a truck that didn't have one from the factory requires the dual filler neck and LRA makes an aftermarket version. It also requires adding a transfer pump to move fuel to the main tank, the pump and the switch are also part of the kit. They will also make a 90L version of the subtank so it doesn't hang as low as the 160L tank.

These are Longe Range Automotive tanks, sorry if I'm mixing things up in this thread which was originally intended to discuss Brown Davis tanks.
Here's a pic of the modified pickup tube and float.
Are Cruiser Outfitters the same vendor as Kurt from @cruiseroutfit ? With all the outfitting of cruisers lately, I'm starting to lose track...

Lol at least they don't have expedition or overland in their name! Yes Cruiser Outfitters is Kurt/@cruiseroutfit.
I believe he mentioned subs the only one offered from this company(they claim the stock main tank mounts do not provide enough support if I read it correctly). I just need to know what's included with this sub tank before I make a decision, but am seriously interested...
linky no worky?
Did anyone ever install a brown davis auxiliary tank on a 1996 HDJ81? Any change of springs necessary given the added weight ?
Installed a LRA 24 gallon auxilary, was running Ironman constant load 200-400kg springs... But after adding the tank I had to install airlift airbags to even out the truck. Just recently I removed the Ironman Toyo25C springs /airbags and installed OME 864's, looks to be the same ride height except without the hassle of air bags.
How much was the LRA 24gallon ?? Did it come with everything needed to be up and running ? MyHDJ81 didn't come with a sub tank so I would need dual filler , pump etc.
What I liked about the Brown Davis is that it didn't need all the stuff as a traditional sub tank, it simply pumps from auxiliary to main, with an overflow back to auxiliary.
