I have a LongRanger split fuel/water tank in my 100. Gives me about 215L diesel and 50 or so water.
The fuel gauge is the Toyota one refitted to the LR tank. As such it does not work as a full range gauge and can only be used as a guide. This more pronounced on the split tanks as the water partition is recessed into the fuel partition which prevents the fuel gauge being able to float to the top anyway. It also did not read empty in any meaningful manner.
I pulled the sender out and re-bent it so that it flags the empty light when there is about 20 litres left so I know I have some 100Kms range before I'm screwed. Takes several 100Km's before the gauge moves down from full.
The LR tanks are made of 2mm steel (water partition is stainless). I've dropped the truck off a ledge onto a rock via the tanks rear corner. Put a bit of a dent in the tanks floor but did not deform the corner or damage the welds.
My only bitch with the tank is that driving up a low range 2nd gear hill, I have had the car stall due to fuel starvation. The tank still had 30% in it on the flat which has to be at least 50-60L so I'm guessing there is no baffling to keep the fuel around the pick-up. Really annoying having to swap tanks and prime the fuel system halfway up a very muddy steep slope with a camper on the back.
Have ordered a bore scope so I can peer into the tanks guts and find out what the fuel pick-up arrangement is.
All in all its a great accessory and I wouldn't be without it. Lets you bypass the Innaminka fuel pumps
