Fuel gauge readings for LongRanger tank in 100 series.

Dave,

The way it is set up is not bad. I assume that you filled the tank with 40lt then checked the gauge. If you did you would have 40 lt in the tank but the usable amount will be different. The pick up pipe will be set off the bottom of the tank, about 3mm. You will loose a few litres with the fuel on the bottom of the tank that can not be picked up.
The swill pot that surrounds the pick up pipe will also exclude some fuel. The swill pot holds fuel around the pick up pipe when the vehicle is going up or down a hill.

At a guess I would say that you would have about 25lt that can be picked up. That could be between 180/220 km.

Running out of fuel is not good. Apart from the safety issue, the fuel pump needs the fuel to keep it cool and lubricated. Noting the kilometres when the fuel light comes on and then when the motor loses power because of fuel will give you an idea on how far you can go on a empty tank.

If the motor stops, because of lack of fuel, don't try and start it until the filter has been primed. To do this push the plunger on top of the filter until it has a lot of resistance. Then the motor can then be started.

I also have the 182l longranger in a 2001 TD 100s.

I have found that the gauge works pretty much as you have stated - I'm used to it now.

When the light comes on I know I still have 400km of normal driving around town left. I get 1400km out of the 182l tank and 700km out of the 90l (or is it 95l?) tank consistently.

Refilling - I've never been able to put more than 170l in the longranger, never more than 86l in the standard tank.

Plan fuel stops accordingly and you will be right on a big trip. If you are ever stuck in the middle of nowhere, with no help in sight, you could always drain the last 10-15l from the longranger and add it to the original main tank where it will be usable!

Having said all of the above, I would prefer a gauge that was accurate from full to empty. Maybe the fitters could do something but just don't want to? If you request firmly that they fix the 'faulty' gauge they may come up with an idea?

When I had the Long Ranger tank (140 l) put in my Hilux, I was told before installation that as they use the sender unit from the old tank, the fuel guage would no longer be accurate. I'm used to it now.

The fuel part of the trip computer is also way out. We no longer use it.

Same here with the LR tank in my pajero.
Empty is about a 1/4 below the last 1/4, if you can follow that.
In other words, empty is the bottom of the E.
