Gday guys

Just bought a 1999 landcruiser troopy can someone tell me how the fuel tanks work in these,i filled the rear tank full and 3 quarter filled the front tank.

Now i thought then when i pushed the button in on the rear tank it should flow through to the front tank but nothing happens is that how it should work or do i wait until the main tank is almost empty before pushing the button on the sub.

It must sound like a stupid question but no one told me when i bought the vehicle.

My next question is suspension the guy i bought the troopy off told me that it had extra leafs in the rear springs and rides firm.

It rides to firm with no weight in the back would changing the springs make a softer ride or do all troopys ride hard like that.

Thanks 99troopy

fuel is taken from which tank is selected it is not transfered
and yes extra leaves will give a firmer ride

The troppy draws it fuel from whatever tank is selected, it doesn't get transferred (like Patrol).
Now I've said that I think some earlier petrol models did the transfer thing, I think
Extra leaves will make it firmer when empty, but if setup right should give a better ride when loaded, A set of springs from a recognized company will improve ride quality, but there will compremise between load carrying ability and ride quality.

99 troopy,

Fuel tanks.

You would have two 90lt tanks. One under the vehicle, just behind the drivers seat, know as the main tank and one at the back of the vehicle, behind the rear wheels known as the sub tank.

When the "sub tank" button is pushed on, a fuel solenoid is opened and that allows fuel to be picked up and flow to the fuel pump. The solenoid also allows the fuel to return to the sub tank.

When the sub tank button is off, fuel is pick up and return to the main tank.

The advantage with system is if you should hole a tank or get a load of bad fuel that tank can be isolated and not used.
I have not holed a tank and as yet have not got a load of bad fuel, but it is nice to know that the tanks are completely separate.

The Troopies do have firm suspension, they are designed to carry weight and when empty can drive like a brick.
Once the vehicle has a bit a weight in the back it does change to a brick with suspension.
If you have purchased the vehicle for touring wait until it is packed and see how the vehicle rids then.
I have changed the suspension on my Troopie which has extra leafs and air bags on the rear suspension. This is because there is always weight in the back, rear storage system and the 90lt tank has been replaced with an 180lt tank.

One way to make the vehicle ride a bit better is to keep the sub tank full and only use the main tank. The cost of filling the tank might be a bit high but the way fuel was going up it could be an investment.

Further to Waynes post, I have a 76 Series wagon that is basic ley a Troopie with four doors. I have fitted Firestone air bags at a cost of $800 fitted myself, very easy. The bags fit between the chassis and diff housing so that the vehicle primarily sits on the air bags and the springs become secondary. I have found the ride has improved dramaticly, it has taken the jar out of the springs and the vehicle handles better... Regards,,,Foxhound(WA).

I have a 95 troopy and by the way, there is no warning light on the rear tank that you are getting low, but there is on the front tank. I have run the rear tank dry a couple of times (best avoided) and the most it took to fill was 83 litres. So the 90 is "nominal". I have never completely emptied the front tank, but suspect it doesn't have 90 usable litres either.
