Without actual mpg (or km/liter) numbers, we can't tell you if your fuel economy is bad or great. How about some quantitative data? (NOT miles or km/tank - who knows how empty you run it before filling up.)
And, btw, I roughly estimate that an additional 30km/tank is an 8-10% improvement, hardly insignificant.

Then the 15.5mpg seems a little low. I get 18.5-19 around town, 20 at moderate highway speeds (45-60mph), and about 17 at freeway speeds (75mph). But, lots of people report lower than that. I think I'm privileged to have a better than average running 3.0.

My 91 4runner gets about 16 MPG highway. MPG depends on your setup (tire size, weight, filters, ect) and other factors. As Austin148 mentioned, these trucks really don't get great mileage. Even after a rebuild on my engine, my MPG did not change.

A couple of things you need to do to make sure you are getting accurate mileage numbers and not just guesses or estimates.
1) Calibrate your odometer. Drive out to your local freeway that has mileposts (or km posts). If you don't have that, you can use a GPS. Reset your trip odometer to "0" and drive exactly 10 miles. Read your trip odometer to the nearest 1/10th. If it reads 10.5, for example, your odometer is showing 5% more miles than you're are actually traveling. You'll need to divide your traveled miles by 1.05 to get actual miles.
If your odometer reads 9.5, for example, you're traveling 5% further than you think. Divide odometer readings by .95 to get actual miles.
2) Next, be very consistent about filling your tank when you are trying to calculate mileage. Use the same gas station, preferably the same pump, put the nozzle into the filler neck the same distance every time, and stop when the pump clicks off the first time. That will give you the most consistent gallon numbers. Record your trip odometer reading to the nearest 1/10th and reset it at every fillup. Adjust the odometer reading for the error found in step 1, above.
Armed with accurate distance and accurate quantity, you are now ready to calculate fuel mileage.
If you're sloppy with any of this, sorry, I won't put much stock in your numbers. It's really easy to be off 5-10% either way if you're not careful, and that is +/- 1-2 mpg. You simply cannot get useful or repeatable numbers by reading your gas gauge and calculating miles per tank, or fraction thereof. The gas gauge is not that accurate and it doesn't have adequate resolution.

15.5 mpg is not bad for city/mixed driving. I'd say it's on-par with what some friends' 3.0L 4runners got. Fuel economy really has a lot to do with driving style. If I keep my TPS number down in my vehicles, I get much better MPGs (as viewed with a ScanGauge)

You're packing some extra weight with that bumper, plus extra wind resistance with the roof rack, etc., so yeah, you're probably getting about what you can expect.
Nice looking rig, though.

so update i did the fuel test its doing 11.33 litres per 100km so in my eyes that is very good fuel consumption BUT
i don't understand why its showing 3/4 quarters to a full tank
my suspicions are
my rear shocks are stuffed and most likely sagged springs
or
my fuel float is stuffed
or
there is somthing wrong with the clusters fuel gauge
is there any suggestions on what to do next

11.33 litres/100km works out to about 18 mpg, so yes, that's decent. As far as the fuel gauge accuracy, I'm not sure it's worth the effort to fix. Just reset your odometer every fill-up and when it gets to about 250miles (400 km) head for the gas station again.
