Here in Oz, the Rodeo is called a Frontera and has a 3.2 V6 petrol engine, or a 3.0 turbo diesel straight four. Sold through General Motors Holden and called Holden Frontera and Holden Rodeo. The Frontera (your Rodeo) here has a 65 litre tank (13 imperial gallons or 14 U.S. gallons.) The Rodeo here (a pick up truck which I believe you call the Pu'p?) has the same choice of engines. (In 2005 the V6 was increased to 3.5 litres). The Rodeo (pick up) has a 65 litre fuel tank except in the crew cab (four door) where the tank is only 57 litres. I have the crew cad but also use the single cab and the Frontera (Rodeo to you).
A 2000 Isuzu Rodeo has a 21.1 gallon fuel tank. The estimated fuel economy is 8 mpg city, and 21 mpg highway.
18.36 gallons or 70 liters

More than likely the fuel gauge sending unit located in the fuel tank is faulty.

Per the Haynes manual it is on top of the gas tank. You have to lower the gas tank to get to it.
21.1 gallon total capacity.
you drop the fuel tank and replace the sending unit
inside the gas tank
In recent experience, I have learned that a 1992 rodeo does not have a cut off switch and that on most the fuel pump is in the tank!
