The Nissan Patrol GQ and GU are two different iterations of the same SUV model, with the GQ being manufactured between 1991 and 1997, and the GU taking over from 1997 onwards. The fuel tanks of the two models are similar, but not identical. While the rear tanks of the two models are compatible, the long-range sub-tanks are not. The fuel filler diameter is also slightly different, requiring a reducer in some cases.

What You'll Learn
The fuel sender units are different
The fuel sender units for the Nissan Patrol GQ and GU are different. This is despite the fact that the rear tanks for both models are compatible and can be swapped with no issues. The fuel filler is slightly different in diameter, so a reducer may be needed.
The fuel sender unit is the component that measures the amount of fuel in the tank and sends this information to the fuel gauge. It consists of a float that sits on top of the fuel and moves up and down as the fuel level changes. This movement is transmitted to a variable resistor, which changes the resistance in the circuit, resulting in a change in the voltage or current. This change in voltage or current is what the fuel gauge uses to display the fuel level.
Since the GU and GQ fuel sender units are different, it is not possible to swap them between the two models. If you need to replace the fuel sender unit in your Nissan Patrol, you will need to purchase a new unit that is specifically designed for your model. It is recommended to buy a new unit from a Nissan dealership or a reputable aftermarket supplier to ensure compatibility and proper function.
In some cases, it may be possible to modify the OEM sender unit to work with a new fuel tank. This can involve extending the float arm or making other adjustments to ensure that the sender unit provides accurate readings for the new tank. However, this type of modification should only be attempted by experienced individuals with the proper knowledge and equipment.

Rear tanks are compatible
The fuel tanks of the Nissan Patrol GQ and GU models are a topic of much discussion. The long-range sub-tanks are not compatible without cutting and welding, but the rear tanks are compatible. This is confirmed by a user who fitted a GU main long-range tank to a GQ without any issues. Another user confirms that the tanks will bolt straight in as long as they are both rear tanks with coil-sprung mounts.
The Brown Davis Nissan Patrol 148lt long-range fuel tank is a direct replacement for the GQ and GU rear fuel tank. It uses factory components, such as the standard pump, sender, and fuel system, and can be installed in 2.5 hours with no modifications required.
There are also other options for replacement fuel tanks for the Nissan Patrol GQ and GU models. The Long Ranger offers a 147lt tank that replaces the rear tank and is suitable for both diesel and petrol vehicles. This tank is designed to maximise fuel usage and has baffles and a built-in chamber to avoid pickup cavitation when running low on fuel or driving on sloping terrain. It also comes with comprehensive installation instructions and a 3-year warranty.
Adding a fuel tank to a vehicle utilises the vehicle's payload capacity, and it is recommended to fit heavier-rated springs to cope with the extra weight. It is also important to consider the compatibility of the fuel tank with other accessories that may be installed on the vehicle. Some companies provide pictures of the installation to ensure a clear understanding of the product.

Long-range subs require cutting and welding
The Brown Davis Nissan Patrol 148lt long-range fuel tank is a direct replacement for the rear fuel tank of both the GQ and GU Patrol models. The fuel filler is of a slightly different diameter, but the tanks can be bolted straight in as long as they are coil-sprung rear tanks. The fuel sender units for the GU and GQ are different, however.
Longitudinal Submerged Arc Welding (LSAW) is a specific welding technique used in pipe production for oil, natural gas, gas, central heating, water supply, sewage treatment, and other similar uses. LSAW is commonly the most economical solution when operational conditions require high wall thickness due to high internal or external pressures.
Underwater cutting and welding are metalworking techniques used by underwater divers in underwater construction, marine salvage, and clearance diving applications. Most underwater welding is direct current wet stick welding, and most underwater metal cutting is oxygen-arc and shielded metal-arc cutting.
Oxygen-arc cutting, also referred to as burning, is a process in which the metal is cut by oxidizing the heated metal, which is then blown away by the gas. It can use steel tubular electrodes or exothermic electrodes, which continue to burn independently of the arc once ignited and the oxygen is flowing.
Exothermic electrode cutting is simple and easy to learn. It can cut thin metal when the power is off and can cut ferrous and non-ferrous metals of any thickness, as well as non-conductive materials like concrete and rock.
Shielded metal arc cutting cuts the metal by melting it with the intense heat of the arc, without burning it with oxygen. This method works better for carbon steel plate less than 6mm thick and for non-ferrous and corrosion-resistant metals of any thickness.
Underwater cutting and welding require greater skill and stamina than working in a dry and stable environment due to the limitations and restrictions imposed on the equipment and operator by the underwater environment.

Fuel filler diameter is different
The fuel tanks of the Nissan Patrol GQ and GU models are similar but not identical. While the rear tanks are compatible, the fuel filler diameter is slightly different. This means that if you are swapping fuel tanks between the GQ and GU models, you will need to get a reducer or something similar to account for the difference in diameter.
The Brown Davis Nissan Patrol 148lt long-range fuel tank, for example, is a direct replacement for the rear fuel tanks of both the GQ and GU Patrol models. This fuel tank is designed to utilise factory components, making for a simple 2.5-hour install with no modifications required.
However, the fuel filler diameter difference between the GQ and GU models may require some adjustments during the installation process. This could involve getting a reducer or modifying the tank to ensure proper clearance.
It is important to note that the fuel sender units for the GQ and GU models are also different. Therefore, when swapping fuel tanks, it is recommended to purchase a new fuel sender unit that matches the specific model of the fuel tank.
Additionally, there may be slight differences in the bracing through the floors of the GU and GQ models, which could impact the installation process. Some users have reported that the GQ fuel tank may hit the front and back of the floor pan when installed in a GU model, requiring modifications or the use of longer bolts and spacers.
Overall, while the rear fuel tanks of the Nissan Patrol GQ and GU models are generally compatible, the fuel filler diameter difference and other minor variations between the models should be considered during the installation process.
