Not all car owners, in particular Gazelle, are satisfied with the available fuel supply. Users solve this problem by installing an additional fuel tank. Consider the design and capabilities of the main system, as well as how to install an additional tank.
Original fuel system
On the basis of the Gazelle, we will study the features of a standard fuel supply unit. The system consists of the following elements:
- Fuel tank.
- Pump pump.
- Cleaning and air filter element.
- Carburettor.
- Separator device.
- Fuel lines.
The rarefied fuel is supplied from the tank through the line to the separator, and then to the pump. The further path of the fuel runs through the filter to the carburetor. They will improve the system by installing an additional fuel tank, re-equipping the pump and line.
Regular tanks
"Gazelle" in the standard version can be equipped with a plastic 60-liter tank or an aluminum equivalent of 70 liters. On average, the fuel supply is enough for about 500kilometers. The tank is durable, rarely requires repair. The disadvantages of containers include low capacity.
Partly solving the problem helps to stock cans of gasoline. However, it is not always convenient to refuel between settlements. Some craftsmen increase the volume of the existing tank, but this is illegal, since interventions in the fuel system are not allowed.
Problem Solutions
First you need to get permission to re-equip the fuel part of the car. At the same time, passing through customs will be difficult, since, according to the law, the fuel supply should not exceed 10 liters of the indicator declared by the manufacturer.
Possible options for improving and increasing the capacity:
- Mounting an additional fuel tank.
- Installation of a larger tank.
- Equipment of a car with several additional tanks.
The last option is used extremely rarely, as it complicates the refueling process and is fraught with a large fine when crossing the border.
How to install an additional fuel tank?
Usually, a reserve tank is mounted near a regular gas tank. To implement such an idea, a significant alteration of the entire fuel assembly will be required. This is the re-equipment of the pump and the installation of a double neck. The design can be of two types: parallel installation of additional fuel tanks or a system of two tanks connected in series.
For the correct implementation of the process, certain skills and engineering abilities will be required, since car services do not take on the alteration of the fuel supply unit. Depending on the volume of the new tank system, a suitable pump and related elements should be selected in terms of power. The price of the issue is affected by the type of additional tank. It can vary from 15 to 100 thousand rubles, taking into account the renewal of the details of the highway.
Volume increase
In addition to installing an additional fuel tank, it is possible to increase the fuel supply on the Gazelle by installing a container with an increased volume. This is where the problem immediately arises. The manufacturer of "Gazelles" produces only 60- and 70-liter tanks. By law, it is forbidden to install other modifications (if detected, a substantial fine).
In this direction, the only legal way out will be the installation of a 100-liter tank from GAZ-66. It is simply put in place of the standard model, without altering the rest of the nodes. If you want to get even more volume, all work is at your own peril and risk.
In such cases, you can use an additional fuel tank in the following version:
- Metal containers with a capacity of up to 150 liters, suitable in shape.
- Aluminum analogue for 150 liters from any manufacturer, often put in pairs. The price is around 70 thousand rubles.
- Metal variant from KamAZ for 200 liters. Such models are mounted extremely rarely due to a significant increase in the mass of the vehicle and an increase in fuel consumption.
Installation of an additional fuel tank or an analogue of an increased volume requires the installation of a more powerful pump, other pipelines and necks. This is necessary to avoid problems when supplying fuel through the highway.
Serial wiring diagram
In this case, the main and additional tank are equipped with intakes and breathers. After connecting the breather of the standard tank to the intake of the additional tank, fuel from it will be supplied to the system. When connecting, one important condition must be observed. It consists in equipping the main tank with an individual sealed filler neck. Otherwise, air will be supplied from the reserve tank due to the occurrence of an atmospheric “plug”.
If you do not want to often refuel when moving long distances without breaking the law, you need to stock up on canisters or install a 100-liter tank from GAZ-66. All other alterations require special permission and can only be used within the country, without crossing the border.

Often, motorists have come across cases when the internal combustion engine temperature sensor gives exorbitant values. But few thought about the reasons
