Portable Fuel Bladder Tank

Operational manual

  1. Purpose and basic specifications

1.1. Portable Fuel Bladder Tanks (PFBT series) are designed to be used as basic and (or) auxiliary fuel tanks for cars, small crafts, and other motor equipment at ambient air temperature from –50°С to +50°С.

1.2. The bladder tank consists of a multilayer polymer leakproof shell and a protective fabric shell shaped as pillows, handle-straps for loading and fastening, drain/filling nozzles with a screw cap to connect the bladder tank to a stop valve and then to a fuel line or a drain hose.

1.3. PFBT series bladder tanks are manufactured with a capacity of 12 to 500 litres.

1.4. It is allowed to store and transport process and potable water in the bladder tanks (only in clean tanks that were not used for fuel transportation) at a temperature no lower than +4°С.

* Substandard size PBT can be manufactured upon request

** The sizes are given for the tanks filled on a flat surface. If the tank is placed in a confined space (box), the size and capacity of the filled bladder tank will be determined by the internal geometry of the occupied space.

  1. Installation

2.1. Bladder fuel tanks can be installed*:

* in case of installation on a vehicle, secure the tank with a sling (belt, tape) to prevent it from displacement during transportation.

2.2. The surface for the bladder tank installation must be clean, and must not contain sharp items that might damage the leakproof shell, such as glass, nails, spikes, screws, wire, etc.

2.3. Cover the protruding vehicle body parts with tarpaulin material or a tent-cloth.

2.4. In case of bladder tanks installation in confined space (insert option), make sure the the box volume complies with the the tank nominal capacity.

2.5. Do not install bladder tanks with fuel in sealed and poorly vented places, as well as at less than one meter’s distance from electric heaters or near open flame.

2.6. In case of tanks installation at open sites, it is recommended to protect the top of the tank shell from the long-term impact of direct sunlight.

2.7. Do not heat the shell above +50°С.

2.8. Prior to connecting the bladder tank to the drain, connect the valve. For that purpose, remove the cap from the drain and connect the valve with the choke applying a fluoroplastic tape. In order to connect to a fuel line or a stationary fuel tank, connect a fuel hose of a relevant diameter to the valve choke and secure it with a clamp (not supplied).

2.9. The bladder tank filling nozzle must be located on the top.

2.10. In order to bring the filler neck where necessary (deck, board, etc.), connect the choke and the filling hose (not supplied) to the filling nozzle.


    1. Do not disassemble and damage the shells and other parts of the tank.
    2. Keep away from children.
    3. Do not store the tanks near open fire and heating appliances.
    4. Do not expose the tanks to direct sunlight.
    5. Do not place filled tanks together with items that might damage the shell (knives, scissors, screw-drivers, and other sharp tools, nails, metalware, chips, etc.).
    6. Do not throw and drag the cans.
    7. Do not lift or hang the tank by the handle-strap designed to hold the nozzle during product filling.
    8. Do not heat above 45°С.
    9. Do not fill the tanks above the rated capacity.
    10. Do not pour in food products after oil products.

4. Filling and operation

4.1. Fill the bladder tank through the filling nozzle using the gas station dispenser, or using the hose (arm) from another vessel, or manually from a canister (bucket) using a funnel, to the nominal capacity indicated in the product technical data sheet.

4.2. While filling, hold the filler neck with hand carefully so as not to damage the internal leakproof insert with the gas nozzle or the funnel.

4.3. Do not fill the bladder tank above the nominal capacity and overflow the fuel through the filler neck.

4.4. After filling, cover the filling nozzle with the screw cap.

4.5. To avoid displacement and rolling over, tie the bladder tanks with handle straps and string to the vehicle body.

4.6. Fuel supply or drain may be carried out by gravity (if the drain hose level is below the top canvas shell of the tank), or by using the vacuum created by the motor fuel pump at any bladder tank position.

4.7. It is not necessary to provide access of atmospheric air into the bladder tanks (physical property of elastic shells) to drain the fuel.

4.8. In case of vapor phase formation (inflation due to overheating) inside the leakproof shell of the bladder tank, release the excess pressure of hydrocarbon vapors through the filling nozzle (Do not smoke!!! Do not use open fire!!!).

4.9. In case of fuel heating in the tank, it is recommended to stir the tank contents by swaying the shell to reduce the temperature.

4.10. Do not store filled bladder fuel tanks in living quarters and closed (not vented) premises.

5. Header storage

5.1. In order to arrange for a large-volume fuel storage, several bladder tanks can be connected into a header system using a piping manifold. Connected tanks must be of the same capacity.

5.2. Connect valve fittings of each tank to the common piping manifold.

5.3. The header pipe diameter must be no less than the tank valve diameter.

5.4. Fill and drain fuel to and from each tank separately one-by-one as usual, and close valves of unused tanks.

6. Packing and storage of empty bladder tanks

6.1. Store empty portable bladder tanks indoors or under the shelter or covered with tarpaulin material outdoors.

6.2. For the best protection of tanks during storage, store them indoors at the ambient temperature from –25°С to +25°С and air humidity not exceeding 70%.

6.3. To prepare the tanks for storage:

6.3.1. Completely drain fuel remains from the bladder tank;

6.3.2. Remove the valve and connected fittings and completely let the air out of the shell;

6.3.3. Screw the cap onto the filling nozzle;

6.3.4. To fold the tank, put it on a flat surface, straighten it, then fold it into three widths (3) along longitudinal axes at crest lines (2), then fold it into a package or a roll (5) along lateral axes at crest lines;

6.3.5. When folding the shell, keep the drain tube open to let the remaining air out;

6.3.6. When folding the shell completely, drain the remaining fuel and close the drain tube with the screw cap;

6.3.7. Put the folded tank into the supplied protecting cover.
