Replacing the fuel tank and its filler pipe (Kalina 1118)

If a gasoline leak is detected from the gas tank, it is recommended to replace the fuel tank in the vehicle. If the fuel pump screen often becomes clogged, remove and clean the gas tank.

If a gasoline leak is detected along the junction line of the upper and lower parts of the gas tank, these areas can be soldered (it is recommended that work be carried out in specialized auto repair shops). To do this, drain the remaining gasoline, thoroughly rinse and dry the gas tank. Then seal the leak with soft solder.

It is more convenient to remove an empty gas tank while working on a lift, overpass or inspection pit.

To replace the fuel tank (gas tank) on a car, you will need: a 10 mm wrench, flat-head and Phillips-head screwdrivers.
