Replacing the fuel tank and its filler pipe

You will need: keys "for 10", "for 12", pliers, a screwdriver with a Phillips blade.

Notes:

If a fuel leak is found in the tank, it is recommended to replace it.

If the fuel filter becomes clogged frequently, remove and flush the tank.

If a leak is found along the junction line of the upper and lower parts of the tank, these places can be soldered (it is recommended to do it in specialized workshops). To do this, pour out the remaining gasoline, thoroughly rinse and dry the tank. Then solder the leak with soft solder.

You can only solder a thoroughly washed and dried tank that does not contain gasoline vapors, otherwise the vapors may ignite when soldering.

To flush the fuel tank, use Lobomid, MS or ML detergents. Then, to remove detergent residue, rinse and steam the tank with hot water. Dry the tank thoroughly.

It is more convenient to remove an empty tank. working on a lift, overpass or viewing ditch.

To remove fuel residues, remove the fuel pump module (see "Removing and installing the fuel pump module", page 115) and pump out the fuel through the opened hole in the tank.
