Tank preparation
To prepare the tank, you need to:
●
Empty the tank and clean it from any dirt if necessary
●
Remove any fuel vapors and fumes
(especially if it is a gasoline/petrol tank);
to do so you can boil some water in a separate recipient and administer the
vapor from that recipient into the tank so it could “push” the fuel vapors and
fumes out; be sure to keep the fire used to boil the water far enough from the
fuel tank (Fig 1)

●
Find the geometric center of the tank
(Fig. 2) and drill a little hole in it using
a ø3mm bit then probe the space around for any reinforcement plates or
baffles inside the tank using a piece of wire (Fig. 3);
