1.5.1 Fuel supply
1 FUEL TANK
Fuel tanks should be made of appropriate material such as
(stainless) steel or plastic. Steel tanks should not be
galvanised or painted inside. Condensation can occur in
metal tanks when temperature changes. Therefore, water
accumulates at the bottom of the tank and provisions
should be made for the drainage of this water.
The tank will need a filling connection, a return connection
and an air ventilation connection which will require
protection against water entry.
Some official regulations do not allow connection points at
the base of the fuel tank; in this instance connections are
to be made at the top of the tank with internal tubing down
to a few cm above the bottom of the tank.
