WARNING!
Hot fuel can cause burns.
Return fuel may have a temperature of up to 100°C
(212 °F). If a thermoplastic tank is used, check how
heat resistant the material is.
D11, D13 and D16
These
engines have a return fuel flow controlled by an
orifice in the engine venting nipple. At full rated engine
power fuel is returned to the tank at around 25–30 lit-
ers/minute. At a return fuel temperature of approx
70-80 °C heat emitted to the tank will be around 300W.
Note that when there is only a small quantity in the tank
during prolonged operations at maximum power the
temperature can rise further.
Fuel temperatures and flows must be taken into
account by the boatbuilder when selecting the fuel
tank. For example if a fuel cooler is necessary on the
return line to avoid excessive temperatures in the
selected tank.
