case of direct contact. When handling diesel fuel, always wear suitable protective
gloves, avoid inhaling fuel fumes, because it may lead to poisoning effects.
The diesel fuel is pumped by the electric pump (1) through the fuel filter (2) with an
integrated water separator and a preheater to the intermediate tank (5) above the
diesel engine. The fuel pump pumps the diesel fuel from the intermediate tank (5)
through the two filters on the diesel engine (fuel prefilter and fuel fine filter) to the high-
pressure pump.
