Fuel system
Fuel recommendations:
The fuel used must be clean, completely distilled,
stable and non-corrosive. Distillation range, cetane
level and sulfur content are most important when
selecting fuel for optimum combustion and
minimum wear.
Engine working conditions and ambient
temperature influence the selection of the fuel with
respect to cold handling properties and cetane
levels.
In cold weather conditions, below 0 ºC (32 ºF), the
use of lighter distillate or higher cetane level fuel are
recommended. (Final boiling point maximum 349
ºC (660 ºF) and cetane minimum 45.).
In order to avoid excessive sedimentation and to
minimise the emissions of sulfur dioxide, the fuel's
sulfur content should be as low as possible. The
diesel fuels recommended for use shall meet ASTM
designation: D 975 no. 1D (C-B) or no. 2D (T-T) with
a cetane level above 42 and sulfur content not
exceeding 0.05 percent by weight.
Check for fuel leaks (with the engine running at high
idle):
Visually check unions and hose connections.
Check the condition of the fuel hoses for:
Ageing
Cracks
Blisters
Scuffing
Check the condition of the fuel tank:
Drain condensation water.
Check for cracks.
Check for leaks.
Check the mounting.
