POSSIBLE FUEL PROBLEMS/SOLUTIONS
1. Engines are hard to start or rough
running- Th
is problem can be caused
by air in the fuel system or a restriction
in the fuel supply which causes a lean
condition.
Check all fuel system lines, clamps, fi ttings and fi lters for
tightness. Prime and bleed the fuel fi lters if necessary.
2. Fuel fi lter elements contain “algae” or exhibit a brown
or black color and/or show water in the fuel system.
Check fuel tank for “algae” clusters. Fuel tank may require
pumping out and a cleaning with a pressure washer or a
biocide being added to “kill” existing organisms which
may be caused by water in the fuel system and fuel tank.
Replace all fi lter elements and top the tank with fresh
diesel fuel. Prime and bleed the system. Run the engines
and check for fuel leaks and restrictions along with the
possibility of further contamination moving within the
fuel system lines and/or components. It may be necessary
to replace diesel fuel system fi lter elements several times
to rid the system of contaminants.
3. Th
e fuel tank reads low and the engines are running
rough. Th
e pick-up tubes in the diesel fuel tank have
sucked up air instead of fuel. Th
e air has meandered
through the fuel lines, fi lters and is eff ecting the engine
performance. Top off the fuel tank as soon as possible.
Also, the fuel system must be bled and primed.
Another possible result of running with a near empty
fuel tank is the same pick-up tubes sucking water into
the fuel system. Remember water is heavier than diesel
fuel and will hug the tank bottom or baffl
e areas. Take a
sampling of diesel fuel to identify water in the fuel system.
4. Recommissioning aft er 6 months of winter storage
with a full diesel fuel tank the engines are hard to start
and exhibit a diesel clatter noise.
Th
e diesel fuel in the tank may have deteriorated due to its
age. Th
e cetane value may have decreased causing more of
an explosion inside the cylinder verses a controlled burn.
To start with add a cetane booster and conditioner. If this
fails take a sampling of diesel system fuel at the fi lters.

As a last resort pump out the fuel tank and replace with
fresh, clean diesel fuel.
