CLEANING FUEL TANK (1000 HOURS)
After prolonged use, water and other impurities accumulate
in the bottom of the fuel tank. Inspect the fuel tank
occasionally for water contamination and drain the contents
if necessary.
During cold weather, the more empty volume inside the
tank, the easier it is for water to condense. This can be
reduced by keeping the fuel tank full with diesel fuel.
CLEANING INSIDE THE FUEL TANK
1. Prepare a fuel collector to drain the fuel into.
2. The fuel drain bolt is located at the rear of the trailer
frame (curb-side). Loosen the drain bolt (Figure 56) to
remove any fuel remaining inside the fuel tank.

3. Using a pressure washer (Figure 57), wash out any
deposits or debris that have accumulated inside the
fuel tank.
