54 Maintenance and Service
Fuel Storage
If fuel is stored on site:
ț Keep storage tank covered to prevent water entry.
ț DO NOT use a tank made of galvanized metal or any galvanized piping
for diesel oil storage. Diesel will react with the zinc, forming solids that
can clog fuel filters and cause engine damage.
ț Fuel stored for a long time may oxidize and form solids, causing filtering
problems.
ț Keep the area around the fill cap clean. Tilt the tank slightly toward the
drain plug area so water and sediment can be easily drained.
Generally, fuel contamination occurs as the result of improper fuel handling.
The most common types of contamination are water, dirt and microbial
growth (“black slime”). The formation of varnishes and gums resulting from
poor fuel stability or long storage (“stale fuel”) also affects fuel quality. The
best treatment for contamination is prevention by maintaining a clean storage
system and choosing a reputable fuel supplier.
