42C System Operations - 39
Leaking fuel is a fi re and explosion
hazard; personal injury or death could
occur.
If any fuel fi ll or vent hoses are in need of
replacement, be certain that ONLY USCG
TYPE A1 or A2 are used.
The use of any hose other than USCG
TYPE A1 or A2 could result in fuel leak-
age. Leaking fuel is a fi re and explosion
hazard; personal injury or death could
occur.
Fuel Tank Grounding System
The fuel tank and fuel fi
ll on your 42C are
electrically grounded (or bonded) to the
ground buss of the bonding system. The
grounding system is designed to prevent
the discharge of static electricity, which
could cause a spark, especially when
fueling your yacht. An authorized Silverton
Service Technician should inspect this
system at least once each year.
While fueling, a spark caused by static
electricity could result in fi re or ex-
plosion, which could cause personal
injury or death.
Fuel Distribution Hoses
Each engine has a fuel supply hose that
runs from the pickup tube in the fuel tank
to the engine. Also, each engine has a
fuel return hose that runs from the engine
to the fuel tank. The generator has a fuel
supply hose that runs from the fuel tank
to the fuel selector valve. If your 42C is
diesel powered, there is also a fuel return
hose routed similar to the supply hose.
See the photo below which show the fuel
distribution hoses at the fuel tank.
The fuel distribution supply and return
hoses, fi ttings, and connections should
be inspected often for leaks and signs
of wear, dry rot, cracking, chafi ng, or
swelling. A good way to examine the
fuel hoses is to run your hand along the
length of the hose including the fi ttings.
Small leaks will be revealed as wet spots
on your hand. If any evidence of hose
deterioration is present, have a qualifi ed
technician replace all of the hoses with
USCG TYPE A1 hoses immediately. If a
leak is found, turn OFF battery switches,
disconnect shore power, and disable any
possible source of ignition. Do not start
your engines, the generator, or any de-
vices that could create a spark. Contact
your Silverton Dealer or Customer Service
Department immediately. If hoses need to
