Riva 90 ARGO - Fuel System

8 - PROPULSION SYSTEM243
8.8 FUEL SYSTEM
The fuel tank is made of berglass in accordance with ISO 10088 and is
located forward of the engine room, below the VIP cabin.
The tank is lled through two ller necks, located inside two suitable peaks
placed along the side walk-arounds of the yacht.
The fuel level is detected by a sensor and is visible by means of the control
panel, located in the main station.
It is possible to monitor the level in the tank also by means of a visual gauge.
CAUTION
It is a good rule, before each navigation, to check again the fuel level also
by means of the visual check installed on the tank ange.
NOTE
The level indicated without operating the valve refers to the last check.
CAUTION
While checking for consumption and distances, it is a good rule to always
keep plenty of margin, so as to be able to face bad weather conditions or
other possible unexpected events.
The fuel is sucked directly from the tank and is sent to the distribution mani-
fold, which supplies the engines and the generators.
The fuel sucked, before reaching the uses, ows through the water/fuel
separator lters holding impurities and separating possible water in the fuel.
During boarding, the fuel ow produces a lot of foam; if this comes out, you
might think the tank is full. Therefore, it is good to wait for a few minutes and
then top up, in order to be sure that the tank has been lled correctly.
The particular geometric shape of the tank allows the decantation of impuri-
ties in the fuel tank.
It is appropriate to ll the tank some hours before setting up for navigation,
in this way the impurities in the fuel will settle down and water will decant as
they are both heavier than fuel.
The tank is drained by means of a tap with a manually operated valve lo-
cated on the straight suction pipe up to the bottom of the tank, which allows
any deposits that may have formed to be separated.
CAUTION
The purge must never be conveyed into the bilge. If the purge acciden-
tally falls into the bilge, turn the bilge pumps off and clean them carefully.
To avoid fuel fumes, the tank has been equipped with an air vent manifold
with ame retina.
When the re-ghting system is activated, the fuel shut-off valves are closed
by actuating the corresponding tie rods.
