CAUTION
WARNING
Fuel System
General
The fuel system undergoes stringent quality checks during production and then again before the boat leaves the
factory. All fittings are of the compression type and meet stringent European standards. Where two fuel tanks are
used provision has been made to use any one tank to run both engines etc. (For fuel tap positions and diagrams
please refer to the back of this manual.)
Venting the Fuel System
It will be necessary to vent (bleed) the fuel system should any work be carried out or the fuel tank has been run
empty. First, open the venting screw (A) on the fuel filter about four turns, then pump the fuel from the fuel tank
using the hand primer fitted on the fuel pump (B). The fuel should be pumped until it is free of air bubbles. If the
engine fails to start it will be necessary to loosen the fuel injector delivery pipe nuts, put the throttle to the full speed
position and turn the engine until fuel appears from all the delivery pipes. Finally re-tighten all delivery pipe nuts
and the engine will start.
Fuel Valves
Fuel valves are located in the cockpit. They control fuel flow to their respective engine(s). Fuel valves should be
turned off when leaving the boat to prevent fuel siphoning from the tank.
Fuel Fillers and Vents
The fuel fillers are located on the side deck. When filling with fuel take care not to confuse them with the water
fillers. The fuel vents are located lower down the side deck. When the tanks are nearly full, fuel may spill from
them. Inside the mouth of the fuel vent there is a fine wire mesh, this must not become blocked or you will
experience problems filling your tanks and possible difficulty with your engines.
Fuel Tanks
The fuel tanks on your Sealine are manufactured from marine grade stainless steel or aluminium alloy. The fuel
sender units and dip pipes fitted into the fuel tanks should not be tampered with unless necessary as they have
been factory tested and sealed.
Fuel Filters
The fuel filters are mounted on the forward engine bulkhead. They have drain taps mounted at their bases for
draining any water that may have accumulated in the system. This should be checked regularly, particularly when
you fill your tanks with fuel of doubtful quality.
Refuelling
1. DO NOT smoke or strike matches.
2. Switch off engines and all electrical equipment.
3. Switch off all galley appliances.
4. Switch off cabin heater, remember this can take up to 5 min. to finish its cooling cycle and turn itself off.
5. Close all portholes, door and windows adjacent to the fuel filling point.
6. Be sure the correct type and grade of fuel is used. Check your engine owner’s manual.
7. Keep the fuel nozzle in contact with the metal fuel opening at all times to guard against static sparks.
8. Regularly check fuel vent fittings whilst filing as fuel may spurt out when the tank is almost full.
In the event of fuel odour being present, switch off engine(s) and trace the source immediately. Check fuel tank
lines and joints visually. DO NOT smoke or use naked lights. Switch off all electrics at source. The bilges should be
well ventilated and spillage dried out as soon as possible. DO NOT use the engines until all vapour has been
removed. Fuel vapour is highly explosive.
Maintenance
Replace the water separator filters annually. Periodically check the copper pipe work and fittings for corrosion or
wear. Check that the flexible hoses in the engine compartment are not damaged or perished. Replace if necessary.
Clean the fuel deck vent gauze if required.
