Caution!
Safety instructions for installing the fuel pipes!
• Only use a sharp blade to cut the plastic/rubber fuel
hoses and pipes. Metal fuel pipes should be cut using
an appropriate pipe cutter.
• Ensure all cuts are free from burrs and the fuel lines
are not crushed or restricted.
• The fuel line from the fuel metering pump to the
heater should be run to give a continuous rise.
• Fuel lines must be secured every 50cm to avoid noise
and/or damage by vibration.
• Fuel lines must be protected from any mechanical
damage.
• Avoid running the fuel lines where their condition and
longevity may be affected by movement, vibration or
heat.
• Do not secure the fuel lines to any exhaust system.
• Do not position any fuel connection where it could
leak onto electrical connections or hot surfaces.
• Approval must be sought from any engine
manufacturer or the boat manufacturer, before
sharing an existing fuel feed.
• The fuel must not be conveyed by gravity or
overpressure in the fuel tank.
• Withdrawal of fuel after the boat engine fuel pump is
not allowed.
Please Note!
Check tank venting.
