Fuel Gauge & Sender
The dash fuel gauge is only an indication of the on board fuel supply.
They are not exact reading instruments. Therefore, use the one third
rule discussed earlier for monitoring your fuel supply. There are not many
fi lling stations on the open waterways! The gas sender located in the fuel
tank uses a fl oat system which sends a signal to the dash fuel gauge as
to the fuel tank level.
Fuel fi lters are installed on marine engines. They are of the spin on
type similar to an automobile oil fi lter. Their main purpose is to trap
dirt particles and condensation in fuel. It is a good idea to keep an extra
fuel fi lter on board along with a fi lter wrench, catch container and
clean rags for emergencies. Never use automotive style fuel fi lters on
your vessel. Dispose of all fuel residue materials in an environmentally
safe fashion.
