FUEL GAUGE/SENDER
e dash fuel gauge is only an indication of the on board
fu
el supply. ey are not exact reading instruments.
erefore, use the one third rule discussed earlier for
monitoring your fuel supply. ere are not many lling
stations on the open waterways!
e gas sender located in the fuel tank uses a oat system
which sends a signal to the dash fuel gauge as to the
estimated fuel tank level.
e new sending units feature a removable tube (B) which
inserts inside the stainless steel sender (A) without having
to remove the entire unit found in earlier units. e unit
requires as little as 3” height to remove the tube. Also, a
liquid-tite strain relief connector protects the harness.
A buna-N type oat travels the length of the sender
tube (A) as the fuel level changes. e resistors inside
the tubing read the oat level and send a signal to the
dash gauge.
As an emergency tip in the event the fuel gauge shows
no gauge activity or reads improperly:
Check the sender by disconnecting the 2 sender
leads at the fuel tank and connecting an ohm meter
between them. Make sure you zero out the meter by
rst connecting both red and black leads together and
then adjusting the meter knob to zero. is needs to be
performed to obtain a correct ohm reading. e actual
resistance between the sender leads should be between
30 and 240 ohms.

Fuel lters are installed on your marine engine. ey
are of the spin on type similar to an automobile oil
lter. eir main purpose is to trap dirt particles and
condensation in the fuel system before it reaches the
injectors. Impurities can clog up the injection system It
is a good idea to keep an extra set of fuel lters on board
along with a lter wrench, catch container and clean rags
for emergencies. Never use automotive style fuel lters
on your vessel. Dispose of all fuel residue materials in an
environmentally safe fashion.
Note that outboard models use a spin on-spin o style
fuel lter located in the a storage compartment.
It is recommended to carry extra fuel filters for
emergencies. Be sure to store them in a dry area. For
more information, refer to your outboard owner’s
manual of contact your closest Regal dealer to order
replacement lters.
