FUEL SYSTEM
REQUIREMENTS
Overview
Fuel systems must meet minimum specifications.
These requirements must
be
met to insure the
proper delivery of fuel to the outboard.
The
guidelines established by the ABYC and U.S.
Coast Guard
should always be followed.
•
Permanent fuel tanks must
be
properly vented
outside of the
hull.
•
Remote fuel tank gas fills must
be
grounded.
• Permanent fuel tank pickups should have the
correct anti-siphon
valve installed to prevent
fuel flow if a leak occurs
in
the fuel distribution
system. Refer to ABYC Standard H-24.
Fuel Hose
All fuel hoses must
be
designated as fuel hose
and approved for marine use.
• Use only fuel lines (or copper tubing) that meet
the outboard minimum
1.0.
requirement.
• "USCG Type A
1"
fuel hose must be used
between permanent
fuel tanks and motor well
fittings
on
inaccessible routings.
• Use "USCG Type
B1"
for fuel hose routings
in
motor well areas.
• Use corrosion-resistant metal clamps
on
perma-
nently installed fuel hoses routed below decks.
• Multi-outboard applications require separate
fuel tank pickups. Install separate fuel hoses
from the
fuel tank to the outboards
in
multi-out-
board applications.
INSTALLATION AND PREDELIVERY
FUEL SYSTEM REQUIREMENTS
Fuel System Primer
Outboards require a priming system capable of
refilling the fuel system after periods of non-use.
Primer Bulbs 2
Primer bulbs that meet the outboard's minimum
inside diameter
fuel line requirements are used on
most outboards.
Install the primer bulb
in
the fuel supply hose as
follows:
•
The primer bulb should
be
installed
in
an acces-
sible location.
•
The arrow on the primer bulb must point
in
the
direction of
fuel flow.
•
The fuel primer bulb must be positioned
in
the
fuel supply hose so the primer bulb can
be
held
with the arrow pointing "up" during priming.

Marine Primer Pump
The alternative to a primer bulb
is
a U.S. Coast
Guard approved marine primer pump.
Electric
primer pumps offer the convenience of outboard
priming from a dash-mounted momentary switch.
