Fuel System Requirements
Overview
Boat fuel systems must meet minimum specifica-
tions 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 I.D. requirement.
•
“USCG Type A1” 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.
•
Permanently installed fuel hoses should be as
short and horizontal as possible.
•
Use corrosion-resistant metal clamps on per-
manently installed fuel hoses.
•
Multi-outboard applications require separate
fuel tank pickups and hoses. (A fuel selector
switch may be used for “kicker” motors as long
as it has enough flow capacity for the larger out-
board.)
Fuel System Primer
Outboards require a priming system capable of
refilling the fuel system after periods of non-use.
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.
An 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.
Fuel Filters
Boat-mounted fuel filters and water-separating
fuel filter assemblies must meet the required fuel
flow and filter specification. The filter must be
mounted to a rigid surface above the “full” level of
the fuel tank and accessible for servicing.
