Fuel System Requirements - BRP Evinrude E-Tec Series Service Manual

Fuel System Requirements

Overview
Fuel systems must meet minimum specifications
to insure the proper delivery of fuel to the out-
board.
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 perma-
•
nently 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.)
INSTALLATION AND PREDELIVERY
Fuel System Primer
Outboards require a priming system capable of
refilling the fuel system after periods of non-use.
Primer Bulbs
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.
