Fuel System Requirements - BRP Johnson J30TEL4SUA 2007 Service Manual

Fuel System Requirements

Overview
Fuel systems must meet the minimum specifica-
tions. 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 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.
•
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.
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.
INSTALLATION AND PREDELIVERY
•
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.

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.
The Evinrude/Johnson Fuel Filter Assembly,
P/N 174176, meets all requirements for a water-
separating fuel filter.
