Fuel Delivery System
Recommendations
WARNING
Boating standards (NMMA, ABYC, etc.) and Coast Guard regulations must be ad-
hered to when installing fuel delivery system.
The Fuel Tank is an integrated component of the boat. Refer to the special information on
service and maintenance, which you have received from the tank or boat manufacturer.
NOTE: On Ski Boat Applications: If during testing for a particular application, you experi-
ence fuel starvation in sharp high speed turns, baffles or a fuel sump may be needed in the
tank to help correct this condition.
All fuel lines must be well secured. The holes where the lines run through the bulkheads
should be carefully rounded off or protected with rubber grommets. This prevents damage
to the lines from abrasion.
The following, but not limited to the following, additional fuel connection related points, ap-
plying to all engines unless otherwise stated, must be considered. Refer to boating stan-
dards (NMMA, ABYC, etc.) and Coast Guard regulations for complete guidelines.
1.
Fuel pickup should be at least 1 in. (25mm) from the bottom of fuel tank to prevent pick-
ing up impurities.
2.
3.
Fuel lines used must be Coast Guard approved (USCG Type A1).
On Multi-Engine Gasoline Installations: It is best to use a fuel pickup and supply line
for each engine. If a single pickup and line is used, line must not be smaller than 1/2 in.
(13mm)
I.D.
4.
5.
Larger diameter (than previously specified) lines and fittings must be used on installa-
tions requiring long lines or numerous fittings.
Fuel line(s) should be installed free of stress and firmly secured to prevent vibration and/
or chafing.
6.
7.
Sharp bends in fuel lines should be avoided.
A flexible fuel line must be used to connect fuel supply line to fuel inlet fitting on engine
to absorb deflection when engine is running.
