Fuel Delivery System
WARNING
Boating standards (NMMA, ABYC, etc.) and Coast Guard regulations must be ad-
hered to when installing fuel delivery system.
GENERAL
The main concern of a boat’s fuel system is safety; this must be achieved through a techni-
cally sound installation and constant inspection.
The fuel system, from the filler pipe to the fuel pump is the same, in principle, for all boats.
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 thank manufacturer.
Only a few points related to function and safety are listed here [Refer to boating standards
(NMMA, ABYC, etc.) and Coast Guard regulations for complete guidelines]:
1. All connections should be on the upper side of the tank.
2. The drain plug at the lowest point on the tank serves to permit the removal of water and
sediment.
3. The filler pipe outer diameter should be at least 2 in. (50mm).
