GENERAL INFORMATION
Notice to Installer
Throughout this manual, “Warnings” and “Cautions”
(accompanied by the International Hazard Symbol)
are used to alert the installer to special instructions
concerning a particular service or operation that may
be hazardous if performed incorrectly or carelessly.
Observe them carefully!
These “Safety Alerts” alone cannot eliminate the hazards
that they signal. Strict compliance to these special
instructions when performing the service, plus “common-
sense” operation, are major accident prevention
measures.
WARNING
Hazards or unsafe practices which could result in
severe personal injury or death.
CAUTION
Hazards or unsafe practices which could result in
minor personal injury or product or property damage.
IMPORTANT: Indicates information or instructions
that are necessary for proper installation and/or
operation.
Experience gained over the past several years has
shown that marine engines fi tted with electronic fuel
injection (EFI) require carefully integrated fuel delivery
systems. More specifi cally, the fuel tank, fuel supply
and return lines, fuel fi lters and all their associated
valves and fi ttings must be considered an integral part
of any fuel injection engine package. This may require
changes in both fuel system components and/or layout
to assure compatibility and 100% customer satisfaction
with the latest EFI engines.
Any new or re-power application involving the
replacement of a non-EFI engine with an EFI engine
may require a new or modifi ed fuel delivery system,
from the tank to the engine, for proper operation. This
installation manual has been published by Crusader
Engines to aid installers when installing the products
described herein.
It is assumed that these personnel are familiar with the
installation procedures of similar products manufactured
and marketed by Crusader Engines. That they have
been trained in the recommended installation procedures
of these products which includes the use of mechanics’
common hand tools and any recommended tools from
other manufacturers.
We could not possibly know of and advise the marine
trade of all conceivable procedures by which an
installation might be performed and of the possible
hazards and/or results of each method. We have not
undertaken any such wide evaluation. Therefore,
anyone who uses an installation procedure and/or tool,
which is not recommended by the manufacturer, fi rst
must completely satisfy himself that neither his nor the
product’s safety will be endangered by the installation
procedure selected.
All information, illustrations and specifi cations contained
in this manual are based on the latest product
information available at the time of publication.
