DANGER! STICKING THROTTLE MAY RESULT IN UNCONTROLLED ENGINE OR BOAT SPEED. THIS COULD CAUSE
PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH. A STICKING THROTTLE MAY BE CAUSED BY
IMPROPERLY INSTALLED THROTTLE CABLES, LACK OF CLEARANCE FOR ANY OF THE THROTTLE
LINKAGE, OR BY BINDING THROTTLE LINKAGE. CHECK ALL THROTTLE CABLES FOR PROPER
INSTALLATION AND ALIGNMENT AND ACTUATE THE THROTTLE TO CHECK FOR ANY POTENTIAL
BINDING OR CLEARANCE PROBLEMS AND REPAIR ANY PROBLEMS.
NOTE:
Ensure that the factory shift interrupt (if equipped) has been properly reconnected, is in proper working order, and does
not cause any throttle actuation problems.
8.4 Fuel Pump Installation
1. Install one end of the brass T-fitting onto the threaded adapter fitting that is on the pump. Be sure to use a small amount of
pipe thread sealer on the threads and also use two wrenches when tightening the fittings so no force is applied to the pump
body.
2. Install a 3/8" hose fitting in the other end of the T-fitting.
3. Install the 1/4" barbed hose fitting or the pipe plug into the middle opening of the T-fitting. Use the hose fitting if routing the
return line to the inlet of the pump. Use the plug if routing the return line back to the tank. See the return line installation
section for explanation of return line options.
4. Pursuant to Coast Guard regulations, the electric fuel pump must be mounted directly to the engine or within 12” of the
engine. In addition,
the pump should be mounted as low as possible
to prevent excessive noise and potential vapor
lock problems. Install the small cushioned clamp around the center portion of the pump body. Mount the pump and clamp
assembly onto the engine or within 12” of the engine using the hole provided in the clamp.

DANGER! TAKE PRECAUTIONS TO ENSURE THAT ALL FUEL LINE ROUTINGS ARE AWAY FROM HEAT SOURCES,
SUCH AS THE ENGINE OR EXHAUST SYSTEM. FAILURE TO DO SO COULD RESULT IN A FIRE OR
EXPLOSION HAZARD AND CAUSE PROPERTY DAMAGE, SERIOUS INJURY, AND/OR DEATH.
WARNING! Marine fuel systems use an anti-siphon valve. A factory carburetor anti-siphon valve may not work
properly with a
PRO-JECTION
fuel system. The user may experience high levels of noise and/or vapor
lock problems due to the anti-siphon valve being too restrictive. The anti-siphon valve should be replaced
with a high flow capacity valve.
8.5 Fuel Pump and Throttle Body Filter
1. The fuel filter should be plumbed in between the electric pump outlet and the inlet fitting of the TBI. Install the large
cushioned clamp around the center of the filter. Position the filter so the fuel hoses can be routed without kinks or sharp
bends.
