Fuel Pumps
General Information
FUEL PUMP DESCRIPTION/OPERATION
The fuel pump is a crankcase-pressure-operated, diaphragm-
type pump. Crankcase pulsating pressure
(created by the up-and-down movement of piston) is
transferred to fuel pump by way of a passage (hole)
between crankcase and fuel pump.
When piston is in an upward motion, a vacuum is
created in the crankcase, thus pulling in a fuel/air mixture
(from carburetor) into crankcase. This vacuum
also pulls in on the fuel pump diaphragm, thus the inlet
check valve (in fuel pump) is opened and fuel (from
fuel tank) is drawn into fuel pump.
Downward motion of the piston forces the fuel/air mixture
out of the crankcase into the cylinder. This motion
also forces out on the fuel pump diaphragm, which, in
turn, closes the inlet check valve (to keep fuel from returning
to fuel tank) and opens the outlet check valve,
thus forcing fuel to the carburetors.
CHECKING FOR RESTRICTED FUEL FLOW CAUSED
BY ANTI-SIPHON VALVES
While anti-siphon valves may be helpful from a safety
stand-point, they clog with debris, they may be too
small, or they may have too heavy a spring. Summarizing,
the pressure drop across these valves can,
and often does, create operational problems and/or
powerhead damage by restricting fuel to the fuel
pump and carburetor(s). Some symptoms of restricted
(lean) fuel flow, which could be caused by use
of an anti-siphon valve, are:
0001 Loss of fuel pump pressure
0001 Loss of power
0001 High speed surging
0001 Preignition/detonation (piston dome erosion)
0001 Outboard cuts out or hesitates upon acceleration
0001 Outboard runs rough
0001 Outboard quits and cannot be restarted
0001 Outboard will not start
0001 Vapor lock
Since any type of anti-siphon device must be located
between the outboard fuel inlet and fuel tank outlet,
a simple method of checking [if such a device (or bad
fuel) is a problem source] is to operate the outboard
with a separate fuel supply which is known to be
good, such as a remote fuel tank.
If, after using a separate fuel supply, it is found that
the anti-siphon valve is the cause of the problem,
there are 2 solutions to the problem; either (1) remove
the anti-siphon valve or (2) replace it with a solenoidoperated
fuel shutoff valve.
Testing
Install clear fuel hose(s) between fuel pump and carburetor(
s). Run engine, and inspect fuel passing thru
hose(s) for air bubbles. If air bubbles are found, see
“Air Bubbles in Fuel Line,” below. If air bubbles are
NOT found, see “Lack of Fuel Pump Pressure,” continued
on next page.
Troubleshooting Fuel Pump
PROBLEM: AIR BUBBLES IN FUEL LINE
Possible Cause Corrective Action
Low fuel in fuel tank. Fill tank with fuel.
Loose fuel line
connection.
Check and tighten all
connections.
Fuel pump fitting loose. Tighten fitting.
A hole or cut in fuel line. Check condition of all
fuel lines and replace
any found to be bad.
Fuel pump anchor
screw(s) loose.
Tighten all screws
evenly and securely.
Fuel pump gasket(s)
worn out.
Rebuild fuel pump.
PROBLEM: LACK OF FUEL PUMP PRESSURE
Possible Cause Corrective Action
An anti-siphon valve. Read “Checking for
Restricted Fuel Flow,
Caused by Anti-Siphon
Valves” preceding.
Air in fuel line. “Air Bubbles in Fuel
Line”, preceding.
A dirty or clogged fuel
filter.
Clean or replace fuel
filter.
The fuel pickup in fuel
tank clogged or dirty.
Clean or replace pickup.
Worn out fuel pump
diaphragm.
Rebuild fuel pump.
Defective (hole or crack)
check valve(s) in fuel
pump (unlikely).
Rebuild fuel pump.
Broken check valve
retainer.
Rebuild fuel pump.
Pulse hole plugged. Remove fuel pump and
clean out hole.

Troubleshooting Fuel Pump
(continued)
PROBLEM: LACK OF FUEL PUMP PRESSURE
Possible Cause Corrective Action
Hole in pulse hose
(1 pulse hose).
Replace pulse hose.
Loose pulse hose. Tighten connection.
Boost diaphragm gasket
distorted or out of place.
Check seal between
mating surfaces where
“rib” divides pulse
chamber – gasket must
align with rib; check for
distorted gasket. Align
or replace gasket if
necessary.
Fuel Pump Components (Design 1)
NOTE: In fuel pump reassembly, remember that respective
diaphragms go against the mating surfaces
of the fuel pump body, and respective gaskets are between
the diaphragms and end caps. Gaskets should
always be replaced on fuel pump assembly.
