FUEL SYSTEM TESTS
Circulation Pump Resistance Test
Disconnect the battery cables at the battery.
Use a digital multimeter with appropriate adapter
leads to measure the fuel pump circuit and coil
resistance.
Lift Pump Pressure Test
Install a 0 to 15 psi (0 to 103 kPa)
Fuel Pressure
Gauge.
Tee into the fuel supply line before the fuel
filter.
Prime the fuel system and check for leaks. START
outboard and run at idle speed. Hold gauge level
with inlet fitting and monitor gauge for pressure
reading.
Pressure should stabilize at a reading greater
than 2 psi (14 kPa).
Results:
Normal pressure:
•
Perform the
Make sure no air leaks or restrictions exist in
the fuel supply hose or boat fuel system.
Low pressure:
•
Check pulse hoses and fittings for restrictions.
•
Perform the
Make sure no air leaks or restrictions exist in
the fuel supply hose or boat fuel system.
•
Check fuel flow through fuel lift pump. Use fuel
primer bulb to force fuel through pump.
No pressure:
•
Check pulse hoses and fittings restrictions.
•
Check fuel flow through fuel lift pump. Use fuel
primer or primer bulb to force fuel through
pump.
•
Momentarily prime or squeeze primer bulb to
check gauge operation.
•
Check pulse hose and fittings for restrictions.
