Frequently Asked Questions:
(1.)How does a Marine fuel pump work?
This fuel pump has a sensitive diaphragm in charge or receiving the suction signal from the piston cylinder. This setup allows the pump to deliver the fuel.
(2.)What are the symptoms of a bad fuel pump on an outboard motor?
When the outboard fuel pump is bad, it operates similarly to when the boat runs out of fuel. You might notice sputtering or misfiring before the engine cuts out completely.
(3.)What are the symptoms when the fuel pump diaphragm fails?

To Test a Bad Outboard Fuel Pump
Step 1:Turn Off Power
Turn off the main electrical cutoff switch.
Remove the snaps on the outboard motor upper case and take off the cowl cover.
Take the spark plug wire boot off the plug tip. Move this wire around from the opening by taping it to another part or wedging it between components.
With your socket wrench, remove the plug.
Step 2:Use a Compression Gauge Hose
Screw your compression gauge hose to the hole of the spark plug. With your hand, twist the throttle position wide open.
With your other hand, pull the rope start, or turn the starter over to turn the engine over four or five times.
Read the compression gauge in PSI (pounds per square inch).
If you are troubleshooting an electric start motor, you will need a helper to crank the engine while the throttle is wide open.
Step 3:Check Specs
Look in your owner’s manual to find the proper PSI for your outboard engine.
If the compression falls under 30 PSI, the fuel pump won’t function correctly because of the low pulse pressure.
Look to fix the compression issues first.
If the compression seems okay, you can reinstall the spark plug and perform the same test on the other cylinders.
Step 4:Check the Sump Screen
There must be enough fuel in the tank to be picked up. Additionally, check the sump pickup screen for clogs.
Blow air through the tank vent, ensuring that it is flowing freely.
You can also inspect the fuel primer bulb for leaks and cracks.
Step 5:Inspect Connections & Hoses
Examine all of the fuel connections and hoses for leaks or kinks.
Loosen the fuel filter hose clamps and pull off the filter. You want to blow through both ends to look for obstructions.
If the filter is good, reinstall it and tighten the clamps back up with your screwdriver.
Step 6:Check the Pulse Hose
Loosen the clamp on the pulse hose, which is connected to the intake manifold and fuel pump.
Make sure you have a container underneath the hose as fuel will discharge.
With an electric start, you will need a helper to crank the engine several times. Make sure your ignition cutoff is activated and the plug wire is removed.
If there is a lack of fuel discharge, you might have a bad diaphragm or fuel pump check valve.
Connect your fuel pressure gauge to the pulse hose. Crank the engine.
Normal fuel pumps will put out between five and seven PSI. Readings below this point to a bad diaphragm or pump check valve.
