How long do marine fuel pumps last?
How long do marine fuel pumps last?
Fuel pumps have been known to last for over 200,000 miles in some cases. After 100,000 miles, the failure of the pump is likely enough that if you are replacing a major part in the fuel system nearby, it may be advantageous to replace it at the same time.
How much does a fuel pump cost for a boat?
The average cost for a Mercury Mariner fuel pump replacement is between $698 and $726. Labor costs are estimated between $107 and $134 while parts are priced at $592.
Does a boat have a fuel pump?
A fuel pump is an essential part of your boat motor, as it helps move the fuel from the tank to the fuel injection system. These pumps come in a wide variety of styles and specs, and they can greatly affect the way your motor burns fuel, and subsequently, how much power your engine generates.

How much pressure does a fuel injection pump have?
Pressure-Packed Fuel Injection. Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch).
How do I check if my outboard oil injection is working?
That test is with the engine running checking voltage with a peak reading volt meter. You must have a peak reading volt meter for this test. A regular meter will not read the correct voltage. By eliminating the motion sensor that tells you the pump is working. If the motion sensor is good then the module is bad.
How does an outboard fuel pump work on a truck?
This setup allows the pump to deliver the fuel. The fuel pump on an outboard motor works differently than the one found in your car or truck. When the cylinder leaks, the pump pulse signal isn’t strong enough to get the right amount of fuel to the cylinder. Thankfully, outboard fuel pumps don’t fail often.
What kind of fuel pump does a marine engine use?
There are mainly two types of fuel pump used in marine industry; the jerk type and common rail injection system. A conventional marine diesel engine use a bosh jerk pump to inject fuel into combustion chamber. It contains a single piston structure called plunger which operates; based on the cam profile.
What kind of fuel injection does a MerCruiser use?
Many contemporary MerCruiser engines employ electronic fuel injection, or EFI, that takes the place of carburetors used on older engines. The components consist of a throttle body, intake manifold, ECU module and sensors. Electronic fuel injection delivers a fuel and air mixture to the engine with more efficiency than carburetor fuel systems.
How do you add EFI to a MerCruiser?
Attach the new fuel line that connects between the pump and the new EFI throttle body. Reconnect the original wires to the new pump. Mount the EFI throttle body with fuel injector on the intake manifold. Connect the new fuel line from the fuel pump to the fitting on the injector.
How to check the timing of a fuel injection pump?
Turn the engine so that the unit to be checked is toward the TDC of compression stroke (plunger upstroke) so that hair line marking on plunger and pump body are coincided. When hair lines are coincided, stop turning and check the mark on the fly wheel whether timing is correct or not.
