Where is the 4.3 Mercruiser Fuel Pump Located?

The fuel pump on a 4.3 Mercruiser engine is located in the engine’s seawater strainer housing.

4.3 Mercruiser Fuel Pump Location

The location of the fuel pump in a 4.3 Mercruiser engine is critical for the engine’s performance. Without it, the engine will not be able to receive fuel from the tank, which is necessary for operation. So it’s important to know where this crucial part is located. The fuel pump in a 4.3 Mercruiser engine is typically placed near the back of the engine, just above or below its intake manifold. It connects to a small hose that sends fuel from the tank directly into the intake manifold via an electric motor. The electric motor activates when the key is turned to on and then sends fuel through a filter element and into the intake manifold where it can be ignited by the spark plugs. If your 4.3 Mercruiser has been running slowly or if it stalls while running, one of your first steps should be to check if its fuel pump is working correctly as this could indicate a blockage in its system. Knowing where it is located will help you troubleshoot any potential problems faster and more efficiently than without having this knowledge.

Mercruiser 4.3 Fuel Pump Location

The fuel pump on a Mercruiser 4.3 engine is located near the back of the engine near the starter motor. It is a black, round device with a few wires running to it from the engine’s electrical system.
