This ensures that there is not too much or too little fuel, which can cause issues such as poor performance, decreased efficiency, and potential damage to the engine.
The 4.3 Mercruiser engine is known for its power and reliability, but without a functioning fuel pump, these qualities can quickly diminish. Regular maintenance and replacement of the fuel pump when needed can help prolong the life of your
