I use this pump to replace a mechanical fuel pump on a Mercruiser Alpha 1 3.0 Liter Engine . It works perfectly, and it does not flood the carburetor due to overpressure . Another thing is that since the carburetor is filled the instant you turn on the ignition, the engine starts immediately instead of having to crank and build up pressure . Great pump .
