Hello,
After experiencing several of the Penta fuel pump issues outlined on other threads I replaced the entire fuel pump assembly on a 5'7 GXI-H with an Amazon special. When attempting to start, the exhaust was throwing gas and the engine would sputter. I pulled the electric to the LP pump and this would at least allow the engine to run. After further exploration, I discovered that the pump was sending fuel to the manifold. This seems very odd and guessing the pump is garbage. Disconnected the line in the picture and the electric from the LP pump and it's running fine. Looking to understand what each line/vacuum is from the pump. Pictures attached...
The LP pump seems to be loading the air intake and the blue valve is pulling pressure when i put my finger on it. Pulled the hose to the vacuum and pulled the power to the LP pump and the boat's running fine. Does anyone have the purpose of each module on the fuel pump assembly? Saw several posts but don't understand the purpose of each mechanism in the assembly. Also looking to understand if the pump should be pushing gas to the manifold? Any response is appreciated. Thanks!
