Greetings. This is my 1st post and I could really use some help. I have a 2003 Hurricane with a 5.0ltr Volvo Penta that is carbureted and has a single low pressure, electric fuel pump. A bit of history on the boat; I got it from a family friend after it fell off of his shore station and ended up with the motor under salt water for several hours. Boat was pulled out and all fluids changed. Fuel tank was drained and cleaned. New coil, distributor, plugs, starter. Boat sat for several months before I got it. When attempting to start the boat, a massive amount of fuel gets dumped into the carb. I had the carb rebuilt twice by two different people and same problem. There is no external fuel pressure regulator that I can find so I thought perhaps there was an internal one that went bad in the fuel pump. Hooked up a pressure tester to the fuel pump and it's putting out over 40lbs of pressure, instead of about 8 that I believe is called for I replaced the fuel pump with a new one and same problem; gas getting dumped into the carb at a tremendous rate and the pressure on the new pump is about 40 also. The new pump was specifically made for a carbureted, low pressure system. Any thoughts? What should the voltage be at the fuel pump?
