The boat died on me the other day. After a few checks I realized the boat was starving for fuel. I could disconnnect the outlet on the fuel pump, turn the motor over and nothing. It has a mechanical pump thats driven via a cam off the seawater pump. The pump is about 4 months new. It's got a clear hose that goes to the carb. and it's my understanding that if the diaphran in the pump fails fuel leaks into this line. The line is clean so that rules the pump out. The belt that drives the seawater pump is new, plenty of tension, and is not slipping so that is ruled out. At this point I started checking the lines from the tank on up. The screen on the tank p/u has no buildup or restriction whatsoever. The one-way valve in the line also seems to be working as perscribed. Every other line to the tank is flowing freely. There is a shutoff between the filter housing and the pump but it has always remained opened. The fuel filter/water separator has about five hours of use on it and I was able to blow fuel through the housing easily. In short, I could not find a reason for the problem but when everthing went back together the fuel pressure came back and it worked fine. I'm nervous to take the boat out again without pinpointing the problem first. Is there something obvious I'm neglecting to check?
