Changed the fuel lines - did a careful job - only gentle bends. When I cut the 10 year old hose open, was surprised to find it in good shape - slit it in half, bent it both ways back onto itself - no cracks, loose rubber or anything like that.
Still the same problem - started great & ran great for about 20 minutes and RPM started dropping off. Turned around and headed back - as it started coughing and wanting to die, I pumped the throttle and got a little more out of it. That tells me it
must be a fuel problem - right?
I put some air pressure on the fill tube and got nice air flow out of the vent, so I don't see how it could be bad venting causing a vacuum to build up in the tank.
Oil doesn't smell of gas so fuel pump not leaking into crank case but I can't think of anything it could be at this point but the fuel pump???
Before I order a fuel pump, is there anything I'm missing? Remembering back 10 years when I got the boat because it was doing exactly the same thing, I replaced both the fuel lines and the pump before running it and distance, so it could have been the problem then.
Found this pump for a lot less than other prices I've seen - anyone know anything about this supplier or the product?
