I put on the new filter today and it ran for about 25 seconds and died. I filled the filter before install, I wonder if that was what it ran on? I noticed the fuel pump whine is still there. I was hoping for a clogged filter, no such luck. I pulled the tank hose and was able to draw fuel from the tank. I found both schraeder valves on the pump assembly and they both have fuel, no air.
One of the pumps is running without a whine and the other is whining. They are like my kids!

I do not know which is high and which is low unfortunately. It appears to be a single unit but one of the pumps could be replaced. I did finally get smart and pulled the arrester off and could see that when the engine runs good the spray into the carb is nice and strong. When it dies or will not start the spray is spitting or even non-existent. I have read about screens being clogged so tomorrow I am going screen hunting. The weird part is only one of the pumps seems to be in distress. I hope I do not have to fork out $700 for a pump assembly. I am still in shock over that price.
Any ideas? This seems to be very common but never with a smoking gun. A lot of issues and a lot of different fixes. Getting desperate; it is on the trailer in the driveway while the paid for slip is being used for fishing.
Very troubling!!
Thanks
