Actually my
570 a little over two years old the fuel pump and filter needed replacing.
I replaced filter because the pump was still working.
When ever it would shut off because it got full, my guys would try to start it 10 x getting air in the fuel pump.
Then you have to take gas hose off machind and puff until it starts pumping.
Those fuel pumps usually only last 2-3 years.
Put new one on primed it until I could here it catch and push fuel, started right up.
No more puffing gas thru a hose.
