My 853 has a fuel issue, looks like there must be some debris stuck in the bottom of the fuel tank or fuel line that goes to the primer bulb. I replaced the fuel filter, the primer bulb and still no fuel gets to the filter. After disconnecting the hose to the primer bulb I figured gas should be running out of the line but nothing came out. Is it easy to get to the gas tank to replace the hose or should i try sticking a coat hanger up the hose to loosen it up. thanks for any help you can give me. Brian
