I was given an old 87' Craftsman II lawn tractor with an 18hp B&S twin (917.255913)that is not getting fuel. I removed the line from the tank side of the filter expecting fuel to flow out and nothing. I tried to blow air down the line into the tank and it has a blockage. I tried pressurizing the tank and nothing came out. I ran a rod up the line to the elbow at the tank, nothing.
Here's my question: Can I remove the elbow to access the inside of the tank or will it damage the tank and/or grommit holding the elbow?
Is there a screen in the tank that could have clogged preventing pressurizied flow both ways?
Is there a check valve blocking reverse flow?
