Stop in for a cup of coffee

Good morning. So, plan for tonight is disconnect the fuel line at tank and engine and blow compressed air through...or not. If flows air fine, then the thought is plugging my vent line for the tank, putting fuel feed line in a container and pressurizing the fuel tank ever so slightly to see if blockage us in the tank. So close, but so very far away....
I just stuff a rag around the air hose in filler neck and give it a couple shots. It wont build much pressure and if fuel line has a leak it will show up.
Do it outside.
I went to fire up my power wagon after it sat for a year, wouldnt pull any fuel. The pump was gummed up. A suction gun to pull fuel through pump got it going.
This year it needs a new pump.
