Help needed: Fuel Flow issue

[Dave in MD]

Jason,
Happy Easter to you.
There might be a pencil filter on top of the shut off valve inside of the gas tank that is completely or partially clogged. A quick but not permanent fix is to blow air back through the gas line with the valve open. Let us know what you find.

The OP posts...

"when I loosened the bowl screw to the point that it almost leaked on the outside, it would flow smoothly and rush to fill the bowl and the car would run fine for about 10-15 minutes."

It doesn't sound to me like any sort of blockage in the fuel delivery system.

I'm going with the gas cap suggestion.
