Being the Leak Off Line attaches to the Fuel Accumulator, and with the tank Screen gone, it allowed unfiltered gas to it, I wonder if that may be an issue or clogged.

1) Re: Apparent rich mixture.
Check that the cold start injector (CSI) is not remaining open, due either to mechanical sticking from dirty fuel, or from being energized continuously.
If there is no fault with the CSI, the metering plunger in the fuel distributor may be sticking.
2) Unless the diaphragm in the accumulator has failed, there is no flow through the leak line.
