If it has an electric pump, you should be able to trigger the pump, and drain the tank from the fuel lines at the engine. Just need a lot of spare line, but I am sure you know that..... Sorry just noticed who the OP is. My bad.

Lance, you know enough to get that varnish out of the tank. Remove the tank, drain it all. Rinse the tank. Rinse/clean all the lines. Remove injectors and have them cleaned. Fuel rails need to be cleaned also. No other way to do this right…
I would have never even turned the key on….
