No start after actuator and fuel shutoff solenoid replaced

[Husky05]

It's 23 degrees here, engine is reading 83 degrees. Can't have frozen or gelled fuel on the fuel system right now. Yes it was minus 40 overnight few days ago. I have winterized fuel and anti gel in it.

I took the supply line off the water fuel separator filter housing, no fuel came out. Seems like it will only run if I pressurize the tanks from that line.

I can't find any vent on the tanks to check to make sure they are clear.

That could possibly mean leak in fuel line somewhere? Fuel is supposed to stay in the line after shut down right?
