The whole stock fuel line system runs in the following order.
The Fuel Tank to
The stock LP to
The fuel filter cannister to
The VP44, From here fuel splits in two directions
The primary supply goes to the injectors
The secondary goes to the overflow fuel line from VP44
These meet back up at a T fitting around the back of the block behind the stock filter cannister.
From there it runs back into the tank.
This assumes you still had the rail maounted LP. If you have the in take model just skip the LP stop and go right to the cannister.
Clear as mud.

fuel, like any liquid (in general) will find its own level and the path of least resistance.
If you removed the line completely - something I don't do - the fuel is coming from the LIFT Pump end of the line - this is where it was plumbed to. That's all it ever did. If you tapped off the end by the tank the fuel is likely still in the line and is somehow coming back up and out of the other end - you'll remember I stated put some compressed air on it and blow it out.
Anyway, assuming all fittings are tight and the plumbing is correct, the truck should run, the pressure should be 15psi and the idle should be smoother, easier to deal with and easier to start from cold.
Because you are in IOWA, I would assume that it gets cold there in the winter, correct? I would also assume that you plumbed the FASS into the rear of the stock cannister, correct? You will need the stock fuel heater and WIF sensor if it gets cold. Just a thought.
