6-7...Just so i know we're on the same page:

1)Fuel line leaves the tank and enters the pump which is mounted near the tank.
2)Return line leaves the pump and goes to the tank or the pump by itself-no return line?
3) line runs to the fuel rail and dead ends at the rear of it.

Fuel line goes from the tank to the pump.
Pump has two outlet ports:
First is a return port that is plumbed right back to the tank
Second is a fuel supply line to the engine, goes up the frame rail of the car to a deadhead Holey fuel regulator.
All lines and ports are 1/2" in pump and in regulator.
The pump is a Mallory #5250, if you want to look it up. I'm guessing the literature from Mallory can explain it a whole lot better than I can.
