changing from a stock fuel tank to a fuel cell.

Hey there,
so I ran into a problem on my 1993 dodge Daytona mini stock, fuel injected. I pulled out the stock fuel tank which had the pump and regulator inside of. Then, when I bought the new parts from summit I asked them where I should install everything, so here is how I have it set up. From the fuel cell to a filter then the pump, all the way to the engine, the return line then passes back to the cell and goes through a regulator before it drops in the tank. The problem is now the car dosn’t start, did I set this up wrong?

If like everyone else. Regulator should go between filter and engine.
