Too much taper too soon on fuel line? 73 2.0 with FI Options

[s13u74cr4]

Since discovering my supply and return lines from the SS lines PO did are reversed been working to correct that. Now have all, correct I think, routing. But, since putting gas back in, she will not start. There is a little fuel going into the new fuel filter. Maybe that is correct but I get no indication she is even attempting to start. I hear some bubbling in the tank, that is it. What I did do is add a SS taper from Tangerine. You can sort of see it on the left there under the heat duct. Now I am wondering if where I put it, with maybe 8-10” of the smaller line into the filter is causing the problem? Causing too little fuel to flow?
