I did a swap from LT1 to LS1 and it seems the bigger fuel line which I assume is the feed line fits the LS fuel rail but there is another line on the LS fuel setup where the shrader valve sits and it connects to intake but has a plastic female end that cannot connect to the other Lt1 line. How does this all work?

As far as I know, I have done work on LS1, LS3, and LS6, there is only one fuel line to the fuel rail. It has a GM quick disconnect "plastic" type connector. You can either slip a 38 hose and clamp down over this or get a AN-6 converter from summit or jegs or local race shop. The LS powered cars use a fuel system that has a regulator in the tank so only a pressure line is run toward the front of the car. If your stock vehicle had a return from the engine you will need an aftermarket Fuel pressure regulator. I use aeromotive AEI13301. Best price i have found is $128 at Jegs. remember to install the high pressure spring. good luck

Most guys use the Corvette regulator. There is a metric **** ton of info in the Conversion forum.
