Need Help with Fuel lines

I think I hooked my lines up wrong. Fuel is not coming to rail. Its coming on (the pump) I have mounted the corvette filter in the rear as the original filter was and I disconnected the all the original lines. With the early set up it was all uncovered but in this set up (1990 S2) Everything is covered. What I need to know is...Which line on my vehicle is the return, which is the out line from the tank to the pump and then to the front of the engine. There are no pictures of the underside of the car labeled with which line is which on the late cars.

I know which lines are what for the corvette filter but I am not sure what to hook to them. Can someone help....any pictures of what lines are what. Again - not of the new parts but the existing lines on the car.

the fuel outlet on the tank is at the bottom, the fuel pump sits under the cover on the bottom, it then feeds through a soft line into the fuel filter and then into the 10mm steel line on the body (the larger fuel line). the return line is the 8mm steel line on the body and will return to the top of the tank.
