S10 Fuel Pump attachments.

[hodag]

I am a beginner and took the gas lines off my S10 and now a year later I am not sure which are which. I looked on line for an illustrated layout, but nothing but gas line replacements. On the in tank fuel pump (looking down at it) what are the four ports. Which is input, output, etc. Also looking for help where they connect on the frame, Which line is input output etc. to the engine too. The S10 is a 1994 with a 4.3 Vortec V6. thanks.
