Gastank question

I have a 97 s10 and i fuc*ed the gastank and sending unit up after looking everywhere i found i like 00 blazer and got the gastank and sending unit off of it well everything looks the same but when i turn the key the fuel pump comes on as it should but when i try and start it its not putting gas in to the lines is the wireing different?

are all the lines hooked up correctly? the two smaller lines are the same size so they could be backwards...

Well the middle line is gone it was hooked up to the charcole box with i removed but it ran fine beofre the same way i extended the lines i thought mabie i mixed them up but i got a chilton and hooked everything up the way it is in there : /

Fixed
