I have a 98 3.8L Camaro. To start off I tested my fuel pressure and found that it was a little low. Replace the fuel filter, still low. Decided to check the fuel pump next. Pulled the assemble out and noticed the the fuel line from the pump was kinked and figured this me be the issue. I replaced the hoses (internal hoses) and put everything back together, now I have NO fuel pressure. I do here the fuel pump turning on when the ignition switch is turned on. Any Ideas what I may have done wrong. I'm 90% sure i put the lines (internal to the tank) back in the right locations.

 

sounds like your mistaken and you have some lines wrong either internal or external double and triple check them some where on here i have pics of the sending unit ill try to find them for ya

see if this pic helps you its from a 95 3.4 but im thinking it should be close

 

you are most likely correct, I'll check when i get home. Any more photo would be greatly appreciated.
