Default Slow start, loss of power, misfire HELP

My 2001 automatic s4 has been running like **** for months now, the fuel pump went out so I was hoping that it was just bad for a while and it would run great once it was replaced. So I replaced it (wasn't oem by the way had a higher LPH rating, just had to re wire it) and now it starts really slow, takes longer to start the longer I leave it, I don't know a ton about audis but it sounds like the fuel line may be losing a small ammount of pressure?? When I replaced the fuel pump I threw away the one time use clamps and put on the cheap screw on clamps, would it be worth it to take out the pump and put on better clamps and make sure everything is perfectly sealed? I don't have the right tools so it takes forever
Thanks for your help!!!

Also im not sure if I put the fuel pump housing assembly thing back in right, when I took it out I had to turn it like 1/8th turn then pull it out, when I put it back in I got it to stay locked down but I cant get it to turn to the exact spot it was at
