Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Normal fuel pressure on your LS should be right at 30 to 65 PSI and if you are sure the filter is clear then you are likely looking at a defective new pump. I have enclosed the test step to check it as well as the jet pump in the link below, copy and paste the link to open and view the steps.
