Here we go again!! Shut off

[SS Shaun]

so i was talking to a friend of mine and he said he is going to swing by and help me out and look at the floats with me. the only issue he has was looking at my car and i started it up and went for a spin. and we did the same thing WOT first second as soon as i hit the clutch to go to third it shut off. crank crank crank stop hit the gas crank and go. so he had me rev it up to about 4000 rpms and he noticed my fuel pressure was still sitting at 3 psi. He now thinks that my fuel pump might be to weak for my 750 DP. he told me its time to go to an e pump or find a high volume mechanical pump to be sitting at about 5-7 psi at those higher rpms. thoughts?
