Sounds like you did a custom build, replaced all the pieces and had this problem on initial start correct?
When the electric pump was installed was it up front and drawing through the fuel system, or in the rear pushing fuel?
I'm going to guess it was up front, basically bypassing the manual pump and drawing through the flex line connected to the hard line on the frame?
If that is the case, remove that rubber line and the line from the selector, Blow air through it from the pump end to the selector and see if the line is clear, then try the other direction. I'm thinking you have either a bad rubber line (collapsing or internal damage like the way a brake line can fail and become a one way valve) or there is something traveling the hard line.
