If its internaly gated...I guess I can see that being a possibility

Yeah.

Re:Stock fuel pump for my set-up?

On a D will normal <12psi boost, the stock pump is ok.
I noticed on Steves (88dx) B16, T3, 450's and Uber, that his stock pump was dropping pressure up top while running 10-12psi. We were still able to get the fueling inline (no WB, but the plugs said so) with Uber pushing pretty high duty cycles up top. Same thing happened w/ my B16 on 450's, stock pump and 10-12psi. Sooo, D's are OK, B's need a pump after 12-14psi.
