Dual tanks & high fuel pressure???

[425 Xpedition]

Two questions.

What is the max fuel pressure for the dual tank selector vavle on 1990 crew cab?

And does anybody know of a drop-in fuel pump the can supply 45gph & 55psi?

TPI pump from a camaro will fit right in and handle your request. I can't see the splitter valve being a problem.
