My first suggestion is "don't" for a street engine. :)

After that, there's plenty of documentation on the manufacturer's websites on fuel system design.

Ah, I'm with you.

The biggest decision is if you're going to "deadhead" the pump (no return) or add a return as there isn't one on our trucks. If deadheading, you need to pick a pump that's made for that.

The second issue is wiring - it's important to have an oil pressure switch.

It'll take a while to get the details worked out, but it's not that big of a deal. It isn't cheap, unfortunately :(

I run carter street pumps that put out 5-9psi I believe. I ran a holley deadhead regulator for a couple years then converted it to return style and fabbed up a return line. Helps keep the pump cooler which I needed in 110* phoenix summers. I set the pressure at about 5.5-6psi for the edelbrocks and 7-9psi for holleys.
