I found it today. The relief valve on the p7100 pump opens at approximately 25psi. The lift pump produces a minimum of 20psi. I am going to see what the psi is then I hook it all back up, and probably just not use a regulator unless it is really high for now.
Your correct, it was 15gph. I misread that little piece of info. Thanks for pointing it out.
The fuel tank is about 15 feet from the engine. If I just used the stock puller pump then I would have some serious vapor lock problems I think. I will try it both ways though. Plus the stock fuel lines are kinda on the smaller side. I am sure I wont have the fuel pump hooked up when I am finish wiring the engine, so I can at least fire it up and bask in the glory.
Down the road I am going to build a fuel tank for this project. I have the plans already sketched out. Right now I HAVE to get it moving under its own power. Kinda on a 2 year overdue time table, just like most everyone
