fuel pump, pressure regulator questions

[RexDodge]

I posted this in my build thread but was not getting much traction. Let's see how it does over here. I need you guys to shed some wisdom on me, I have here the fuel tank I have installed. My son picked it up for me a couple of years ago and I believe it is out of a full size blazer. What do you guys think? The next is a picture of the sending unit pump. I have done many searches on the web and I cannot find any pressure/gpm information. I know it is for a tbi vehicle. I believe I can use it (pump) with a fuel pressure regulator set a 5.5 psi and a return line. If I mount the regulator by the tank and run the return back will it work? I'm running aluminum 3/8" line to the existing fuel line under the cab and splicing it there. I plan to run the small vent line to the smaller (5/16") line that runs up to the charcoal canister. The 5/8" line will run to my fuel filler for a vent. In one picture I am showing the (valve) that is right under the mounting flange. Is that the line I run to the charcoal canister? The other small line that empties into the bottom of the tank is where I intend to plumb my return line from the fuel pressure regulator.

everything i've seen the regulator should b at the end of the line as close as possible to the carb or ingectors

If you bypass a lot of fuel you will raise the fuel temp with every pass. I hear this can be a problem. You might want to check that out befor you go to far.
