Feeding the Hemi with Fuel

Mine gets it's fuel from an in-tank pump that fits though the
existing pickup hole. I posted a couple of pictures here:

I've since changed the pump outlet size to 3/8" and the return to 1/2".
The regulator / filter are up front in the engine compartment.

I'm currently running @ 7 psi for a carb setup, however I've run
it up to 60 psi to test for leaks.

I have a PWM controller designed to drop the pump to ~ 50% under
high vacuum conditions to minimize aeration from the fuel return and to
minimize pump noise. It's yet to be installed so I can't comment on
how well it works...
