I'm running an Aeromotive SS pump. Have 100 micron inline filter between the tank and the pump, and a 10 micron filter before an adjustable regulator. I run a return line back to the fuel cell. Here's what I experienced with this setup:
1) The Aeromotive pump is noisy - WAY noisier than the Comp pump I had on originally
2) Summit Racing sells a house brand version of the inline filers with replaceable cartridges and it is a nice product - and competitively priced
3) The return line needs to be ample size to avoid becoming a restriction. My return line is 1/2 inch and should probably be bigger
4) A Chevy 3-prong oil pressure switch fits in the stock location on RB engines and can be wired into the circuitry to kill the pump during sudden oil pressure loss, but you'll need to bypass this during starting
