^^^ That works too!^^^ did that with some AQP socketless and a Earls over clamp on my old setup. One thing I did find out about using stock feed for return is if you add another pump and increase the feed line diameter from the tank to the rail you have to increase the return line diameter to match atleast the size of the feed or the fuel in the return line cavitiates and chatters from excess pressure when it's priming, purging, or idling. -6/-6 Y to -8 feed off of dual walbros with an OEM return and that thing sounded like a beehive was under my car.

I actually don't hear any cavitation at all, and my fuel pressures drop properly in vacuum... I'm running -6/-6 Y to -10 feed.
-
I did find when using the stock feedline as the return line not to use a 4an 90 degree elbow to bring it back into the fuel hat. it raised the pressure to 60 base. I changed it out to a 6an 90 degree elbow and it was all good. Just fyi.

yep, I'll be using 3 6an elbows at the fuel hat. Didn't think that 4an would be enough. Stock fuel feed line looks already a bit small.
