Mounting Fuel Regulators Question

I'm in need of some opinions here.

I'm re mounting the regulators on dad's car (Hemi Cross Ram) and this is how I'm doing it. We are running two #8 fuel lines coming from the rear, 1 from each pump, so I bought a "Jeg's duel port fuel log", to mount the regulators on, then I'm going to run one line to each inlet port of the log.....
My question is since they are opposing each other would this cause reversion in the log?

This idea sounded good at the time... (when we were at Jegs in February). But now that I'm at the point where I'm ready to mount everything I'm starting to second guess my self.

Would I have been better to run the two lines into a Y block then run 1 #10 line to the log and block the one side off?

I think it depends on how big the pumps are. If they are big pumps it would be better to Y the lines coming from the pumps and put them into one end of the log, then run a return line to the fuel cell from the other end of the log. You will need a bleeder fitting on the return line.

We are running 2 Holly blacks which are suppose to be 140gph free flowing.

Thanks
