I've seen only a couple of people run this. Mostly the stenod crew. Does high HP fuel systems tend to flood the pump while at idle?

-8 is fine up to ~1200 engine hp....once the fuel passes through the regulator, a small amount of pressure drop in the return line is meaningless.

I agree. Unless you have a motor making big HP -8an is fine. I'm running -6 return in my Z06 and -8 in my Firebird and have no problems at all.

I mean, any downsides besides price? I can't even find a FPR -8, -8, -10 return. Looks like this one is a marine FPR.

I have a single -8 feed from pump to the motor. It splits into 2 -6 to each rail, than into a single -6 into a MagnaFuel FPR.

it exits the FPR via a single -6 and returns to the tank....

No problems here, dual Bosch pumps in parallel.

Well, I went ahead and jsut bought the aeromotive pro regulator. dual -8an intlet and -10an return.
I just wanted to know if there are any downsides to a larger than usual return line. If not, I can just change the fitting on the reg., Right?

No downsides...but if there was more fuel returning, than entering the reg...I'd be very concerned !!!
