Default -6 or -8 to carb...??

I am running a 900cfm C&S dual needle and seat carb and was wondering what everyone ran for feed to the carb from the regulator? I run two 15 gal tanks as this is in my boat.

My fuel system is...
-10 feeds off each tank to a Y block with a -12 feed to an aeromotive eliminator pump
-10 feed to 13224 regulator
-10 return to both tanks from another Y block

Just not sure if I should go with a -6 or a -8 to the carb, I was thinking -8 as it cant hurt.

Thanks guys!!!

Travis

-6 would work, but like you said -8 can't hurt.

they say not to run a -8 plus you could run into clearance issues on rear accelerator pump.Have you ever taken the bowl apart and looked at the diameter hole feeding into it?You could actually run a -4 ,the -8 is just holding fuel at the inlet heating the fuel as it waits to enter the bowl.
