Update, purchased a pair of Aeromotive bypass regulators from Smokin Gun (Gordon)! What would you guys recommend for line size? The pumps are 10AN inlet and outlet, I believe the regulators are 8AN inlet and outlet with a 6AN return? Not positive on that though.. I was going to pull 10AN out of the tank to the pumps and 8AN from there trough the regulator and up to the carb? Or should I do 6AN to the carb? And best place to buy AN fittings and hose? I was just going to use Summit but maybe here are cheaper alternatives? Thanks!

Go 8AN to the carb

Found a old pic of your boat.

Is that boat on a lift?

Think it was pushed out for a picture.

I checked the pick ups in my boat (37 Ol 95) and I have 4 bungs in the tank. U will have the same most likely. U will not need to change pick ups as they are 1/2 npt on the elbow out of the pick up. There is no way u need bigger than 1/2 npt with the power u are running. I run 150 + more hp per motor . Never a fuel pressure problem and I run 140 gph Holley mechanical 1/2 npt in and out of pump. I'm running -8 from tank to pump and -8 to distribution block and -6 to the dual 850 demons . 557 tall decks with 1071's.

This is great info!! So there are provisions for returns then by using the two other bungs? Does your setup utilize returns? Thanks for the info!

Justin

Yes u will have two extra bungs for returns. I set my system up and I do not run returns .
