I've got the Fore dual pump hat with twin 255LPH GT supercar pumps. Silent and works great.
I've been thinking of something extra and checked fuel pressure at the rail. I have a sensor on the driver side at the threaded port in the rail connected back to my Aeroforce analog input 2. At idle I'm seeing 62-63psi. At WOT I'm seeing 52-53psi. Stock fuel lines all around, no return, no nothing.
I think that's enough overhead for another 100 or so HP without any fuel system changes.
