How much power do you plan on making? I went with an OBX pump which according to Dsport's fuel pump tests was good for 680whp at 30 psi manifold pressure or 800bhp hp at 14 volts. At 15.5 volts it was good for 800whp or 950bhp. It's a $200 fuel pump as well, so I gave it a try. I searched and found nothing negative about OBX fuel pumps. I had an aeromotive A1000, might be a good pump but LOUD!
I'm currently running twin Walbro 255s but everything I've read says running 2 pumps is a bad idea. Better to run one properly sized pump. Just going to use one of my 255s to feed the surge tank. Should draw minimal amps with next to no discharge pressure.

A pic of my pump and surge tank. I won't actually have the pump connected directly to the surge, just has it on there for show. It's a really nice quality surge.
