Working out the plumbing details for my six conversion for the fuel lines. I've read a few threads and I'm still confused.
I'd like to keep the fuel pump in the front underneath the tank. (The 1975 car I'm staring with had it there to begin with.) What sort of pump should I use to get the 3.5 to 4.5 lbs pressure I need for the Weber 46s? Hardi, Bosch, Rotary, Holley? Do I need a return flow line? If I have a pump that flows at 3.5 lbs, do I need a pressure regulator. I also plan on installing a filter before the pump and one before each carb. Thanks, Karl |

Yeap, he’s right. When we went to carbs on the 3.0 we tried to use that rotary pump. It can’t keep up with 40’s let alone 46’s. :toilet: I have a fuel pressure gauge in the cockpit and you could watch it drop when you run on the track. I went back to the Holley with an adjustable fuel pressure regulator you can get the combination from Summit Racing for about $115. Part HLY –412-802-1 it pushs110 gph. Get a fuel pressure gauge. At idle the pressure is at 7-9. (IMG:style_emoticons/default/aktion035.gif)
