Lynn;  Tonight I was looking at the fuel pumps and if I run the Weber and the fuel injection system, do you see any reason to install 2 fuel pumps for each fuel system.  I thought that I would fly with the Weber first, then change so l could use either, but now it looks like I have all winter to get both systems running.  Two fuel pumps for each system seems like overkill and a lot of excess weight and plumbing.  What are your ideas on this, as you have mentioned, going the same route.  JohnD
I had not thought of that. But how about running just the high pressure pumps with a pressure regulator just in front of the carb. The fuel rail regulator for the injection would have no affect on the carb regulator.
 
You just need 3.5 Psi for the Weber. Although I use 6 Psi in the race car. And some carb tricks on top of that.
