My question centers around the fuel system, I want to run a fuel injection system but now have a carb on the engine. I would like to set the car up for the fuel injection, can a fuel injection, fuel system be regulated down to run a carb? I figured I would need a supply and return line but could use a recommendation on a fuel pump, I do want to run long distance with the car so I want to purchase a bullet proof pump. I have read your posts regarding the hot rod pour tour dilemas and the use of the bosch pump by some of you but Im not sure if this pump is a good choice for my application. Im also hoping the pump is quiet of coarse Im aware of the importance of mounting the pump using vibration Isolation material. Really would appreciate some recommendations on a fuel pump to use on this car, if it can only be one or the other regarding the carb vs fuel injection let me here what you would use?
Thanks Rich

Well, Aeromotive makes a nice return-style regulator that will let you run an EFI pump and still get it regulated down for a carb. You will have to replace it with their standard EFI regulator when you go to EFI, but it's built and looks the same so it's an easy swap. Most regulators cannot regulate a 50 psi EFI pump down to 7 psi or so and hold it there.
As far as a pump I'm going to use an Aeromotive A1000 pump again. I know, there were issues with them, but in all cases they were running them full speed all the time. I know the Mule had one that gave him problems on the Tour and then they installed their voltage reducer/controller that slows the pump down under idle/cruise areas and then goes to full voltage at a certain adjustable rpm. See it here:

Once he installed the voltage controller that was the end of the problems, although they did later swap out to Bosch OEM pumps; Mark needed something to design I guess!
The Aeromotive is quiet, preferably using rubber mounts as I do.
